Arlington Industries LVS3 Screw On Low Voltage Mounting Bracket features shallow mounting depth which allows for more wires to be run in the wall cavities. The shallow mounting depth also works better with reversible wall plates since the box itself is not obstructing the wire passage. Arlington Industries has also designed their new construction brackets to have a front nail flange as well as a full outer flange for sheetrock to be backed up to ensuring proper support for the sheetrock and proper depth. The LVN3 and the LVS3 brackets also feature front flange nail holes on both sides of the boxes so the box can be supported on the both side by studs. Installation: The LVS3 features integrated onboard screws that are ready to be driven directly into wall studs in preparation for future outlets. The bracket is designed to be installed in the wall and attached to a stud so you can eventually mount plates flush against the wall. The LVS3 brackets are simple to install and allow for a durable but professional wall outlet installation. IMPORTANT: For Low Voltage Class 2 Use Only.
