Further solutions for concrete installation
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 reliably strain-relieved and absolutely concrete-tight.
Do the Wings hold on to 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.
