Heavy duty riveter for .404" and ¾" Harvester chains. Extremely robust workmanship enables heavy saw chains to be riveted efficiently. The long lever arm presses the rivets against the rivet head with tremendous power, so that an excellent result can be achieved with little effort. All GB riveters fit on the same base plate (13-091-03) and can be easily mounted or replaced. The base plate 13-092-03 is not included in the scope of delivery. Weight 3.8 kg.
