Exact replacement and excellent quality. Very satisfied.

The replacement Atrium lock parts replicate my original lock precisely except for the handle bushings. They have too small an inside diameter to fit the handles. I had to use the bushings that came off the original lock handles. I don’t know why Countryside has not corrected this issue since it had been reported in other reviews. Otherwise, the replacement works perfectly.

Perfect fit!

I was able to get a replacement lock for an older door with just one search. It was a perfect fit.


Great service

Great Service

The replacement Atrium door lock was delivered quickly and was the correct size. Unfortunately the spindle connecting the two door handles was too short (3” instead of 3.5”). And the bushings were too thick to fit over the handles. I sanded down the bushings, then called Countryside for a replacement spindle, which arrived one week later in the mail. I could not use the old shingle because I had to cut it off during disassembly. And the old bushings were completely worn out.
Except for the wrong size parts I would have given five stars.
