Crosby L-320A Alloy Eye Hoist Hook

Overview: Crosby L-320 alloy eye hooks are high-strength, load-rated hooks for demanding lifting applications, with Working Load Limits (WLL) from 1 to 60 tons. All models feature QUIC-CHECK® deformation and angle indicators for safer inspections and proper load alignment. The alloy L-320 series has a distinctive gold finish, while the painted carbon steel S-320 version, finished in red, is available by special order only and not sold on.

Latch Kits Included: Unlike older Crosby hooks which were sold without a latch, all L-320 alloy hooks now ship with the appropriate latch kit pre-installed at no extra cost. Replacement latch kits are also available if needed.

Why These Hooks Stand Out: Every hook is fatigue-rated to 20,000 cycles at 1.5× WLL and proof-tested to 2.5× WLL for 3/4T carbon through 22T alloy, or 2× WLL for 20T carbon through 60T alloy. Each hook undergoes chemical analysis and tensile testing for material verification, ensuring consistent performance. Alloy versions deliver higher strength-to-weight ratios for heavy-duty lifting.
