The 30mm Snatch Block is a versatile pulley that can be easily attached to a line without having to thread it through. Its dynamic bearings, which consist of twin rows of stainless-steel ball bearings running on a stainless-steel rail, provide superior load-carrying ability and longevity compared to other systems with plastic rails. This snatch block does not have a keeper mechanism for its side cheek, but it can be opened under load by inserting a marlin spike or screwdriver. An essential tool for any rigging system that allows for quick and efficient line redirection or increased purchase.
