New anti-friction bearing design allows hook to rotate freely under load.

• Capacities ranging from 2 through 15 metric tonnes.
• Forged Alloy Steel - Quenched and Tempered.
• Proper design, careful forging, and precision controlled quench and tempering gives maximum strength without excessive weight and bulk.
• Low profile hook tip designed to utilize Crosby S-4320 or PL-N latch kit.   Simply purchase the latch assemblies listed and shown on pages 97-99. Even years after purchase of the original hook, latch assemblies can be added.
• S-3322 hooks incorporate markings forged into the product which address two (2) QUIC-CHECK features:

  Deformation Indicators -- Two strategically placed marks, one just below the shank or eye and the other on the hook tip, which allows for a QUIC-CHECK measurement to determine if the throat opening has changed, thus indicating abuse or overload. To check, use a measuring device (i.e. tape measure) to measure the distance between the marks. The marks should align to either an inch or half-inch increment on the measuring device. If the measurement does not meet this criteria, the hook should be inspected further for possible damage. Angle Indicators - Indicates the maximum included angle which is allowed between two (2) sling legs in the hook. These indicators also provide the opportunity to approximate other included angles between two slings legs.

• U.S. Patents 5,381,650 & 5,193,480 & 5,103,755 and foreign equivalents.

* NOTE: Proofload is 2.5 times the working load limit. Designed with a 4.5 to 1 design factor.
   Supplied with latch attached.
