Profile: A. Kenrick & Sons offers products and services such as window doors, door hardware, furniture fittings and sub contract. We provide door hardware such as Excalibur door lock, lockmaster door lock and door hinges. The design of our lockmaster is such that the rollers begin to compress the door before the high security hooks or anti-lift bars engage with their keeps. This reduces wear on the lock and allows a smooth operation. Our twinwheel castors are used for office applications and are available in 3 standard colours. There is also a wide range fitting to suit steel, wood and chipboard.
