Jason and Trilock, explained
Why Jason parts matter
Jason makes aluminium windows and sliding doors, and makes locks and handles to fit its own frames. Its lever lock handle, for example, is listed for residential sliding and stacking doors from 2008 onwards (Jason Windows shop). So the first thing we check is the style and age of your window or door, and then we fit the part made for it.
We carry Jason locks and parts in the van, so there’s usually no wait for parts.
What a Trilock is
Trilock is Gainsborough’s front door set. Gainsborough says it combines lockset, deadbolt and passage functions in one system (Gainsborough Hardware).
Bought one yourself?
Plenty of people pick up a Trilock at the hardware store and then need it fitted. We fit it, check the door closes and deadlocks properly, and, if you want one key for the whole house, rekey your other locks to match in the same visit. See lock rekeying.
Repair or replace
A stiff lever, a worn catch or a loose handle is often a repair. If a part is no longer made, we’ll tell you and show you what fits instead. We agree the price before we start, and after-hours work costs more.
