Premier 2000 snare internal Cam spring

Premier 2000 snare internal Cam spring. This metal 'spring' fits inside the black plastic box, which sits inside the Premier 2000 snare drum shell. The springs enable the parallel snare mechanism to hold 'on' and 'off' positions of the snare mechanism. If your snare mechanism is slipping or not throwing on and off fully, these springs are probably broken. Although drums are fitted with two internal springs at each end, some drums only have one in each end. Used condition. International shipping,
