easy installation
We've had an almost identical one on our door since we moved in 40 years ago, sadly it broke, but this was 95% IDENTICAL to the original, so we swapped them over and reused our barral so no new keys were needed. Possibly not quite as sturdy as the original, but very happy with this replacement.
