Cabstrut concrete insert channels are manufactured from Mild Steel to BS1449-1.2:1991 and hot-dip galvanised after manufacture to SANS 121:2001 / ISO 1461:2009.

Cabstrut concrete insert channels have 38 x 15 x 21mm wide punched out lugs at 100mm centres and are filled with injected polyurethane foam to prevent any ingress of concrete into the channel openings.

Cabstrut concrete insert channels offer a practical solution for the provision of mechanical fastening into concrete walls, floors and ceilings.

Because the support capacity of any concrete insert depends largely on the strength of the concrete used, Cabstrut cannot guarantee any particular load. Recommended loading in average good concrete, with a safety factor of two, is 580 Kgs per 300mm for the P3200 concrete inserts and 460 Kgs per 300mm for the P3300 concrete inserts.

Standard lengths are 5000mm. For safe support Cabstrut concrete inserts should be at least 300mm long.
