Good well made lock. I bought it to replace an old worn-out lock. The website information allowed me to select the right lock. The dimensions were exact and fitted into the space where the previous lock was. Good price by comparison with other suppliers.

As always top quality, I have fitted these locks for years and found them to be the best!

One of the only good quality sash locks one can buy these days. An oak front door, costing £1000+, deserved the best.

The fitting was carried out by my joiner so I am unable to comment, although the instructions seemed comprehensive. A very sharp set of chisels clearly required.

Will be able to give you full report in 25 years time!

I will in a month or so be in need of further door furniture and will have no hesitation in contacting Safe at that stage as your range of quality items is so extensive.

It is most useful to be able to purchase on the web with the confidence your company gives.

Thank you

Living out in 'the sticks' so to speak, security is very important to me and my family. When we moved in to our new home , i was very suprised at the poor quality of the existing locks, shallow tonge, poor rebate in the door, and only 3 lever ! It felt as though a good nudge with a strong shoulder would see it cave in. On selecting a replacement, i decided to find a world leader in it's field and naturaly was drawn to Union, as i had used them before and found the products to be robust and very well made and with three keys per lock. Delivery from order was very prompt and the fitting by my carpenter was strait forward. The added bonus is a reduction in my house insurance as this lock is on their approved list.

I am replacing a Chubb 7 lever front door lock, same size as this lock. The bolt projection from the current lock is 14mm, but the recess in the door jamb part of the lock is 22mm. So would this 3K74E be OK as a replacement?
George Naylor, Stevenage
This lock has a 20mm bolt projection so you should be absolutely fine with your existing 22mm recess.
