Details

The Keystone BOX/K-100 is a solid wall box lintel designed specifically for internal openings in 100mm wide masonry walls. Suitable for builders, contractors and site managers working on standard load applications, this 750mm lintel provides dependable support for wet masonry during construction. Please note lintels must be installed with a minimum 150mm bearing at each end, bedded on mortar for correct load distribution.

Application

This box lintel is ideal for supporting brick or blockwork above internal doorways and openings where wall thickness ranges from 100mm to 215mm. Its design allows it to carry the full weight of wet masonry as soon as it is laid, making it well suited to standard duty structural requirements on residential or commercial builds. To ensure safe and efficient installation, propping the lintel during construction is strongly advised.
