Application: "J Lock Chasers can be towed along the mooring catenary and will lock when the directional pull of the winch is reversed".Made from quenched and tempered steel, J Lock Chasers are used to recover embedded anchors, especially deep-penetration twin shank anchors.The unique design allows the chaser to be towed along the chain in one direction and then locks onto the chain when the pulling direction of the winch is reversed. As the chaser has now locked, the chain can be pulled and any tension in the mooring line is directly transferred to the chaser itself.It is therefore a safer option to use a J Lock Chaser as there is no slippage.The J shape allows for the catching of the anchor chain after the anchor has been installed. Due to the chasers excellent design and performance, it enables for the catching of the chain when the chaser approaches a mooring at the point where the catenary angle is as high as 45 degrees.
