Narrow Nightlatch 40mm with 5 Pin Cylinder Secure Door Lock Compact Design for Home and Office Entry

In the world of home security, one size rarely fits all. For many modern homes and period properties featuring glazed front doors or slim timber frames, a standard 60mm lock is simply too deep to install. The narrow nightlatch 40mm is the definitive answer to this architectural challenge.

Engineered specifically for doors with limited “stile” space, this narrow nightlatch 40mm provides robust perimeter protection without requiring extensive modifications to your woodwork. Whether you are a homeowner looking to upgrade a back door or a contractor securing an office entry, this compact unit offers the perfect blend of a reduced footprint and professional-grade security. By choosing a short-backset model, you are ensuring that even the most delicate-looking doors are backed by a formidable mechanical defense.

The primary appeal of this narrow nightlatch 40mm lies in its space-saving geometry. Traditional rim locks often clash with glass panels or decorative moldings, but this 40mm version sits comfortably on narrow sections of wood. Every unit in our narrow nightlatch 40mm collection features a precision-cast body that houses a sophisticated internal spring mechanism. This ensures the latch operates with a crisp, audible click every time the door is pulled shut.

Why this Slim-Stile Lock is a Security Essential

Security starts with the cylinder, and every set we supply comes equipped with a high-performance 5-pin brass barrel. This sophisticated pinning system provides significantly better resistance against lock-picking and manipulation than basic 3-pin alternatives.

Furthermore, the internal body features a multi-functional snib. This allows the user to either deadbolt the latch from the inside for extra nighttime security or hold the bolt back temporarily for convenience when moving items in and out of the building. The versatility of this compact rim lock makes it an incredibly user-friendly option for busy households and commercial settings alike.
