SOLUTIONS FOR CAST-IN-PLACE CONCRETE
Concrete Boxes, Installation Housings & more
Construction without cast-in-place concrete is no longer conceivable – and rightly so! After all, it allows floor slabs and ceilings slabs to be manufactured with little effort. But that’s not all. As a design element, concrete has long been very popular with those who want to achieve an urbane look. However, visible concrete places high demands on electrical installations in particular – errors not only cost time, but are usually also associated with high expenses. This is exactly where Primo has come in and developed a comprehensive system of clever installation aids for use in cast-in-place concrete.
All our products demonstrate our many years of experience in the industry and the close contact to the electricians. With the new Primo concrete series, you save high costs and time-consuming work in daily installation. Discover our extraordinary product quality! Discover our excellent product quality:

The electrician thus saves work, time and money and is well able to meet the growing demands on the quality of installation work.
Transitions
Claw Sleeves, Wall & Ceiling Transitions
The C-Series combines the latest technoglogy from grommets, sleeves and claw sleeves. Thanks to the in-house conduit grip technoglogy, the transitions and connectors guarantee absolutely reliable strain relief in concrete construction – regardless of which conduit manufacturer is used. Additional fixation with adhesive tape or other expedients, as it was previously the case, is no longer necessary. The special highlight of the new series are the optional wings, with which the C-Series can be attached directly to the steel reinforcement.
Concrete Boxes
Universal Junction Box
The Universal Junction Box can be used as a ceiling junction box and offers the electrican huge installation space. Thanks to the in-house membrane technology, a high-quality installation can be achieved in the shortest possible time. See for yourself. The 3-part structure with lid, box and front part allows, among other things, the placement of the front part before the reinforcement is being installed. Thanks to the low overall height, the steel can then be easily moved and positioned. You can’t get more flexibility and efficiency!
Power current
CEE-Box
The membrane box M1 CEE, an advancement of the widely used M-Series, offers the electrician numerous advantages when installing three-phase current. The highlight is the three-part CBS system: The cover is quickly installed thanks to the nail guide. Due to the box’s clever membrane technology, cables and conduits can simply be inserted – absolutely concrete-tight and reliably strain-relieved – in no time at all. The specially designed sealing ring guarantees a protection class of IP 44, which is necessary for CEE plugs according to DIN 60309.
Housings
The clever alternative standardised installation parts
Tinkering belongs to yesterday! In order to facilitate the creation of recesses in cast-in-place concrete, Primo has developed practical and Standardised Special Installation Housings. This eliminates the time-consuming creation of individual wooden or foam polystyrene recesses for the electrician. In addition, the Primo products can simply be recycled after concreting and are therefore more sustainable than the classic methods. The Primo Ventilation Sleeve is ideal for ventilation recesses, while the Primo Schalfix is recommended for all other areas of application.
Uni-Flexx
Retrofitting in ceiling slabs
Correct planning is crucial in concrete construction, because concrete is unforgiving of mistakes – until now. With the Uni-Flexx you can add spots, loudspeakers or other built-in devices in ceiling slabs that have already been cast. The required core drill hole is much smaller and therefore significantly cheaper than usual. This increases your flexibility on the construction site and saves you a lot of time and money. See for yourself.
Primo advantages in everyday work
“The XL-Series with its side entries is a very innovative system. The insertion without additional tools offers immense time savings and it ensures direct reliable strain relief for conduits. It is also very practical that the cover can be opened beforehand. In this way, the installation can be well prepared.”
Walter Kunz, Managing Director iTECH Elektro GMBH
Why does the M1 cost more than a standard concrete box?
Yes, the M1 is a bit more expensive than competing products. However, what’s the most expensive part of the job? Labor! Thanks to modern membrane technology, the boxes are absolutely concrete-tight, and cables and conduits can be inserted without tools. The integrated conduit grip ensures reliable strain relief – eliminating tedious rework and subsequent conduit cutting, which significantly saves labor.
With the M1, you have the huge advantage of only needing one box for the entire concrete installation. The M1 can be used as a device connection box, wing concrete box, ceiling connection box, large-diameter conduit box, or electronics box. This not only reduces your storage costs, but also eliminates the risk of the installer selecting the wrong product.
Does the conduit stay in the box?
Yes, thanks to the conduit grip of the membrane boxes, everything is reliable strain-relieved and absolutely concrete-tight.
Do the Wings hold on the M-Series?
Yes, the Wings hold on to all Primo concrete products: Membrane Boxes, Installation Housings, Universal Junction Boxes, Grommets, Sleeves and Wall and Ceiling Transitions.
Why is there no thread for ceiling hooks?
We did this deliberately because construction sites are always dirty. If there’s dirt in the thread when you screw in the ceiling hook, you might strip the thread.
Can membrane technology withstand the pressure of concrete?
Yes, it’s been tested. We also have many satisfied customers who use our concrete boxes.
Can the M1 be used as a CEE socket?
