4190 Snatch Block w/ Shackle
The 4190 Snatch Block uses a shackle end fitting instead of a hook, giving you a secure, pinned connection point for rigging setups where a hook isn't the right call - wrecker and tow work, tailboard block rigging, and general wire rope redirection on the job site. Like other snatch blocks, the side panel drops open so you can load wire rope into the sheave without disassembling or re-threading the block. Each size runs on a bronze-bushed sheave for smooth rotation under load and is built to meet or exceed ASME B30.26 requirements.
Common Uses
- Wrecker and tow truck rigging where a shackle connection is preferred over a hook
- Tailboard block setups and vehicle recovery
- Construction, utility, and industrial load redirection and pulling
- Rigging configurations that call for a pinned connection rather than an open hook
How to Choose the Right Snatch Block
Match the block to your wire rope diameter first, then confirm the working load limit covers your actual working load with margin to spare. Larger sheave sizes reduce wire rope wear and fatigue compared to tighter bends, so size up the sheave when your rigging allows it.

All 4190 blocks are rated to meet or exceed ASME B30.26 requirements, with a 4:1 safety factor built into the assembly break strength. That rating covers hardware design, not your specific rigging setup - confirm your full rigging chain (wire rope, shackles, connection points) is matched to your lowest-rated component, and follow applicable OSHA rigging standards and your equipment documentation for setup and inspection requirements.

Frequently Asked Questions
What's the difference between a snatch block with a shackle and one with a hook?
A shackle end fitting connects with a pin, giving a more secure, less likely-to-disengage connection than an open hook. Choose a shackle version when your rigging point calls for a pinned connection or your application discourages open hooks.
What does ASME B30.26 compliance mean?
ASME B30.26 covers design, construction, and marking requirements for rigging hardware like shackles and blocks. Meeting it means the hardware is built to that design standard; it doesn't certify your specific rigging setup or substitute for your own inspection and load calculations.
Why does the sheave use a bronze bushing?
The bushing supports the sheave as it rotates, keeping the wire rope moving smoothly and reducing wear on both the rope and the block compared to a bare pin.
How do I know which working load limit I need?
Identify the maximum load your rigging setup will actually pull or support, then choose a block with a WLL that provides margin above that figure. Never load a block at or beyond its rated WLL.
Does the 3/4" size come in more than one sheave option?
Yes, the 3/4" wire rope model is available with either a 6" or 8" sheave. The larger sheave option can reduce wire rope wear on tighter rigging configurations — check the product page for load ratings specific to each sheave size.
