Answer This Question

A:  There is no reason why you can't. In fact I have one in a spot where I'm planning to run some NM to but haven't yet, so am running an extension cord

by|Dec 15, 2022

    A:  You can pass an extension cord through this but this is not meant to be or should be used as a junction box for anything other than low-voltage cables.

        Answer This Question

        A:  No that would be a violation of code as you would have wire connections (risk of fire) not contained by drywall, metal or an approved plastic.

        by|Dec 1, 2022

          A:  No. This is for low voltage ethernet cable, phone cable, coaxial cable...

          by|Nov 8, 2023

            A:  I would not use it for that purpose. It leave hot wires exposed in the wall. This is primarily for non-electrical uses like for multimedia (i.e. coax, ethernet, hdmi, speakers connectors, etc.)

              Q:Is there some trick to screwing a wall plate to this bracket? I tried to pair this with https://www.homedepot.com/p/Commercial-Electric-White-1-Gang-1-Decorator-Rocker-1-Duplex-Wall-Plate-1-Pack-5001-WH/206428112, but the screws won't hold.

              A:  No trick, here. Mine went together easily. The screws just tapped into the plastic holes in the orange bracket.

              by|Feb 24, 2022

                A:  I don't think that box is designed for mounting a faceplate directly to it. You probably need something like this as well: https://www.homedepot.com/p/Commercial-Electric-1-Gang-Low-Voltage-Mounting-Bracket-5041/206415713

                by|Feb 24, 2022

                  A:  That combo should work fine. I’ve done it many times. Make sure you’re lined up with both of the smaller holes toward the middle of the bracket. Also metal vs plastic, metal wins so if you used a screw gun and tried to tighten too much, the holes could have been stripped out. 

                  by|Feb 27, 2022

                    A:  I had the same issue. A standard 6-32 screw will work as long as it's long enough. The first screws I tried wouldn't thread in, but I switched to 1/2" long screws and they worked fine.

                      Makes Low Voltage Work More Enjoyable
                      Previous home owner had a traditional single gang box installed with coaxial cable for internet running through it. When the time came to upgrade to fiber I decided to try a low voltage box after reading about its use on misc forums. Simple solution and effective -Opens up wall for greater visibility when working -Prevents tight turns and kinks in fragile fiber wire that you may get when working with typical electrical boxes. Wings hold the frame plenty secure to existing drywall.

                        Easy to install and secure on lath and plaster
                        I used this to add an ethernet outlet in a lath and plaster wall. The clamping wings had just enough room for the lath and plaster (though one could use different screws for even thicker walls). It feels secure for the ethernet jacks.

                          Nice and simple for places without an existing outlet
                          This is a nice simple product for a DYI project. I installed a wired home network and this came in handle for places that didn't previously have a outlet. Very simple to use.

                            These wall plate sleeves have large open backs to accommodate multiple low-V cabling. Mounts to a variety of wallboard thickness with their incorporated adjustable clamps. My single gang box "keystone" project housed 3 HDMI, 1 CAT5e, 1 USB and a "F-connector". Tip: Patiently fish with added "pull-strings" taped up smooth in one group with masking-tape to avoid snags.

                            These are very poorly made and locking tabs break way too easily. Bought two of these but both broke either during assembly or shortly thereafter. The 1-Gang 20 cu. in.

                              We are doing a laminate floor in family room and had to do a channel in subfloor for a phone line, ethernet and some surround speakers into the wall that can't be rerouted from basement. I like these boxes over having to install full boxes which are only required for electrical. However on at least one of the ears of each box the screws are really hard to turn into the plastic and I have a good phillips screwdriver. Had to really push into them to keep from stripping the screw. I wish they were star drive that is all I use for my construction projects. You may wonder why ethernet, I also use it for the best speed on apple tv as our wireless network is weighed down with 10-12 devices and i like having options.
