The C990A provides effective security through simple and reliable operation, at a very competitive price. This popular pushlock is used primarily to secure sliding wooden doors. It is sturdily constructed from alloy parts and uses a five disc tumbler mechanism. The die-cast housing and flange are finished in bright chrome plate.

This pushlock is suitable for frequently used applications; the key can be inserted into the lock either way up. An unusual feature for a pushlock is the facility to withdraw the key in a fully unlocked position, preventing locking, perhaps where frequent access is required at certain periods. When secure locking is needed at other times, perhaps overnight, the key may be returned to the ‘push to lock’ position. A cylinder rose is supplied, as standard, to improve the aesthetics of the lock when mounted. Supplied keyed alike or keyed alike in groups with two reversible keys per lock, as standard.
