Crosby® McKissick® 419 Snatch Blocks with Shackle and Bronze Bushings
Crosby® McKissick® 419 snatch blocks with a shackle and bronze bushings give crews a rugged way to redirect wire rope on utility, construction, and heavy rigging jobs. This collection runs from compact 3" blocks up to 18" sheave blocks, with working load limits from 2 tons to 15 tons and wire rope ranges from 5/16" up to 1".
Each block pairs a forged steel shackle with a bronze bushing sheave, a simple and durable setup for the occasional heavy pull. The shackle style suits rigging points where a closed connection is the better fit. The drop-side opening design accepts wire rope without threading an end through, which helps when a line is already rigged, and pressure lube fittings keep routine maintenance straightforward. Crosby also builds a bolt-retaining spring into 3" through 18" 419 blocks to help prevent lost bolts.
What Sets the 419 Series Apart
-
Forged steel shackle: A closed shackle connection for rigging points where a shackle is the preferred choice over a hook.
-
Drop-side opening design: Accepts wire rope without feeding a rope end through the block.
-
Bronze bushing sheave: A low-maintenance bearing choice for intermittent, heavy-duty pulls.
-
Nine sheave sizes: 3" through 18", so you can match the block to your wire rope and your load.
-
Crosby® documentation: Crosby states these blocks meet or exceed ASME B30.26 requirements, and 4-1/2" and larger blocks are RFID equipped.

Common Applications
-
Utility and line work: changing the direction of a wire rope pull, including gin pole setups.
-
Construction and field operations: redirecting winch and pulling lines around obstacles or to a better anchor point.
-
General rigging: directional load control where a wire rope needs to change direction.
-
Heavy rigging: the 16" and 18" blocks carry 15-ton ratings for larger-diameter wire rope.
How to Choose the Right 419 Snatch Block
Start with the wire rope. Each block is built for a specific rope diameter range, so match your rope to the range listed for the block. If your rope falls where two sizes overlap, such as 3/8" or 3/4", the larger sheave is generally gentler on the rope.
Next, look at the load the block will actually see. When a line changes direction through a snatch block, the load on the block can be higher than the pull on the line, and at a full 180-degree turn it can approach double. Choose a block whose working load limit covers that load with room to spare, and check Crosby's documentation or a qualified person for your setup.
Then consider handling. A 3" or 4-1/2" block is easy to carry up a pole or onto a rig, while the 16" and 18" sizes weigh well over 100 lbs. Our product experts can help you match a size to your rope, your load, and your crew.
Shackle, Hook, or Tailboard?
The 419 is the shackle style. If you prefer a hook, see our 418 snatch blocks with hook and bronze bushings. For a tailboard block, browse the 404 snatch blocks with bronze bushings.
Bronze Bushing or Roller Bearings?
Bronze bushings are a good fit for intermittent use where simplicity and durability matter. Roller bearing blocks reduce friction and are the usual choice when a block sees more frequent or more demanding use. If your work leans that way, compare the 419 snatch blocks with roller bearings.

Frequently Asked Questions
What does a 419 snatch block do?
It redirects a wire rope line so a pull can run from a better angle or around an obstacle. The 419 is the shackle-style block, with a drop-side opening design that accepts wire rope without threading an end through.
What size wire rope do I need for each 419 block?
The 3" block fits 5/16" to 3/8" wire rope, the 4-1/2" block fits 3/8" to 1/2", the 6", 8", and 10" blocks fit 5/8" to 3/4", the 12" and 14" blocks fit 3/4", the 16" block fits 7/8", and the 18" block fits 1" wire rope.
What is the working load limit of these blocks?
Ratings run from 2 tons on the 3" block and 4 tons on the 4-1/2" block to 8 tons on the 6" through 14" blocks and 15 tons on the 16" and 18" blocks. Confirm the rating on the block and in Crosby's documentation for your specific part.
What is the difference between the 404, 418, and 419?
They are the same family of Crosby® McKissick® snatch blocks with different connection styles: the 404 is a tailboard block, the 418 has a hook, and the 419 has a shackle. Pick the one that matches the rigging point you are working with.
Are these blocks rated for lifting people?
Follow the manufacturer's warnings and applicable regulations for every use. If you are unsure whether a block suits your application, check Crosby's documentation or a qualified person before use.
How do I know if I need bronze bushings or roller bearings?
Bronze bushings suit intermittent, heavy-duty pulls where durability and simplicity matter. Roller bearings are the usual choice for more frequent or more demanding use. Compare both in the 419 series using the links above.
