The LVS3 is a fantastic, easy to install solution when incorporating data, communications, fiber optics, or any other low voltage wiring into a building project. Being made of high-impact plastic, they have a lower cost than mud rings or their steel counterparts. Installation is quick and easy thanks to their captive screws and built-in cable tie off loop. Simply screw them into a metal stud for secure placement without pushback from installed drywall. UL and CSA listed. Made in the USA.
