High slip resistance girder clamp designed to hook over the flange of beams, angles and channels to connect opposing steel sections.
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
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.

Faster to Install
No drilling or welding!
Reasons to choose Lindapter
Save time and money
Clamping two steel sections together avoids time-consuming welding or conventional drilling and bolting.
On-site drilling and welding is avoided, removing the need for hot work permits and encouraging safer site conditions.
Lindapter clamps are manufactured from high strength materials to resist high load requirements and harsh environments.
Industry leading approvals
Lindapter has earned a reputation synonymous with safety and reliability, gaining multiple independent approvals.
Quickly align steel sections by sliding the section into the correct position before tightening the Girder Clamp to complete the installation.
Free connection design
Lindapter’s experienced Engineers can design a bespoke connection based on your specific requirements free of charge.
