Question: I currently have a plate with one single screw in the center.  I am replacing the tub, so would I need some type of adapter to use the 2 screw plate?
Document: I just finished installing this drain and overflow cover and I am very pleased with the look and quality of these items. The drain assembly is made to fit a 1-3/8" pipe or a 1-1/2" pipe with an included threaded adapter. My tub needed the 1-1/2" adapter. I was scared that if I ever needed to remove the drain, the adapter assembly would not come out with the drain.
Not being a fan of the "toe release" drains, I was looking for something mechanically simple. This item filled the need and it the finish is exactly what was expected. I would purchase this again.
It all screwed right into the tub drain pipe and it works great. I would by this again in a minute. I was not able to find a brushed nickel assembly like this at Home Depot, Lowes, or Ace Hardware. The drain assembly is a nice, heavy, well built piece.
Great quality. Threaded easily in a fitting that is probably 45 years old. The drain rocks! Get one.....even if you don't need it....
All this was really easy to install and solid. I didn't need the collar, but everything was available and good quality.
I was changing out my tub hardware and found just the right parts in brushed nickel. These were delivered quickly and in great shape. Thanks Bob!
We were looking for a tub drain that would seal and not have to many moving parts so we did not want to get a trip lever drain. Bought a trip lever drain and removed the trip lever and insides to it and used this instead. Works great with a 3 year old that loves bath time. Plus my wife has hair that always clogs the drain. This does not have the obstructions to let hair get stuck. Finish is awesome.
Quality was more than I expected and I was extremely pleased. I liked the different size applications. Would highly recommend.
This is a very easy review to write. For the amount of money I paid, it is well worth it. The finish matches all the other accessories in my bath, perfectly. I have a hodge podge of various manufacturers products installed. I just didn't find a single style that I liked. The quality is right in line with Moen, for half the price!
Haa a problem finding 1 1/4&#34; threads in the big box stores. This kit fit both 1/1/4&#34; and 1 1/2&#34;. Easy to assemble and looks good. Arrived quickly
Answer: No you shouldn't. When you remove your existing overflow plate you should see a piece that runs between 2 screws and has a hole in the center for the single screw you have. Remove the 2 screws and the plate. Use the two screw holes for the new cover.
