McKissick 417 Snatch Block - 3/4 to 7/8 in - 12 Ton - 8 in - Roller Bearing

Description du produit

The McKissick 417 Snatch Block is a heavy-duty snatch block engineered for crane, rigging, and wire rope deflection applications in industrial, construction, oilfield, and marine environments. Built to handle a 12 Ton working load, the 417 series delivers the strength and durability required for sustained heavy-load operations in demanding field conditions. The roller bearing sheave provides smooth, low-friction rope travel, reducing wear on both the wire rope and the sheave groove during high-cycle and heavy-load operations.

Featuring an 8 in sheave outside diameter and a maximum cable capacity of 3/4 to 7/8 in wire rope, this snatch block is sized for medium-to-heavy-duty single and multi-part line rigging configurations. The roller bearing design ensures consistent sheave rotation under load, which is critical for maintaining wire rope integrity and minimizing heat buildup during high-cycle operations. The snatch block configuration allows the wire rope to be inserted laterally without threading, enabling fast and efficient rigging changes in the field without disconnecting the rope end.

The McKissick 417 series is a well-established snatch block line used across construction crane rigging, oilfield operations, marine deck rigging, and heavy industrial lifting where a reliable, high-capacity wire rope deflection point is required. The 12 Ton working load rating and 8 in sheave diameter make this block well suited for a broad range of medium-to-heavy rigging applications. Proper rope-to-sheave diameter ratio should always be observed to maximize both rope and sheave service life.
