Membrane box M3 35, Concrete construction concrete box

With the M3 35 membrane box for cast-in-place concrete and prefabrication, cables and conduits can be inserted tool-free into the M15 - M32 combination entries. Thanks to membrane technology, the boxes are absolutely concrete-tight. With SCS connection technology, multiple boxes can be connected quickly and securely in accordance with standards. Cutting out the webs allows for easy through-wiring as well as simple installation of pre-wired devices. The integrated conduit grip ensures reliable strain relief. Subsequent cutting of the conduits is not necessary. The clip-on wings allow the box to be easily and quickly attached to the steel reinforcement without the need for a counter-bearing or support element. Due to the special design of the wings, the standard 15 cm distance to the door formwork is also maintained. Rotating the wings allows for use with concrete covers between 20 and 60 mm. Thanks to its compact octagonal design with a depth of 48 mm, the M3 35 membrane box can also be used in confined spaces without compromising structural integrity. The membrane sealing lip ensures a clean finish and prevents concrete slurry from entering, making the Primo M3 35 membrane box with a 35 mm installation opening also perfect for exposed concrete. With a 35 mm installation opening, the box is ideal as a luminaire outlet.
