The Master Pull SB55000-14 is a block like no other. It was designed to be both lightweight and small, yet extremely strong. Many conventional snatch blocks are heavy, large, and cumbersome. They take up unnecessary space in the vehicle and make rigging more difficult.
The SB55000-14 snatch block has a compact form, weighs only 5 lbs, yet has a breaking strength of 55,000 lbs! With a 2:1 safety factor this block offers a maximum load of 27,500 lbs.
Although this snatch block can be used with steel wire cable, it was specifically designed for use with synthetic winch lines. Shrink fitted nylon protector plates prevent synthetic rope from contacting any sharp, metal edges of the block and a stainless steel sheave provides a smooth contact surface for synthetic rope up to 9/16” (14 mm) diameter.
The stainless steel sheave rides on a maintenance free, Kevlar bearing, so no greasing is required with this block. For durability, the side plates are powder coated with a black hammered finish.

We replaced our 24 lb snatch block with this 5 lb snatch block. The snatch block has been used 4 times with steel rope and it has operated flawlessly.
We test materials in our facility. The snatch block was attached to the tip of a 50 ft fiberglass reinforced pultruded pole, 15 inches in diameter. The other end of the pole is restrained in a fixture imitating setting the pole in the ground 7 feet. It required between 13,000 and 15,000 lbs (measured with a load cell) to break the pole.
Since the snatch block only weighs 5 lbs., it is much more desirable to use than the 24 lb snatch block, because of handling and the dynamic properties of the fiberglass poles when they are taken to failure. Think paddles with the elastic/rubber string and the rubber ball attached. The fiberglass pole tends to slap the snatch block several times when taken to failure, just like when you paddle the rubber ball on the elastic/rubber string.
So far, with only 4 tests of the snatch block, it is very impressive. We will see how it holds up over time.

1. High strength rating.
2. Handles 1/2" rope I use (handles up to 7/8")
3. Self-lubricating (no greasing required)
4. Armored to protect rope from any edges
