Details

The Keystone S/K-90 is a standard duty cavity wall lintel, specifically engineered to support openings in walls with cavity widths between 90 and 105mm. At 4200mm long, it is well suited for larger spans commonly encountered on site. This lintel is a dependable choice for builders, contractors, and site managers requiring reliable structural support for blockwork openings.

Application

This lintel is designed for use in cavity wall construction, supporting brick or blockwork above window and door openings. It is essential that blockwork is built tightly against the lintel’s inner face to maintain structural integrity. A mortar bed should be placed on top of the blockwork before laying floor units to ensure even load distribution. For safety and to expedite construction, lintels should be propped during installation.
