Rated 4 out of 5 by from Very happy with the purchase! :) Installed it myself without any problem. Took the old one off easily and the new one fitted perfectly. Had to cut the extra metal bit to adjust with the door depth but apart from that, it was an easy installation for a novice like myself. Very pleased!

Rated 1 out of 5 by from Web site listing error Item 19120 listed as having a 40mm backset on the web site listing but on arrival it was a 60mm backset. Had to return this. Your web site listing shows incorrect product info so very frustrating.

Rated 5 out of 5 by from Substantial lock These are great locks. I have fitted a few in the past and never had a problem with them. They come with 3 keys so that can save a trip to get spares cut. Much heavier duty than a standard night latch, but a but more work to fit. Follow the instructions and it is fine.

Rated 1 out of 5 by from Poor quality Fitted this for a customer and it fails within a week, not the first problem with ERA products unfortunately

Rated 5 out of 5 by from looks good, works well I needed to replace s lock that was getting increasingly difficult to unlock and going into a half glazed door so needed to have a key lock on the inside. It was not a direct replacement but not to taxing to fit with a bit of DIY experience and a few tools. It locks with a good reassuring click.

Rated 4 out of 5 by from really solid construction and action good lock but a few pitfalls. The screws may will sheer if installing in hardwood or aluminium, big headache. the latch plate would be more secure if had fixing points on 2 axis.
