9/22/2023 0 Comments Best snatch blocksJust always be aware of their safe working loads, as specified by the manufacturer.Īmong their other less endearing features is that both the block and the shackle can be difficult or impossible to open when under a load. If you want a snatch block to do a heavyweight job, use a big one. Snatch blocks are not made as strongly as regular blocks. There’s no need to chase down and reeve the bitter end. Even a line under some load can be forced into the swallow. The great appeal of the snatch block is, of course, that it can be put in place, opened to place a bight of line in what is called the “swallow” (the space through which the line runs) and closed. It doesn’t like loads improperly applied and if abused can fail suddenly and dangerously. The shackle trunnion, combined with a swivel post, becomes a universal joint, precluding the snatch block from getting caught with its knickers in a twist. (A real trunnion is the pins on either side of an old-fashioned cannon that permit it to tilt up and down.) It works even better with what somebody chose to call a “trunnion,” which means that the shackle pin itself is a hinge. The snap shackle works in concert with a swivel post to keep all leads fair. If the snap shackle used for attachment is a good one, the swinging arm will open easily and have a proper chamfer to actuate the spring-loaded pin and then permit it to lock home. And, of course, they can change line leads on anything. Snatch blocks also can serve in anchoring situations, sometimes positioned to prevent chafe. Attached to the boom bail or a saddle, they can hoist aboard a human or a dinghy.
