lokkdørslåser

Lokkdørslåser, also known as mortise locks or double cylinder deadbolts, are a type of locking mechanism commonly found on exterior doors. The term "lokkdørslåser" is specific to certain regions and may not be universally recognized. These locks are characterized by a bolt that extends from the lock body into the door frame. They typically require a key to operate from both the inside and the outside, hence the "double cylinder" designation.

The primary function of a lokkdørslås is to provide enhanced security by offering a more robust locking solution than simpler spring latches. The deadbolt mechanism, when engaged, cannot be easily forced open by simply pushing or jimmying the door. The dual key operation means that a burglar cannot simply break a window and unlock the door from the inside.

Installation of a lokkdørslås usually involves cutting a rectangular pocket into the edge of the door to accommodate the lock body. The deadbolt then engages with a strike plate installed in the door frame. Variations exist in the design and complexity of these locks, with some offering features like resistance to picking or bumping. The choice of a lokkdørslås is often driven by security concerns and the desire for a reliable and durable locking system for homes and businesses.
