Patio door handle and lock

A home owner from Wheeling, IL says:
We have not been able to find this door handle and lock to fit our patio door. The door is 1 inch in thickness and everything we have tried is too wide for the door.

This door it's about 20 years old.

Hello,

Take a look and compare the 82-055 with 3-1/2" installation holes, as well as the 82-003 with 3-15/16" installation holes, to your original handle set. The 82-003 comes with installation screws for 1" thick doors and the 82-055 can accommodate doors up to 1-1/2" thick. It would be a good idea to hold onto your original installation screws just in case you need to reuse them. Thanks for posting!
