It doesn’t happen often but when it does you’re stuck trying to make a standard cylinder reach beyond its proper length. The door is thicker then normal and you need to find a way to fit a cylinder to the door.

Up until about the late 60s, Corbin, Russwin, McKenney and others made adjustable cylinders. After they ceased making those cylinders if you had a door that was an odd thickness you had to order specially made cylinders, which were expensive.

MAJOR MANUFACTURNG has come out with a cylinder extension kit and drill guide that will allow you to custom make odd-ball length cylinders right on your truck or in your shop!

This 7-minute video shows you how they work and how easy it is to solve what otherwise could be a real problem: especially with some of the new and thicker doors being manufactured today.
