## Questions & Answers

**Q: When the lock says 40mm or 60mm etc how do you know which one is needed. Do you measure thickness of door?**
A: 40mm or 60mm is the backset of the lock.Basically the space from the edge of the door (or lock) to the centre of the spindle.It's essential if you are replacing an old lock and don't want to move the position of the handle.

**Q: HI,  what tools will i need to fit this myself please?  Thank you!**
A: Instruction are included but you will need a mains powered drill and a drill bit big enough to bore at least a 1inch hole in the door if there is no hole already,  a cross bit screwdriver and a small drill to start the screw holes. Also a chisel and mallet to inset the lock and latch to the door and door post. Good luck!

**Q: Does the locking mechanism have a 90 degree angle lip that wraps around the door like the 60mm version. my old era lock sat flush against the door**
A: Hi Todd, yes lock sits on the inside face of the door and the lip extends approx. 28mm across the end of the door and is secured through the two holes you can se in the top right picture (if you zoom in). If you viewed from above the lock it would appear as an L-shape. You need to rebate the door end to allow the 28mm lip to sit flush with the door end.  Hope that helps!

**Q: Is it possible to install the lock on the door, 40 mm thick.**
A: Yes

## Customer Reviews

### ⭐⭐⭐⭐⭐ Secure, well built and stylish.
*by R***D on 8 April 2017*

Very decent product.Easy to fit and clear diagrams / instructions and includes a drilling / hole template.Very secure and well built.Can attest to the security as my better half managed to lock herself out (door slammed behind her with the keys inside the house)It took a locksmith (with a decent SDS drill) several drill bits and 20 minutes to drill through the lock (apparently they are anti drill).He wanted to give up and try to get in through the rear instead. Told him no chance as he'd already started drilling this lock. (I'm sure he would love to charge extra to fix both locks). Anyway, he eventually got in..No idea how resistant they are to picking, difficult to find a locksmith these days who can actually do anything more than drill and charge you extortionate amounts to refit.

### ⭐⭐⭐⭐ Solid / and home insurance approved
*by B***N on 9 September 2014*

Fantastic solid insurance approved latch. The keys do not seem to work very smoothly (even before fitting) but this didn't matter since I was using the Yale electronic touch pad in conjunction with the night latch.The auto deadlock is simple but very effective- genius.

### ⭐⭐⭐⭐⭐ Strong and robust lock.
*by S***Y on 7 January 2018*

This feels a very good secure lock. it's tricky to fit, especially in place of an existing standard security lock.but this would probably be the case for all locks of this security level. If you are not experienced in fitting this type of lock, make sure you have all your tools to hand, and plan on it taking several hours - or get someone else to do it. It's good value if you need a lock of this calibre and security rating. I would buy again.
