“Outstanding fast delivery on two pieces of an ancient Wolverine bath stem for Kohler - from the early 40s I think. The new one has a different body design, but it screwed directly into the old hot/cold tree and was the exact 6" length. Forty eight hours after installation now, and all remains fine. Also, kudos to the people who set up the website and ordering process. Great work - clear photos and info ! PS: I'm not an employee or family...lol. I retired from electrical wholesaling here outside Chicago and I appreciate a good job. ”

“Hey these guys are awesome! If you need a part for a fixture they have it send a picture and they can tell you what it is, they know their stuff, they have the weird obscure things you can't find unless you get a whole trim kit or whatever. Worth the trip and the money. They save you tons of time definitely visit ”
