UPVC doors, which are doors made of unplasticized polyvinyl chloride, are often equipped with multi-point locks. These locks have multiple locking points along the length of the door that engage with the door frame when the lock is activated. This provides increased security compared to a single-point lock.
There are several types of multi-point locks that can be used on UPVC doors, including latch locks, deadbolt locks, and hook locks.
Latch locks are the most common type of lock used on UPVC doors. They have a latch bolt that is operated by a handle and a deadbolt that is operated by a key. The latch bolt secures the door in the closed position, while the deadbolt provides additional security by preventing the door from being forced open.
Deadbolt locks have a single bolt that is operated by a key. They are typically used in combination with a latch lock to provide additional security.
Hook locks have a series of hooked bolts that engage with the door frame when the lock is activated. They are often used in conjunction with a latch lock to provide additional security.
Other types of locks that can be used on UPVC doors include cylinder locks, which are operated by a key, and lever handle locks, which are operated by a handle.
