Introduction
Locks are essential for the security of our homes, offices, and other spaces. They protect property, ensure privacy, and give peace of mind. However, installing a standard lock is not always feasible — especially when space is limited. This is where narrow locks, also called aluminium profile locks, come into play. Designed for doors and windows with restricted cavity space, narrow locks provide a secure, practical solution without compromising style.
In this article, we explore narrow lock designs, materials, types, and why they are the perfect solution for limited spaces.
Why Narrow Backset Design Matters
Traditional mortise locks are commonly used in wooden doors, armored doors, and other heavy doors. Their backset usually ranges from 40–50 mm, requiring ample internal space. Aluminium doors, however, have narrow profiles, making standard mortise locks unsuitable.
Narrow backset locks solve this problem. Their compact design reduces the lock body size, allowing installation in tight aluminium or narrow door frames. This design also reduces weight, making the locks cost-effective and easy to handle.
Narrow locks are widely used in:
- Modern aluminium doors
- Sliding doors or windows
- Office and commercial buildings
- Residential spaces with limited internal door cavity
Materials Used in Narrow Locks
Narrow locks must be compact yet durable. Material selection ensures performance and longevity.
Component | Typical Material | Notes |
Latch | Zinc alloy / Stainless Steel 304 | Strong, corrosion-resistant, cost-efficient |
Deadbolt | Iron / High-grade Steel | Maximum security, resists forced entry |
High-quality materials guarantee reliability even in compact designs, providing confidence to installers, architects, and end-users.
Classification of Narrow Locks
Lock Type | Application | Description |
Roller Lock | Rolling shutters, commercial doors | Secures moving panels; compact and smooth operation |
Deadbolt Lock | Aluminium residential & office doors | Provides strong security; fits narrow aluminium profiles |
Sash Lock | Windows, sliding doors | Secures movable panels; ideal for aluminium and uPVC frames |
