The Catnic CH110/100 Heavy Duty 110mm Cavity Lintel is designed for masonry cavity walls with a 110–125mm cavity, a 100–115mm inner leaf and a 100–102mm outer leaf. Its open-back steel profile allows masonry to be built up continuously on both leaves, while integral insulation, a built-in DPC and plaster key provide practical construction benefits. We supply 11 lengths from 900mm to 2400mm, with safe working loads of 32kN, 48kN or 45kN depending on length.

Where to use a Catnic CH110/100 lintel

The CH110/100 is intended for heavy duty masonry cavity-wall construction with a cavity width of 110–125mm. It supports specified masonry, timber floor and roof loads where the selected lintel's safe working load is sufficient.

Its open-back profile allows masonry to be built continuously on both leaves and is suitable for fair-faced inner leaf masonry.

Choosing the correct CH110/100 length

Catnic's published loading figures use nominal 150mm end bearings at each end. As a general starting point, add 300mm to the clear structural opening width to allow for these bearings.

For example, a 1200mm structural opening would normally require a 1500mm lintel, with 150mm bearing at each end. The selected lintel must also have sufficient safe working load for the loads above.

Installation and concrete floor support

Check the cavity width, masonry leaf dimensions and supporting wall construction before installation. Follow Catnic's guidance for end bearings, temporary propping and restraint.

When using Catnic CH and CX open-back lintels with concrete floors, the blockwork must be built tightly against the inner vertical face of the lintel. Catnic also requires a mortar joint at the top of the blockwork so that the floor units distribute their load evenly over the inner flange.

For standard duty applications with the same cavity dimensions, compare our Catnic CG110/100 Standard Duty Cavity Lintel.

For extra heavy duty requirements, we also supply the Catnic CX110/100 Extra Heavy Duty Cavity Lintel.
