“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 ”

“Just want to say THANK YOU for your help with this! I couldn't believe the handle arrived Thursday (after ordering Wednesday). I brought it up to my dad's house Friday and just looking at it I didn't think it was going to fit....but it fit perfectly. So appreciative for your expertise and quick shipping! ”
