      what are the mounting screw dimension options? I assume the main one is 3.5 standard but I need a little smaller - like 3.25 but it would be nice to list the dimensions to be sure it works.

      Will this work for a 4x4 box?
      ByJul 7, 2023

      Answer This Question

      This cover is designed for 3-1/2 in. and 4 in. round and octagonal boxes. A 4x4 box is typically square, so this round cover won't be a suitable fit.

      Can this ceiling cover be used to cover a hole on the exterior/outside of the house?

      No, not a junction box. It rains outside and this would allow water to enter.

      By|Apr 1, 2026

        It's not waterproof - I used it to cover a very large hole over an interior ceiling fan outlet box - I wouldn't use if outside the house.

          What is the weight bearing capacity for this cover? I have one of these covers installed in my ceiling, and am looking to install a hook into the cover so that I may hang a disco ball from it.

          Answer This Question

          It's plastic and would not be a good idea to hang anything from it. If you did the disco ball may end up on some unknowing disco person's head. in additions the plastic cover snaps on the plastic braket. Heed the answer.

              It's only meant to hold itself up!

                Hi the distance between the screws is 2 inches. Would this plate work. If not do you have any recommendations?

                no ; wont work for 2 in . fits standard size octagon boxes .

                By|May 25, 2022

                  Yes ! This cover offers a universal fit. It is a screwless cover that has a center post that twists or presses into a nylon mounting bracket, that itself, has multiple screw hole placements.

                    This is a very good idea to cover a hole, simple and easy to install! Very nice looking on the wall.

                    Purchase these to replace some metal coverings our electrician installed. The metal ones never looked good and were shiny. These look much better and will be painting them to blend better with the ceiling. I highly recommended and am excited to see the end result after painting.

                    It is plastic, not recommended for high traffic. Nice cover. I removed a round, high position wall light in a hallway.

                    Worked for what I needed, though wish it was a little more sturdy. You install the plastic bracket over the j-box and then just push the post of the cover into the hole in the bracket. I'm sure it will hold, but I feel like a screw post or other type of attachment might be stronger.

                    Great ceiling box cover
                    Easy to install. Looks great. I had to use my own screws, but not an issue as I have lots spares. The trick to installing is to gently insert into the center hole and then rotate it to screw it in as the little pole has threading on it. That also makes it easy to remove and adjust as necessary.

                      these suck. will not sit flush with the ceiling.
                      ive attepted to push the cover onto the plastic support failed, ive attempted to "screw the plate onto the plastic support also failed. i just wished Carlon still made their version as they fit perfect.

                        It looks great. It is paintable. Covered up our prewired hole for a chandelier in our dining room. Good white color to match the ceiling.
