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! |
