Type BR Rail Clamp

Standard rail clamp, with flat top, used for securing low speed rail, with either parallel or tapered flanges, to steel beams or concrete.

View technical specification


The Type BR rail clamp is used for securing low speed rail with either parallel or tapered flanges up to 8°. 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. Can also be used to connect low speed rail to concrete with the use of a suitable anchor device for the torque values shown below. Manufactured from malleable iron with zinc plated or hot dip galvanised finish to provide high performance and anti-corrosion protection.

Features & Benefits

  • Simple cost effective solution.
  • For low speed rail applications only.
  • Flat top allows the bolt head or nut to rotate on a hardened washer.
  • For parallel and tapered flanges up to 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

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.


  • Manufactured from malleable iron to BS EN 1562.
  • Available with zinc plated or hot dip galvanised finish.
