The Gator Mortise Wrench is made especially for those times when you just can’t use pliers on a mortise cylinder. The low profile construction will allow you to grip the smallest edge on a cylinder. As long as it’s not deeply recessed into the door, you should be able to use the Gator Mortise Wrench (P/N MW053B) to quickly remove even the most stubborn mortise cylinder without damage. Made in the USA
