In 2012 we purchased a house built about 1985. Unfortunately the previous owners had not maintained the place very well. The original front door is of a good quality solid wood so we did not wish to change it. The original lock however was worn and the keys kept jamming. We were able to find the exact same lock brand new on your site thus avoiding having to cut into the door to fit a different sized/new design new lock.

The lock we got from you was an exact replacement of the old one and took five minute to fit. Perfect ! Let's hope your new lock lasts as long as the original - 29 years.

Not only did we find exactly what we were looking for on your site but the service was excellent - next day delivery. Thankyou.

A good product, which it was very difficult to find elsewhere. The 5 lever lock is a good security mechanism which I use on my back door. We also have one on the kitchen door which will require changing in the not distant future and I shall use this company again.

Very good quality, I bought it as a replacement, almost identical to the original one, so it was a case of take out the old, and slip in the new, easee peasee as they say, plus it was very handy being able to buy an extra key.

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.
