Crosby Hooks
All Crosby Shackles, except for G-2160’s incorporate markings forged into the product which address an easy QUIC-CHECK ® feature. Angle indicators are forged into the shackle bow at 45° angles from vertical. These are utilized to quickly check the approximate angle of a two-legged hitch or quickly check the angle of a single leg hitch when the shackle pin is secured and the pull of the load is off vertical or side loaded, thus requiring a reduction in the working load limit of the shackle.
