## Questions & Answers

**Q: can you advise size in imperial 19.4cmx11.4cmx3.4cm**
A: 19.4 x 11.6 x 3.2 cm actually refers to the size of the box the lock is delivered in !I found the actual dimensions elsewhere: https://www.locksonline.co.uk/acatalog/British-Standard-BS3621-Era-Fortress-Sash-Lock.htmlThanks Amazon (sarcasm)

**Q: Can I fit this to a 44mm thick hardwood exterior door?**
A: Checked my door, lock needs about 17 mm recess into door, this would then leave 27 mm, ie 13 mm each side of lock, should be sufficient as door is hardwood !. When I was looking for lock for my workshop 17 mm seemed the most narrow available.  Hope this helps.

**Q: What is the measurement in between the two bolts - existing one is 7mm between both bolts**
A: Measuring from the underside of the latch to the top of the bolt on this particular lock is 12mm, hope that is helpful.

**Q: What measurement is 64mm? i need to replace a faulty lock and obviously want to buy the right size. existing lock is era but can't see anything 64mm**
A: It's the depth of the lock. i.e the mortice in the door needs to be 64mm or more in depth to house the lock.
