Weslock 640J Reviews

Rated 4 out of 5 by from Attractive fixture and hubby was able to install.

Rated 5 out of 5 by from Great Quailty I am very pleased with the quality and look of this lockset. If you are not looking to spend a fortune and want a high end look, this is the one. I even had a contractor comment on how nice they are with a very sturdy and solid feel.

Rated 5 out of 5 by from Nice knob These knobs look great. We actually had a problem with this one - the keyed one. The ring around the neck was broken. They replaced it quickly, so no issue there. The new knob was easy to install and looks great.

Rated 5 out of 5 by from Perfect... The simplistically modern design of the knob, both in style and color, suited the contemporary decor throughout the house perfectly. Comfortable grip and easy to turn...great purchase.

Rated 5 out of 5 by from Great product The installation was easy- it comes with different mounting hardware options- nice touch. It took me just a couple of minutes to replace and old knob. It has a rich finish and operates very smoothly.

Rated 4 out of 5 by from Great knobs for the price We bought all baldwin for the interior of our home but I couldn't see spending another $700 for 5 exterior knobs and deadbolts, so I picked this one to match with all my interior knobs. These are nice quality, match well with the Baldwin oil rubbed bronze, and were easy to install. Had one issue with a deadbolt and a stripped screw - quick customer service that just sent me a new one keyed like the other 5 I had. No problems and no hassles. This knob is definitely worth the price, and great customer service here.
