Union BS 5-Lever Mortice Deadlock Stainless Steel 2½" / 64mm is rated 1.5 out of 5 by 2.
Rated 2 out of 5 by from Couple of issues The first, on unboxing the lock, is the requirement for an 18mm drill bit - hardly a common size. Had to go back to Screwfix next day to buy one. The second still needs attention. Before fitting, I noticed that the cover plate was a tight fit over the deadbolt. Once installed, when the fixing screws were tightened, the lock would not operate as the bolt was catching edge of the faceplate. All things considered, this lock was more difficult than average to install. I haven't fitted a Union 5-lever lock for a while (have fitted several Era deadlocks with no issues) and I'll now probably avoid Union in future.

Rated 1 out of 5 by from Rubbish Lock We purchased two of these locks as we had a break in and had to renew a door. Two brand new locks and in less than a week one has malfunctioned in the locked position which has caused us huge problems. Only bought them as out of stock of more trusted brands - steer clear
