Product Information

Keystone HD/K-90 lintel, 4200mm (13ft 9in) length, designed for heavy duty cavity walls.
Supports cavity widths from 90mm to 105mm (3.5in to 4.1in) ensuring a precise fit for standard structural builds.
Constructed to carry substantial loads above openings such as windows and doors on cavity walls.
Recommended to prop lintels during installation to maintain structural integrity and speed up site work.
Blockwork must be built tight against the inner face of the lintel; mortar bedding required for even load distribution.

Details

The Keystone HD/K-90 Heavy Duty Cavity Wall Lintel at 4200mm length is engineered specifically for builders and site managers requiring a reliable lintel to support substantial loads over openings in cavity walls. Suitable for cavity widths between 90mm and 105mm, this lintel ensures a robust structural solution for demanding projects. Please note, blockwork should be built tight against the lintel’s inner face for optimal performance.

Application

This heavy duty lintel is ideal for use in cavity wall construction where openings such as windows and doors require strong load-bearing support. It is well-suited to both residential and commercial builds where cavity widths fall within the 90-105mm range. To ensure even distribution of load, a mortar bed should be applied on top of the blockwork before laying floor units. Installation is faster and safer when lintels are adequately propped during construction.
