A heritage slam lock in the UK is a type of lock commonly used on traditional or period-style doors. It is a surface-mounted lock that automatically latches when the door is closed (slammed shut), without needing a key to lock it. The lock can be opened from the inside by turning the handle or using a thumb turn, and typically requires a key to unlock from the outside. This type of lock is popular for its convenience and traditional aesthetic appeal.
