The existing lock broken and Gainsborough were no help apart from selling me a complete new lock. This part fixed the old lock and working as good as new.

Great service again use the lock shop a bit and always really good with product,service and delivery

The lock arrived undamaged in good in good time. I am not a locksmith but a DIYer and found that the installation was straightforward although you had to take particular care about where internal components are when taking apart to install the barrel. The old lock was a help here. An economic solution.
