Crosby S-3319 4.5 Ton Utility Swivel Hook - 7/8" - 1-1/16" Rope

Crosby S-3319 Utility Swivel Hook – Built for Synthetic Rope. Engineered to Protect It.

Synthetic rope demands hardware that works with it, not against it. Standard hooks create abrasion points, allow rope misalignment, and accelerate wear that shortens rope service life and compromises load security. The Crosby S-3319 Utility Swivel Hook solves all of that — with a purpose-built spool and shield design that keeps synthetic rope correctly aligned, reduces abrasion at the contact zone, and protects the rope throughout the full range of motion from positioning to lift.

Spool & Shield — Rope Protection by Design

The S-3319's integrated spool and shield isn't an afterthought accessory — it's a core engineering feature. The spool maintains correct rope seating inside the hook body while the shield prevents the rope from contacting sharp hook geometry that causes accelerated wear. For utility, forestry, and construction operations where synthetic rope is a significant investment and replacement is costly and disruptive, that built-in protection directly extends rope service life and reduces operating costs over time.

Right Weight for Efficient Overhaul

The S-3319 is designed with deliberate overhaul weight — providing enough mass to ensure efficient hook positioning and descent before the lift, without adding unnecessary bulk. Available in three sizes covering 1.63 to 4.50 ton WLL and synthetic rope diameters from 9/16" to 1-1/16", each size is precisely weighted for its capacity range. Forged from quenched and tempered alloy steel to a 5:1 design factor with a proof load of 2× WLL, the S-3319 delivers Crosby-grade strength in a hook optimized specifically for synthetic rope environments.

The heavy-duty latch interlocks with the hook tip for positive load retention, with replacement latch kits available for each size.
