Yale (formerly Chubb) 8K116 Locking Bolt

The Yale 8K116 is a robust and easy-to-use surface-mounted security bolt designed to improve the protection of a wide range of doors. Ideal for securing rear entry points, the 8K116 complies with common insurance requirements that recommend key-operated locking bolts at both the top and bottom of rear doors.

This locking bolt is suitable for a variety of door types, including aluminium patio doors, wooden back doors, conventional hinged doors, and sliding doors. Unlike traditional mortice bolts, the 8K116 can be installed without the need to remove substantial timber or unhang rebated doors—making it a practical, high-security upgrade with minimal disruption.

The 8K116 is versatile and can be fitted either horizontally or vertically depending on the door configuration. Its steel locking bar provides strong resistance to forced entry, while the supplied keys ensure safe and simple operation.
