Door security is important in this day and age, therefore it makes sense to use door hardware brands that you can trust and rely on. Our selection of door handles are supplied from many leading brands such as Avocet, Hoppe, Mila, Roto, Sobinco and Winkhaus. We categorise these handles into lever/lever, lever/pad and lever/fixed.
This is a special type of locking mechanism that is fitted to the full length of a door. It features multiple locking points made up of a central deadbolt pin and works together with various bolts and hooks that lock into place when the handle is operated. These locking points provide increased security for your home whilst offering improved seal compression, and are available to suit all types and styles of doors.
A door cylinder is a form of pin-tumbler lock, usually fitted to UPVC doors and commercial doors. The cylinder fits into the door and can even be located underneath the door handle. When the key is turned, the pins operate a deadlocking mechanism inside the door. The main advantage of a cylinder lock is that can be easily replaced without needing to remove any other bolted door hardware.
There are a few different types of door handle that can be fitted to a uPVC door or composite door. Lever-Lever door handles consists of a pair inline handles fitted to either side of the door.

I was after a replacement bottom door seal for my double glazed back door that had been installed 5 years ago. I had no luck with the original installer or searching online. Then after taking a picture of the end of the seal and doing a picture search up popped a picture from DG Supply Line. They had the exact seal I was after. It was easy to place an order, they had competitive pricing , and the order was delivered a few days later. So an excellent hassle free service.
