Review: Flush even with floor - Great item. It’s flush like it states and looks great on our floor
Review: Installation Tips - This is not a difficult installation if you have the right tools. You will need a 3 1/2" hole saw, a router with a 1/4" rabbeting bit, a 6x32 tap and a valve lapping tool. First off you should practice this on a scrap piece of 2 by 10 before taking on your finished hardwood floor! Let me say that again; unless you do this all the time you need to practice this on a scrap piece of wood. As with any power tool you need to wear your eye and ear protection. When you use the hole saw be cautious as the large cutting surface will grab and violently twist the drill out of your hand. If your drill has a side handle be sure to use it. Take it slow and easy and let the saw do the work. Drilling a pilot hole first will also help keep the saw from skipping when you first start. Prep the box by using the 6-32 tap to cut threads into the box for the cover plate screws. For some reason my box did not have threads and you don't want to damage the nice brass cover screws trying to force them into non-threaded holes. Finally you will want to install the top cover and gasket to get the final finished height. This will be important in the next step. After cutting the 3 1/2 hole use your router and rabbeting bit to cut a 1/4 rabbet that will be deep enough so the finished box (this includes the gasket and top cover plate) will be flush with the floor. In my case this was about 7/16" but you will want to do this operation in small steps. As you get closer to the final depth it will be more difficult to lift the box out of the hole. That is where the valve lapping tool helps as it will easily lift the box out of the hole. Take your time getting down to the final depth by taking small cuts. OK now that you've practiced on a scrap piece of wood it is time to tackle the living room floor. First you must be absolutely sure you are installing the box in a compatible location. By this I mean you are not trying to drill through a floor joist or on top of electrical, plumbing, HVAC or other equipment that might be directly underneath your desired location. Drill a 1/8" hole all the way through the floor and go underneath the floor to verify the drill bit is indeed in a good location. If the drill came out too close to any obstacle you will at least have a good reference point for the final location. Plus a 1/8" hole is a lot easier to fix if you have to relocate the box. Before you start cutting the hole do yourself a favor and make a plastic tent around the work area. A couple of chairs and some black spring binding paper clips will keep the plastic in place. You are going to make a lot of saw dust and this will keep the mess confined to a small area. Now lets get our PPE on and get started. First enlarge the pilot hole slightly (it should be smaller than the drill bit in the hole saw arbor). To get the hole saw started you want to make sure the drill is perpendicular to the floor. If you are kneeling you can put the drills grip between your legs to help keep it from twisting out of your hands. Once you've cut through the finish floor you may need to stop and remove the wood from the inside of the hole saw before cutting the sub floor. Remember to go slow and let the saw to the work. Now that the hole is completed you will need to start on the rabbet cut. You will want to make several small cuts to get to the final depth instead of trying to make a few large cuts. Definitely wear eye and ear protection for this. As you get closer to the final depth the valve lapping tool will make it easier to insert and remove the box. Take your time and gradually sneak up on the final depth. Now that you've got the hole finished go ahead and secure the the box to the floor and complete the electrical phase of the install. I wholeheartedly recommend this box and hope these tips help.

## Questions & Answers

**Q: If Arlington makes 6” flush mount plates, could someone please post a link to those?**
A: I don't believe Arlington makes a true flush mounted floor box that is 6" in diameter.   You might try their FLBR5420 series (for wood floors).  These require a 5" hole in the floor and the top trim plate is 6 5/8" in diameter.  It is a surface mount version.

**Q: Will this ever be offered in an oil rubbed brass finish?**
A: You can find other options here on Amazon. Try searching Lew Electric 812-DFB. The below link might also work.

**Q: Do they make one for a single socket ?**
A: I don't know.  But this two-socket one comes with nickel-plated caps that screw in to any unused socket.  They are then flush and look nice.

**Q: Where can I get replacements for the rheaded plugs in nickel?**
A: We don't sell replacement plugs for this item. You may have to check with the manufacturer directly to see if they have the plugs or not.

### ⭐⭐⭐⭐ Could do with better instructions.
*by J***T on December 22, 2025*

Does what it’s meant to do, but instructions could be better. It’d be nice to see what depth it’s meant to be set at as opposed to guessing and shimming.
