As a leading manufacturer and exporter of SKL tension clamps, we ensure exceptional electric insulation of the rail on its support. These clamps maintain the rail's position elastically both vertically and transversely, featuring a support table, projecting shoulders, an interposed pad, and an insulating clip. The clip incorporates a body that works with the shoulders and a nose portion that bears against the rail flange. It includes at least one elastically yieldable strip and fastening equipment that passes through apertures in the clip body and strip.
Our boltable elastic rail clips offer high permanent clip strength, ideal for rail construction with concrete sleepers. Available in diameters from 13mm to 15mm, they range from SKL1 to SKL30.
