Details

The Keystone S/K-90 is a standard duty cavity wall lintel designed specifically for openings in cavity walls with a cavity width of 90-105mm. Ideal for builders, contractors, and site managers, this lintel provides dependable structural support where strength and reliability are essential. Please note, proper installation including temporary propping is recommended to ensure safety and build efficiency.

Application

This lintel is typically used to span openings such as windows and doors within cavity wall constructions. It supports the masonry above these openings, transferring loads safely to the surrounding structure. The lintel works best when blockwork is constructed tight against its inner face, and a mortar bed is applied atop the blockwork before laying floor units to distribute loads evenly. Its standard duty rating makes it suitable for many residential and commercial projects where moderate load-bearing is required.
