Type CF High Slip Resistance Clamp
High slip resistance girder clamp designed to hook over the flange of beams, angles and channels to connect opposing steel sections.
Overview
The Type CF girder clamp is used to achieve a fast connection where the flanges of steel beams, angles or channels are opposing each other. The high slip resistance clamp is designed to be used in a two clamp configuration and to hook over the edge of the flange. A bolt, threaded rod or other threaded item is used to connect the two clamps and complete the assembly. Type CF can also be combined with our other HSR girder clamp products to make connections from a flange edge to the flat face of a steel section. Manufactured from SG iron with a hot dip galvanized finish to provide high performance and anti-corrosion protection.
Features & Benefits
- Hooks over flange edge to allow connection of opposing sections.
- High slip resistance for tensile, frictional and combined load applications.
- Suitable for parallel and tapered flanges up to and including 10°.

Location & End Plates
Location plates are required when securing two sections together with clamps attached to the upper and lower sections with both clamps directly opposing each other. The plate is positioned between the two sections to hold the bolts at the correct centers and should be fabricated to the dimensions shown in the datasheet.
End Plates should be used when clamps are attached to the supporting section only. The End Plate holds the bolts at the correct centers and should be fabricated to the dimensions shown in the datasheet.
