Crosby® 2140 Alloy Bolt Type Anchor Shackles
Durham Lifting are an authorised stocking distributor of Crosby® Shackles
Durham Lifting’s Crosby® G-2140 meets the performance
requirements of Federal Specification RR-C-271G.
Bolt-Type Shackles can be used in any application where round pin or screw pin shackles are used. In addition, they are recommended for permanent or long term installations and where the load may slide on the shackle pin causing the pin to rotate. The bolt-type shackle’s secondary securement system, utilizing a nut and cotter, eliminates the requirement to tighten pin before each lift or movement of load.
Look for the Red Pin®, the mark of genuine Crosby quality.
