Description
The Carbine Window Multi Bolt 3 Dial Combo (CC-MB-BL) delivers a versatile, key-free physical security solution engineered to protect residential perimeters and high-traffic domestic window frames. Fabricated with a heavy-duty zinc alloy housing and an integrated three-dial mechanical combination layout, this surface-mounted barrel bolt eliminates the vulnerabilities and operational hassle of lost physical keys. It serves as an ideal security upgrade for residential windows, patio doors, and multi-frame properties requiring affordable, reliable protection against opportunistic forced entry attempts.
Designed for adaptable architectural integration, this low-profile black combination multi-bolt natively accommodates both metal and timber window frame profiles. The mechanical combination assembly is supplied complete with three distinct security bolts tailored to fit unique sill dimensions and window types, allowing the bolt to be locked securely through either a front or side projection. This self-contained hardware kit is purpose-built for straightforward residential installation, providing cost-effective property protection that aligns cleanly with modern home security and window hardware standards.
Technical Design & Mechanical Functionality
Keyless Combination & Security Casing
- Key-Free Security: Outfitted with a secure 3-dial mechanical combination lock array to eliminate physical key management or key loss entirely.
- Wear-Resistant Housing: Cased within a premium zinc alloy housing and selector dials engineered to resist long-term operational wear, physical weathering, and forced distortion.
- Code Reset Protection: Supplied with a dedicated code-resetting pin tool, allowing rapid and secure combination changes directly on the chassis body whenever security access needs to be restricted.
Fitment Geometry & Multi-Frame Adaptability
- Frame Compatibility: Versatile mechanical layout engineered to mount cleanly onto both metal aluminium extrusions and traditional wooden window frames.
- Projection Versatility: Modular locking design permits the hardened bolt to anchor successfully through either a straight front projection or a right-angle side projection path.
- Tri-Bolt Hardware Package: Packed complete with 3 separate security bolts of varying lengths and shapes to accommodate distinct window jamb clearances and structural frame variations.
- Screw Hole Installation Notice: This hardware layout features a specialised footprint configuration and will not retrofit screw directly into standard legacy multi-bolt screw hole configurations, requiring a fresh face installation prep.
