Unlike comparable products, the Primo Universal plaster cover is convex to minimise the thickness of the applied plaster on the box. Combined with the Signal pin in the signal colour red, the Flush mounting box is quickly found.
For clean contours without plaster breakouts, the stable signal cover is pressed in and automatically pops outwards again. Now the cover can be conveniently removed by hand or with the help of the centring hole with a 68 mm holesaw. Due to the standardised size of the flush mounting cover, it is easily attached to all common boxes. The red plaster cover can also be used without any problems when the building site cools down below freezing.
