Details

The Keystone S/K-90 is a standard duty cavity wall lintel, measuring 3750mm in length, specifically engineered to support openings in walls with cavity widths of 90 to 105mm. This lintel is a practical choice for builders, site managers, and contractors seeking reliable structural support for doorways and window openings. Please note that lintels must be propped during installation to maintain safety and ensure correct load transfer.

Application

This lintel is commonly used in traditional cavity wall construction where blockwork is built tight against the inner face of the lintel. It provides essential support above openings such as windows and doors, distributing loads evenly across the structure. A mortar bed should be placed on top of the blockwork before laying floor units to ensure proper load distribution. Ideal for new builds, extensions, and refurbishment projects where standard duty support is required.
