Type BR Girder Clamp
Standard girder clamp, with flat top, used to quickly connect steel beams with either parallel or tapered flanges up to and including 8°. The full width tail allows the clamp to span slotted clearance holes.
Overview
The Type BR girder clamp is used to quickly connect steel beams with either parallel or tapered flanges up to and including 8°. The full width tail allows the clamp to span slotted clearance holes. It has a flat top to allow the bolt head or nut to rotate on a hardened washer and can also be used with studs, tie rods or J-bolts. The skirt on the underside of the clamp abuts the edge of the beam flange and prevents the clamp rotating during installation. Manufactured from malleable iron with zinc plated or hot dip galvanized finish to provide high performance and anti-corrosion protection.
Features & Benefits
- Simple cost effective solution.
- Flat top allows the bolt head or nut to rotate on a hardened washer.
- For parallel and tapered flanges up to and including 8°.
- Contact Lindapter to ensure suitability of the component for application.
- Please ensure the anchor device is suitable for the torque value in the data table.

Tail Lengths & Packing Pieces
The clamp is available in two tail lengths, Short or Medium and can be used with Lindapter packing pieces to increase the clamping range. Choose the correct combination of tail length and packing pieces to suit a specific flange thickness. Download datasheet for selection table.
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.
Properties
- Manufactured from malleable iron to BS EN 1562.
- Available with zinc plated or hot dip galvanized finish.
