Cylinders / Lock Barrels

About Cylinders

Cylinder locks (also known as  profile cylinder locks or barrels) are used in conjunction with another locking mechanism such as a padlock, cylinder lock case, nightlatch or most commonly UPVC door locks.  There are many types of cylinders, the most common being Euro Profile Key & Key Cylinders (also known as Double Cylinders), Euro Profile Key & Thumb Cylinders and Rim Cylinders. We also have a range of Oval, Swedish and Screw In Cylinders.
