A mortise lock forms the core of every door. In environments such as laboratories, changing rooms and cleanrooms, locking systems must be more than just functional. They need to be hygienic, long-lasting and easy to maintain. With expert guidance and ready-to-install products, Kupan ensures that every mortise lock is immediately ready for use.
A mortise lock is a type of lock that is built into the door itself, unlike a surface-mounted lock that is attached to the outside. The mechanism consists of a lock case with a latch and a deadbolt, operated by a door handle or key. Thanks to its compact design, the mortise lock is neatly concealed while still providing a secure and reliable closure. In environments where cleanliness is essential, this type of lock is ideal due to its covered installation and smooth finish.
Not every mortise lock is suitable for the same application. A lock for an interior door requires different properties than one designed for exterior use. Interior doors in offices or sanitary areas mainly require a smooth locking mechanism with a focus on hygiene. Exterior doors, on the other hand, need extra protection against moisture and temperature fluctuations. Stainless steel 316 lock cases, such as those from NEMEF and DOM, resist corrosion and are highly suitable for humid environments or spaces where hygiene is critical.
Kupan’s range includes various mortise locks, such as latch locks, vacant/engaged locks (V+B), WC mortise locks and magnetic variants. Many of these locks feature a stainless steel faceplate or lock case, making them ideal for damp and hygienic environments.
Replacing a mortise lock is easier than you might think. First, remove the door handle and pull the old lock out of the mortise. Then slide the new lock into the same position, after which the handle and key escutcheon can be reattached. Kupan’s mortise locks are designed for easy installation, allowing you to achieve a clean result without specialized tools.
Choosing a NEMEF mortise lock or a DOM Magnetic line means choosing reliability. Both brands are known for their stainless steel faceplates, long service life and ease of use. Kupan typically delivers these locks directly from stock and assists in selecting the right version. The materials used ensure that the locks withstand moisture, temperature changes and intensive use.
