Rated 5 out of 5 by from Solid kit Straightforward replacement of a Yale lock, quality oozes from this product, if you've got to fit one it may as well be a decent one, and this is.

Rated 5 out of 5 by from Works very well and with the money I used this to do a lock change and it was relatively easy to change over.

Rated 5 out of 5 by from Very Strong & Secure I bought this lock to replace my old Yale when the internal return spring for the latch failed. The back plate dimensions were the same as the old so a straight forward replacement. A very good quality product. It is worth shopping around on the price as toolstation were the cheapest I found as I needed it the same day. Some of there direct competition are much more expensive even though they are all owned by the same parent company.

Rated 5 out of 5 by from Good Service I purchased a Yale nightlatch on line only to discover that it was the shortened version that would replace my old lock. After phoning I took it back to my nearest branch who swapped it for me after checking it against my template.

Rated 2 out of 5 by from Looks nice I did not like the barrel securing plate,thought it was cheap. Once all fitted the dead lock would sometimes jam.
