Bought this to replace an original Chubb 5 lever sashlock that had lasted 32 years. The replaced Chubb lock had a worn keyhole opening in the case which meant that the key was able to move out of alignment and would not then always engage with the internal levers properly, and there was no easy way to repair the lock case. This new Union lock is a direct replacement for the original Chubb lock, having exactly the same external dimensions and needing only the keyhole opening in the door to be enlarged by a couple of millimetres rearwards as the new case's keyhole was set a couple of millimetres further back in the replacement's lock case. The lock looks externally to be to the same standard of construction as the original and hopefully the internals are of the same standard, in which case it should last another 30 years or so.

What is the difference between 3K74 & 3K75 apart from the price?
Barry Hartman, Helston
The Union 3K74 - 5 Lever Sashlock (67mm) is fitted with an anti drill plate to protect the lock mechanism from attack. This is the only difference. They are exactly the same size as the 3K75 locks.
