How do i adjust the size of the entrance lock when it says 35mm to 55mm

[Davehelp]

Combination lock says it fits 35m to 55m door but doesn’t tell you how to adjust the size. My door is 35mm. System wouldn’t let me add photo.

Hi Eric, photo as requested. Dave

There should be enough thread in the exterior cylinder to let the screw tighten down to fit a 35mm door.

Latch is adjustable for 60 or 70mm backset. It should be having the cross on the center of the hole.

The instructions given are never that great unfortunatly.

Hi @Davehelp

I've spoken to the store's hardware specialist. You will notice that the cross pins that join the pieces together have stamped cutting lines on them. This is placed so that you can cut the pins down making the pieces come closer. the same feature is actually on the screw. You will notice that they have channels in them for you to cut with a hack saw. It will then shorten the screw and allow you to install the lock in a 35mm door. I've placed some photos at the bottom to show you the cutting guides.

If you need more advice or information, please let us know.

Thank you Eric 

noticed the notches but didn’t want to cut until I was sure that was the correct thing to do.
