Details

The Keystone S/K-90 is a standard duty cavity wall lintel measuring 3300mm in length, purpose-built to support structural openings where cavity widths range between 90 and 105mm. This lintel is a trusted choice for builders, contractors, and site managers seeking dependable and straightforward solutions for cavity wall construction. Please note, proper installation practices such as propping are necessary to ensure optimal performance.

Application

This lintel is typically used to support window and door openings within cavity walls where the cavity width fits within the 90-105mm range. It provides the necessary strength to carry loads above openings while integrating seamlessly with blockwork and brick facings.
