The Springlock fastening, designed and patented for use with pre- or post-stressed concrete cross ties and long welded rails, comprises a steel stirrup cast into the sleeper body, a spring-steel vee-clip, an insulator and a heel block. The last two items are precision-injection mouldings in thermo-setting plastic materials. The stirrup is an accurate pressing made in Corten steel to resist corrosion, and the vee-clip is hardened and tempered to ensure a constant and consistent grip loading. Insulators are positioned on the rail feet, the vee-clip is slipped in beneath the stirrup by hand, the heel of the clip is then raised and lowered on to the heel block. The whole procedure is quick, no further adjustments are needed.
