Where Rim Cylinders Work Best
Surface-Mounted Security for Homes, Flats & Retrofit Projects
Rim cylinders are most commonly used in residential properties for front and back doors with night latches. They're especially popular for older properties, flats, and shared entrances where secondary locks are common. Designed for ease of fitting, they can be upgraded without disturbing the internal lock body — a great choice for homeowners, landlords, or maintenance teams handling multiple properties.
As part of our extensive Architectural Ironmongery range, they can be paired with our Accessories, Door Furniture, or Window Furniture collections for a complete finish.
