Catnic CH50/100 Heavy Duty 50mm Cavity Wall Lintel

The Catnic CH50/100 is a heavy duty steel lintel for 50–65mm cavity wall construction with a 100–115mm inner leaf and 100–102mm outer leaf. Its open-back profile allows masonry to be built continuously on both the outer and inner leaves.

Manufactured from galvanised steel, the CH50/100 is supplied fully insulated and incorporates an integral plaster key and built-in DPC profile. It is designed to support typical masonry, timber floor and roof loads and is suitable for fairfaced inner leaf masonry.

Typical Applications

The CH50/100 is designed for heavy duty openings in cavity wall construction where the cavity is 50–65mm and the inner leaf is 100–115mm. It supports typical uniformly distributed masonry loads and distributed timber floor and roof loads and is suitable for fairfaced inner leaf masonry, subject to the project loading and installation requirements.

Installation & Technical Notes

150mm minimum end bearing: Catnic's published safe working load data is based on 150mm end bearings. Ensure the lintel is installed with the required bearing for the application.

Build both leaves together: Follow the manufacturer's installation guidance and ensure the masonry is built correctly around the lintel.

Concrete floors: When using the Catnic CH and CX Open Back ranges with concrete floors, Catnic states that blockwork should be built tight against the inner vertical face, with a mortar joint at the top of the blockwork so floor units have an even spread over the inner flange.

Load selection: Safe working load varies by lintel length. Select the correct CH50/100 length using the manufacturer's load/span information for the project.

Why choose the Catnic CH50/100?

The CH50/100 combines heavy duty structural support with practical cavity wall features including a built-in DPC, integral insulation, plaster key and open-back profile. It is a suitable option where a 50–65mm cavity and 100–115mm inner leaf match the project specification.
