Rigging Hooks and Attachments
Every overhead lift ends at the hook. Holloway Houston stocks the full hook line - self-locking, sling, swivel, grab, and foundry hooks - from Crosby, Gunnebo, Cartec, and other OEMs, sized from light-duty chain connections through heavy-lift master hooks. Same-day pickup available on in-stock sizes.
Rigging Hooks & Hardware
Every lift ends at the hook. As the primary connection point, your rigging hooks must be matched not only to the weight of the load but also to the type of sling (chain, wire rope, synthetic) and the operational environment.
Holloway Houston Inc. (HHI) is a premier distributor for the biggest names in the industry: Crosby, Gunnebo Industries, Yoke, Carcano, and Cromox. Our inventory covers every configuration imaginable, from fractional-ton miniature hooks to massive 200-Ton heavy-lift hoist hooks. We also stock the critical spare parts Latch Kits, Load Pins, and Triggers to keep your gear compliant.
The Hook Ecosystem: Choosing the Right Tool
1. Sling Hooks (Eye & Clevis)
The standard termination for most chain and wire rope slings.
- Clevis Hooks: Connect directly to the chain links via a load pin. We stock Crosby and Gunnebo Grade 100 clevis hooks that eliminate the need for a connecting link.
- Eye Hooks: Designed for use with wire rope thimbles or synthetic web slings (via a coupler).
- Foundry Hooks: Wide-throat hooks designed without a latch to fit over large trunnions or molding handles.
2.Self-Locking Hooks (Safety Hooks)
The safest option for overhead lifting. These hooks close and lock automatically under load.
- Gunnebo BK Series: The gold standard in self-locking technology. The latch interlocks with the hook body for maximum stability.
- Crosby Shur-Loc (S-1316): Features a large trigger for easy operation with gloves.
- Application: Prevents "roll-out" and accidental detachment, mandatory on many safety-critical construction sites.
3.Grab Hooks & Shorteners
Used to adjust the leg length of a chain sling.
- Cradle Grab Hooks: Feature a support saddle that cradles the chain link, ensuring the chain retains 100% of its Working Load Limit (WLL).
- Shortening Clutches: Innovative designs like the Gunnebo MIG allow the shortening function to be built directly into the master link, reducing weight and clutter.
4. Hoist & Shank Hooks
Replacement hooks for cranes and blocks.
- Crosby 320N Series: The industry standard carbon and alloy hoist hooks.
- Swivel Hooks: Available in Positioning (rotates only when not under load) and Bearing Swivel (rotates under load) to prevent line twist.
5. Specialty & Automatic Hooks
Designed for specific applications requiring enhanced safety, automation, or corrosion resistance.
- Weld-On Hooks: Yoke and Crosby weld-on points for excavator buckets and spreader beams.
- Elebia Automatic Hooks: Remote-controlled hooks that allow the operator to attach and release the load from a distance, eliminating the need for a rigger to climb onto dangerous loads.
- Cromox Stainless: Grade 60 stainless steel hooks suitable for corrosive or clean-room environments.
6. Swivel Hooks
- Rotating body for twist management. Browse
7. Foundry Hooks
- Wide throat for bulky industrial loads. Browse
Maintenance: Latch Kits & Spares
A broken latch is the most common reason a hook fails inspection. You don't always need to replace the whole hook. HHI stocks genuine OEM Replacement Parts:
- Latch Kits: Standard flapper latches (Crosby S-4320) and heavy-duty locking latches.
- Trigger Kits: For repairing Gunnebo and Crosby self-locking hooks.
- Load Pins: Replacement pins for clevis connections.
Why Holloway Houston
Decades of industrial rigging and lifting experience, ISO 9001 certification, same-day pickup from Houston, and multi-manufacturer inventory across five hook types. Holloway Houston also offers rigging inspection services for customers managing periodic inspection cycles on lifting hardware.
Matching a Hook to the Lift
- Sling type : chain slings pair with grade-matched hooks; synthetic slings pair with throat-width-matched hooks.
- Environment : dynamic lifts and vibration favor self-locking; controlled lifts use standard latch.
- WLL : hook rated capacity matches or exceeds sling and load assembly rating per manufacturer documentation.
- Inspection cycle : ASME B30.10 covers inspection criteria for hooks in overhead lifting.
Standards and Compliance
Rigging hooks fall under ASME B30.10 (Hooks). OSHA 29 CFR 1910.179 applies to overhead/gantry cranes; OSHA 29 CFR 1926.251 applies to rigging on construction sites.
Brands We Carry
Crosby (including Shur-Loc self-locking), Gunnebo (BK self-locking + Kito Crosby catalog), Cartec (specialty self-locking), Peerless (chain and sling hooks), and additional OEMs.
Frequently Asked Questions
Five main categories: self-locking (trigger/spring latch holds under bump), sling hooks (standard spring latch matched to chain grade), swivel hooks (rotating body for twist), grab hooks (chain shortening), and foundry hooks (wide throat for bulky loads). Specialty variants including shank hooks and eye hooks are in the Holloway Houston catalog.
Inspection programs typically look for throat opening distortion, cracks or gouges, saddle wear, damaged or missing latches, and unreadable markings. ASME B30.10 published criteria cover dimensional tolerances. Holloway Houston's rigging inspection services handle documented inspections.
Self-locking hooks are typically the match in dynamic environments — construction sites with swinging loads, platforms with vibration, applications where a bumped latch could let the sling roll out. Standard sling hooks remain appropriate for controlled overhead lifts.
