An Innovative Approach to Low Voltage Wiring

Low Price Guarantee


What's special about these communications boxes?


When installing structural network wiring, it is best to employ products that will not need to be replaced anytime in the near future. 5 SQUARE® back boxes by RANDL® are practically future-proof, containing nearly double the internal space of standard 4 square back boxes. Maintaining the proper bend radius and generally keeping cables organized is also a breeze, thanks to its integrated cable management prongs.
