Description The Screw Pin Theatrical Shackle may be used in side-loading applications with required reduction of Working Load Limits. Unlike Bolt-Type shackles, they are not to be used for long-term installations. Do not use any Screw Pin Shackles with a load that may rotate the pin. Theatrical Shackle Sizes: 3/8” through 3/4” Capacities: 1 through 4-3/4 metric tonnes. Forged – Quenched and Tempered, with alloy pins. Working Load Limit permanently shown on every shackle. Flat black baked on power coat finish. Fatigue Rated. Industry leading 6 to 1 design factor. Screw pin anchor shackles meet the performance requirement of Federal Specification RR-C-271F Type A, Grade A, Class 2, except for those provisions required of the contractor. Meets the performance requirements of EN 13889:2003. Meets or exceeds all requirements of ASME B30.26 Failure to read the proper warning and application information may result in serious injury or death.

For permanent or long-term installations, Crosby recommends the use of bolt type shackles. If you choose to disregard Crosby’s recommendation, the screw pin shall be secured from rotation or loosening (Page 90, Crosby Catalog 2016). Screw pin shackles can be used for applications involving side-loading circumstances. Reduced working load limits are required for side-loading applications. While in service, do not allow the screw pin to be rotated by a live line, such as a choker application. * Pick and Place application: Pick (move) a load and place as required. Tighten screw pin before each pick. QUIC-CHECK® INFORMATION All Crosby Shackles, with the exception of 2160, 2169, 2170, 252 and 253 styles incorporate markings forged into the product that address an easy to use QUIC-CHECK® feature. Angle indicators are forged into the shackle bow at 45 degree* angles from vertical. These are utilized on screw pin and bolt type shackles 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 (side loaded), thus requiring a reduction in the working load limit of the shackle. *Note – Though technically incorrect, A Shackle is sometimes referred to as a Clevis
