Sliding door locks can be hard to find. They don’t work the way normal locks do, needing some kind of hooking mechanism to prevent doors from being prised apart. A single throw-over hook does the job but it’s not hard to defeat if you are a bad guy
Sugatsune’s 7810K sliding door lock has two reciprocating catches that engage up and down to prevent interference with a lever. Security is enhanced by using dimpled million keys, modern high security keys that have up to a million variations. It is also available in a standard door version with a normal lock bolt and million key in three finishes.
Security can be a real pain in a larger development where contractors have to have their own keys to do their jobs. Another innovation from Sugatsune is what they call a ‘Construction Key System’ where each lock is provided with three keys, A, B and C. Key B overrides and cancels Key A and Key C overrides and cancels key B. So during a project contractors can be given keys which subsequently become invalid and in the event of key theft, keys can be changed without changing the lock cylinder.
The keys themselves are million keys too, so the days of finding that one key fits another door are long gone.
Most cabinet locks spend their lives in cosy interiors protecting top drawer contents for important executives. The 3810S is a lock apart, designed for work in wet or corrosive environments. It’s made from stainless steel throughout, including the keys and cylinder which are usually made from brass. It’s perfect for a process or manufacturing application where humbler locks would turn green and cease functioning.
