Replace a HUGE Mortise Cylinder with a Normal One!

Have you ever run into a humongous mortise cylinder like the image below? That mortise cylinder is an inch and a half in diameter wide and I don't know of any manufacturers today that make a mortise cylinder this big. Now the problem is that these inch and a half mortise cylinders exist in the world today even though they’re not made anymore. If you’re going to have to work on one, here are real solutions to real problems when dealing with this mortise cylinder.

The Solution

Since an inch and a half in diameter wide cylinders are not made, you won’t be able to buy one to replace it. So, let's focus on what is made. What is made is the standard inch and eight length with one inch diameter cylinder.

 

But if you were to put the standard cylinder into inch and a half hole, guess what's going to happen? It's not going to screw in, unless you have the adapter ring.

 

HOW TO USE

Attach the adapter ring to the standard mortise cylinder. Align the Allen screw to the cutout and screw it down. The adapter ring will turn the standard mortise cylinder into an inch and a half.

After that, take the cylinder with adapter ring and screw it into the inch and a half hole.

 

THE TAIL PIECE

Depending on the situation, the tail piece will be a problem. The tail piece from the standard mortise cylinder with adapter ring is smaller compared to the tailpiece of the inch and a half. So, you may have to modify the tail piece. You may have to take off the old existing one that you're replacing, and modify it to fit on the smaller one but the good news is most of your problem is going to be solved by the adapter ring. So if you live in an area that tends to have a lot of these big cylinders, stocking one of these rings might be good. But other than that, at least you know they're going to be available. 

 

The adapter ring is handy thing to know about. Put your thoughts by commenting to our YouTube video. Make sure that you include the #LockBoss to automatically get entered in to win one of five free prizes we giveaway each week on YouTube. Thank you, and we'll see you next time.
