Crosby® SL-150 Slide-Loc™ Hoist Ring

Crosby® SL-150 Slide-Loc™ Hoist Rings sit between a standard eye bolt and a full swivel hoist ring in both capability and price. This 1/2" ring installs without tools - slide the lock to engage, check the red QUIC-CHECK® mark, and lift at full rated capacity at any angle up to 90°. The bail swivels 360° to align automatically with the direction of pull.

Why Choose the Crosby® SL-150 Slide-Loc™?

For fabricators, OEM manufacturers, and operations buying lifting points in volume, the SL-150 delivers the angle-rated safety that eye bolts can't match and the tool-free installation speed that full hoist rings can't match-at a price point between both.

Patent-Pending Slide-Loc™ Mechanism

• Tool-Free Installation: Thread the bolt down by hand and slide the lock to engage-no torque wrench needed. Installation takes seconds and is repeatable every time.
• QUIC-CHECK® Visual Indicator: A red mark confirms the Slide-Loc™ is properly engaged and the ring is ready to lift. A fast, reliable go/no-go check visible in any lighting condition.
• Larger Eye Opening: The oversized bail opening makes hook attachment faster and easier than standard eye bolts in the field.
• 360° Swiveling Bail: The bail rotates a full 360° to align automatically with the direction of the lift, maintaining full WLL at any pull angle up to 90°.

Built for Industrial Strength

• Forged Alloy Steel Bail, Quenched and Tempered: The bail is forged - not cast - and heat treated for strength and fatigue resistance in demanding lifting conditions.
• Proof Tested to 2‑1/2x WLL: Every SL-150 is individually proof tested to two-and-a-half times its working load limit.
• Fatigue Rated to 20,000 Cycles: Tested at 1‑1/2 times WLL for long service life in high-cycle applications.
• UNC and Metric Thread Sizes: Available in sizes from 3/8" to 1" (0.5–3.2 ton WLL) in both UNC and metric configurations.
