Challenge 100H Reinforced coil chains (GL20A-1(100H)/L%CHA)
Description
One roll of 20A ANSI100H marked roller chain unit contains 5 meters in length. (Certain products can be 50m or 100 meters, this is marked separately.) Each 5-meter unit package (box) contains a roll of roller chain and a piece of straight patent eye. The pins and connecting plates of reinforced chains are stronger than those of normal chains! The H marking refers to the Heavy Duty marking. 20A ANSI100H roller chains can be single-row (simplex, designation 20AH-1), double-row (duplex, designation 20AH-2) and three-row (triplex, designation 20AH-3). The pitch of the 20AH chains is 31.75 mm, the inner width is 18.9 mm, and the roller diameter is 19.05 mm. For roller chains marked 20AH, a cotter pin marked 20A and a sprocket marked 20A must be used.
