Hammer-Blow Conversion Kits are added to ductile iron chain wheels that are attached to problematic or sticky valves. The “hammer” action makes opening or closing sticky valves easier for an operator of any size without damaging the chainwheel or valve. This accessory can only be added to ductile iron chain wheels because of their shock resistant construction. Included in each kit is the Hammer-Blow mechanism and fasteners required to attach the mechanism to the spokes of the chainwheel.
