## Questions & Answers

**Q: How do you measure the door to get the correct lock size ?**
A: If you replace a cylinder, we can measure the size from the previous cylinder you use. If you need to install a new cylinder to a new door, you can measure the door thickness, then choose a cylinder which is slightly longer than the door thickness. For example, if the door is 50mm thick, I suggest you use 60 or 70mm cylinder.

**Q: I require a 100mm lock 60mm from ext/40mm from int. will this lock meet this requirement ?**
A: Yes. Our cylinder 40/60mm key/key can exactly meet your requirement
