## Description

Round box Adapter only. Round box Adapter> adapts single gang cover to round receptacle box for use with Hubbell - TAYMAC weatherproof covers. The name trusted by professionals.

Review: Great solution - I removed a single LED round ceiling light in my garage so I could install some more effective strip LED lights. I needed to be able to simply plug those new strip lights in, so I wanted to convert the old round ceiling box into a receptacle. This adapter worked out perfectly. (See photo) I made sure to measure the box and compare it to the dimensions listed in the ad before ordering, as I noticed a few reviewers said this adapter did not work for their application. For me, no problem. The installation went fairly easily, however, I did have to 'egg out' one of the holes in the adapter just a bit because the screw was just a tad out of alignment with the mounting hole on the box. I just took a same size drill bit as the hole in the adapter and wallowed out the plastic, just a tiny bit. This was all it took to allow me to line up the screws to the holes. Then I added a cover plate and the install was done. I am very happy with the end results. Now, I have excellent and more thorough lighting in my garage, thanks to this adapter and new LED strip lights.
Review: Works like a champ - Worked perfectly and the foam on the back seals the rectangular box very well.

### ⭐⭐⭐⭐ Good quality, but overpriced
*by W***J on September 24, 2023*

If you need a round box adapter (I did!) this is a very good one, but it’s severely overpriced. It’s a piece of molded plastic with a closed-cell foam “gasket” attached to the back. It works very well. However, I was convinced there had to be a similar one at a better price — there is! Home Depot carries Titan3 Technology TWAR1PG 1-gang round adapter for $3.98. That’s almost $10 cheaper than this item. I agree that it’s a good quality round box adapter, but I disagree with the reviewers that have said it’s good value for the money. I needed 3 more and saved nearly $30!
