A sliding door lock is a security device designed to secure sliding doors, commonly found in homes and businesses. These locks can be installed on various types of sliding doors, including those made of glass or wood. They work by engaging a bolt or latch that prevents the door from being opened from the outside, enhancing safety and privacy. There are different types of sliding door locks, such as keyed locks, thumb turn locks, and pin locks. Each type offers varying levels of security and ease of use. Proper installation and maintenance of these locks are essential to ensure they function effectively and provide reliable protection.
