Details

The Keystone RB/K-90 Standard Duty Ringbeam Lintel is a specialist structural component designed for use in cavity wall systems incorporating integral concrete ring beams. At 900mm in length, it provides dependable support for openings such as windows and doors, making it a practical choice for builders and contractors focused on robust, code-compliant construction. Please note that the lintel must be fixed to the ring beam using M16 anchor bolts at 400mm centres to ensure structural integrity.

Application

This lintel is specifically intended for cavity wall builds where a concrete ring beam is incorporated as part of the structural framework. It provides a reliable bearing surface above openings, distributing loads safely across the cavity. Installation requires bolting the lintel to the ring beam at specified intervals, making it suitable for standard-duty applications in residential and commercial projects. Variants in the RB/K range accommodate different cavity widths, allowing flexibility depending on wall construction requirements.
