Rated 5 out of 5 by 4 reviewers.
Rated 5 out of 5 by almost a perfect fit. Just slightly longer than OEM equipment for my door, small amount of filing on corner of mounting and went together perfectly very happy doors are secure again. May 21, 2014
Rated 5 out of 5 by Perfect replacement Make sure you get the 45 degree lock and not the vertical if you are offset from the handle. Also follow the instructions closely as it is easy to rush in and get it wrong. Otherwise this is just the lock I needed and HD delivered as promised. I had to go online as all the store locks were vertical. April 2, 2013
Rated 5 out of 5 by This lock fixed suited my needs. I needed to replace the door handle and lock for my patio door. Door was installed long before I came into the home. This lock met the needs and installed in minutes. Now the new owners of my home think it has been there all the time. January 28, 2014
