Extended Door Lock Cylinder & Tube Extensions

Having a reliable and secure door lock is essential for any home or commercial building. At Keeler Hardware, we understand the importance of having a functioning door lock, which is why we offer a wide range of products to upgrade, repair or replace your existing locks. 

A popular lock accessory is the door lock extended cylinders & cylinder extensions. This ingenious solution from our night latch and deadlock collection allows you to extend your existing cylinder without having to replace the entire lock set.

These extensions are especially useful if you have a thick or oversized door that requires a longer cylinder. They also come in handy when installing a new door handle or knob set that may have different requirements than your current lock.

Cylinder Extensions For Locks

One of the main reasons for using door lock extended cylinders is their ability to fit a variety of locks fitted to doors thicker than 50mm or greater. This can be helpful when installing locks on exterior doors, as these often tend to have thicker frames for added security. With a traditional lock cylinder, the key may not be able to fully turn due to the thickness of the door, making it difficult or even impossible to unlock. However, with a cylinder extension, the key is able to reach deeper into the lock mechanism and successfully open the door. 

Extended Cylinder Locks One Way

Our extended cylinders come in various sizes and finishes to suit different types of doors and locks. These locks are designed with a one-way mechanism, meaning they can only be unlocked from the side where the key is inserted. This added security feature makes them ideal for external doors or any area that requires maximum protection against break-ins. Our extended cylinder locks are made with high-quality materials and undergo rigorous testing to ensure their durability and reliability.

Trust us at Keeler Hardware for all your door locking needs.
