Sliding patio doors are a common way in for burglars, especially older doors with worn locks or lift-out panels. Our patio door range covers replacement locks, hookbolts, gearboxes, handle sets, cylinders, rollers, tracks and extra security such as patio door bars.

We stock parts from Mila, Fuhr, Fullex, Adams Rite, Era, Yale, Hoppe, Trojan, Siegenia, Schlegel and Lockmaster, in uPVC and aluminium fittings. Most patio parts are specific to the door system, so check the brand stamped on your lock or faceplate and measure the old part before ordering. Upgrading the cylinder to a TS007 3-star or anti-snap model is one of the cheapest ways to improve security. Price match guarantee on every product.

Buy it, and we can fit it. We are not just an online shop: our own locksmith engineers can install what you order, so you get the right product and a proper installation from one company. Call 0333 305 2967 or ask about fitting when you order.
