The Mini Breakaway Pulley from Detonation Technology allows an EOD Tech to create a change in direction during a remote pull. A breakaway pulley can reduce the number of approaches that have to be made when remotely moving an improvised explosive device. The Mini Breakaway Pulley is small, measuring 3″x1″x.5″; light weight, at 2.5oz; and durable, being made entirely from Stainless Steel and Delrin. The breakaway action is triggered by a knot in the line, no additional parts needed. The pulley is built to use line between 5/64″ and 1/8″ (2-3 mm).
