Patented dual roller system. The box is obtained from a single sheet of metal using a system we invented to avoid welds and create 3 anchor points. The roller in contact with the shaft is floating, eliminating friction. The roller in contact with the trigger completely eliminates friction during the shot. The trigger does not harden during the release. Smooth shaft release. Primarily constructed from AISI 316 stainless steel. Manufactured using 3D metal injection molding technology. The trigger is made from our specially formulated super-resistant alloy with a hardness of 55HRC. The shaft insertion roller is made from 17-4ph and is wear-resistant. The line release is rounded; it neither consumes nor damages the line. The opening angle of the line release is 65 degrees. Tested with a load of 550 kg. Weight: 76 grams. Same dimensions and features as the Back model. The box is folded with a system that avoids welding in the wings for screw fixation, with the addition of a third screw in the back of the box. 00.0003.00 Silver 00.0003.02 Gold