For this purpose, we offer the special M1 CEE in our range. This is a further development of our M1, which has already been installed millions of times, and is designed to meet the specific requirements of high-voltage installations.
Which CEE sockets fit into the M1 CEE?
Any conventional CEE socket manufacturer fits into the M1 CEE. It is therefore suitable for use with 16 A CEE device inserts.
What protection class is achieved with the M1 CEE?
The M1 CEE sealing ring with protection class IP 44 prevents moisture from ingressing the socket, thereby fulfilling the required DIN 60309 for CEE plugs.
Why do the XL-Series Installation Housings cost more than standard luminaire installation housings?
The XL-Series is priced slightly higher than competing products. However, what’s the most expensive part of the job? Labor! Thanks to modern membrane technology, the Installation Housings are absolutely concrete-tight, and cables and conduits can be inserted without tools. The integrated conduit grip ensures reliable strain relief – eliminating tedious rework and subsequent conduit cutting, which significantly saves labor.
The XL-Series Installation Housings are perfect for mounting all types of components, such as lights, loudspeakers or other built-in devices.
Why is the cover removable?
The removable cover allows cables and conduits to be pulled into the Installation Housing before concreting. Thanks to the integrated membrane sealing lip, everything remains absolutely concrete-tight.
Is it possible to expand the Installation Housings with a tunnel?
Yes, an optional Universal Tunnel is available for the XL 150, XL 200, and XL 250 installation housings. The Universal Tunnel creates additional installation space, ideal for larger electronic components, for example. It can be universally attached to all installation housings in the XL-Series.
Are built-in devices in the Installation Housings protected against overheating?
The smart design of the Installation Housings enable optimal thermal management – even when using the Universal Tunnel.
Why does the Universal Junction Box cost more than a standard concrete container?
The Universal Junction Box is extremely versatile. Thanks to its modern membrane technology, the box is absolutely concrete-tight, and cables and conduits can be inserted without tools. The integrated conduit grip ensures reliable strain relief – completely eliminating tedious rework and subsequent conduit cutting, significantly saving time.
The three-part design with cover, box, and front part allows, among other things, the front part to be positioned before the reinforcement is installed, which clearly sets the Primo Universal Junction Box apart from common two-part competitor products. The M40 inlet is also unique on the market. Additional flexibility is offered by the various front parts in 60 mm and 70 mm, as well as an Optional Divider for two separate circuits in one box. Another advantage of the three-part Universal Junction Box is that you can nail the base plate on first, then, after the first layer of iron, place the box on it and screw on the cover – thus, the cover cannot get lost.
Is the Universal Junction Box available in different sizes?
The Universal Junction Box is available in two versions. You can choose between a front part with a 60 mm diameter and a front part with a 70 mm diameter.
Can two separate circuits be installed in one box?
Yes, the Optional Divider is suitable for this purpose. It is easily inserted into the Universal Junction Box, allowing for a clean and safe separation of the two circuits.
How many Newtons can the claw sleeves hold?
The claw sleeves hold up to 380 N.
Which conduits do the claw sleeves hold?
Thanks to the conduit grip technology, the transitions and connectors ensure absolutely reliable strain relief – regardless of which pipe manufacturer is used. Additional fixation with adhesive tape or other expedients, as it was previously the case, is no longer necessary.
What is the support on the sleeve for?
This is the support anchor. It supports the sleeve and gives it additional stability so it doesn’t break.
Can the C-Series grommets and sleeves / wall and ceiling transitions be combined with each other?
Yes, thanks to the thought-out plug-in system of the C-Series, all sizes can be combined safely and securely.
Can a conduit be continued into a drywall after concreting?
Yes, since our starting product is a claw sleeve, continuing is not a problem.
How can the Schalfix be disposed of after removal?
The Schalfix does not have to be disposed of as hazardous waste, but can be conveniently disposed of with household plastic waste.
How is the ventilation outlet mounted on the Ventilation Sleeve?
Simply screw the adapter ring onto the Ventilation Sleeve without pre-drilling and the ventilation outlet can be installed.
Which borehole is required for the Uni-Flexx?
A 74 mm drill hole is sufficient to create the installation opening for the Uni-Flexx. This can be done by any installer. The Primo High-Speed Driller with our Concrete Core Bit is ideal for this purpose.
Alternatively, you can drill the hole using a standard 75 mm or 82 mm diameter core bit. The resulting gap between the Uni-Flexx and the hole can either be covered by the device used (ceiling spotlight, speaker, etc.) or can be filled during the planned filling process.
What is the Quickstar Formwork Protector used for?
The Quickstar Formwork Protector is a clever tool in concrete construction, enabling safe and stable transitions in no time. It’s particularly suitable for tight spaces and, thanks to the stabilizing flap, retains its shape even after concreting.
How does the Nailer work?
Our nailing aid for concrete construction products makes nailing boxes easier. The 40 cm long Nailer nails covers and boxes to the formwork without injuring your fingers – even after the second reinforcement has already been installed. The pin spacing is 60 mm, allowing any standard box cover to be picked up, precisely positioned, and nailed into place.
