Our large post fitting pliers are a specialized tool for reducing the center hole of a woodwind post to remove play between the post and rod that travels through it. When the hole in a post is too large for the rod that travels through it, even properly fitted keys are noisy and difficult to adjust. Precision adjustments are nearly impossible. Until we designed these pliers, fixing these posts was very difficult. Technicians would need to float solder into the post head, sleeve the post head, oversize the rod or, in the case where it is the last post on a stack, split the end of the screw slot. These procedures are very time consuming or unsightly. Fitting posts with these pliers takes seconds and the resulting job is invisible and long lasting.
