  • Built-in Plaster Key
  • Built-in DPC
  • Integral Insulation
Standard Lengths (mm) SWL (kN) 1:1/19:1 Weight (kg/m) Nominal height 'h' (mm)
900 - 2700 60 16 232
2850 - 3000 55 15.95 232
3300 - 3900 50 19.4 232

    • The SWL (safe working load) is based on the total UDL (uniform distributed load) over maximum span using 150mm end bearings.

    • To achieve the CH & CX loading figures indicated, lintels must be built-in as illustrated, ensuring that the blockwork infill is well-jointed during construction and compatible with the strength of theæmasonry above.

    • When using the Catnic CH and CX Open Back ranges with concrete floors, always ensure that the blockwork is built tight against the inner vertical face, and that a mortar joint is added to the top of the blockwork so that the floor units have an even spread over the inner flange of the lintel.
