Replacing Chubb 7-lever mortice lock
I bought this lock to replace a 30 year old Chubb 7-lever mortice lock. I had read that this model was a good substitute and I can confirm that it is. The lock is marginally wider but a few shaves with a wide chisel was all that was needed and now we have a lock that works smoothly.

Great Retro Chubb Replacement
Slightly thicker than the retro Chubb mortice lock it was replacing but otherwise fits perfectly.

An exact replica
It was a perfect fit in place of the original Chubb lock.
