Details

The Keystone S/K-50 Standard Duty Cavity Wall Lintel, measuring 2550mm in length, is engineered to provide dependable structural support for cavity walls with widths from 50mm to 65mm. Perfectly suited for builders, contractors, and site managers working on residential or commercial projects requiring reliable lintel performance over openings. Please note, blockwork must be built tight against the inner face of the lintel to maintain integrity.

Application

This lintel is commonly used to span openings in cavity wall constructions, including window and door frames, where a standard duty load is expected. Its design ensures even load transfer from the masonry above to the supporting structure below. For best results, a mortar bed should be laid on top of the blockwork before floor units are installed, helping distribute weight evenly. Propping the lintel during installation is recommended to maintain safety and speed up the build process.
