Antal's Maxi Snatch Blocks are available with a sheave diameter of 90mm or 120mm. The cheek plate revolves around the sheave axle allowing the block to open; a safety pin, which engages automatically on closing, stops the block from opening accidentally. The sheave is made from a high-strength resin and cheek plates formed from hard anodized aluminium alloy, held together with high-strength stainless steel (17-4-PH) structural pins.
These blocks can come supplied with a shackle or snap shackle, or as a stand-up block with 4-srew permeant pad-eye or screwed pad-eye.
