Details

The Keystone RB/K-50 Standard Duty Ringbeam Lintel at 3300mm length is engineered for builders and contractors working on cavity wall constructions requiring integral concrete ring beams. This lintel provides reliable structural support and is a practical choice for standard duty applications. Please note, the lintel must be fixed to the ring beam using specified anchor bolts to ensure stability.

Application

This lintel is typically used in cavity wall builds where an integral concrete ring beam is part of the structural design. It supports openings such as windows and doors by distributing loads effectively across the cavity wall. The RB/K-50 is ideal for projects requiring a standard duty lintel that can be securely bolted directly to the concrete ring beam at 400mm centres using M16 anchor bolts, ensuring robust and compliant installation.
