McKissick 407 Super Champion Tail Board Snatch Block - 1-1/8 in - 20 Ton - 12 in - Bronze Bushing

Product Description

The McKissick Series 407 Super Champion Tail Board Snatch Block is a heavy-duty single-sheave block engineered for high-capacity rigging and pulling applications in oilfield, logging, construction, and heavy industrial environments. Rated to a 20-ton working load capacity and designed to accommodate wire rope up to 1-1/8 inch in diameter, the Series 407 Super Champion is built for sustained performance under demanding working loads. The tail board configuration features an extended mounting plate that allows the block to be secured to a fixed structure, vehicle, or anchor point, providing a stable attachment method suited to pulling and rigging operations where a conventional hook or shackle attachment is not practical or preferred.

The 12-inch sheave outside diameter provides a generous rope bend radius, helping to reduce wire rope fatigue and extend rope service life under repeated heavy-load cycles. This variant is fitted with a bronze bushing bearing, a bearing type proven in heavy industrial block applications for its high load-bearing capacity, durability, and resistance to contamination and harsh field conditions. The snatch block design incorporates a side-opening cheek plate, allowing the block to be attached to or removed from a wire rope at any point along its length without threading the line — an important operational advantage in field rigging setups where efficiency and accessibility are priorities.

McKissick's Super Champion designation reflects a reinforced, high-capacity construction standard within their block product line, purpose-built for demanding applications where standard blocks would be insufficient. The Series 407 tail board snatch block is commonly used in oilfield, logging, and heavy pulling operations where a secure, flat-mounted attachment point is required alongside the flexibility of a snatch block rope entry. All attachment hardware and anchor points used in conjunction with this block should be rated to match or exceed the 20-ton working load limit to ensure a safe and compliant rigging assembly.
