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.

View technical specification

Overview

The Type CF girder clamp is used to achieve a fast steelwork fixing 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 galvanised 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°.
  • Lindapter recommends the use of DTI Washers conforming to EN14399-9 with the Type CF.

Location & End Plates

These plates ensure the clamps and bolts are located in the correct position relative to the supporting steelwork. Location plates are simple fabricated items designed to sit between the two sections to be clamped together to ensure the bolts are fixed at the correct centres. End plates are simple fabricated items that are pre-welded to support frames, bracket or sections, allowing connection to the supporting structure with standard Lindapter clamps. Download datasheet for further information.
