Catnic BHD100 Box Lintel Internal Wall Heavy Duty is a galvanised steel lintel designed for heavy duty internal wall applications. Built to support solid single-leaf internal or external walls, it provides full structural loading at installation. The staggered slot pattern across its underside forms an integral plaster key, reducing heat loss and improving finish quality.

Available in spans from 750mm to 4800mm, this lintel weighs approximately 30,820g at 3000mm and offers superior long-term performance thanks to its powder-coated, corrosion-resistant finish.
