Abstract
A link for a conveyor chain includes a first portion and a second portion laterally spaced apart from the first portion. The first portion includes a first sprocket-engaging pin, and the second portion includes a second sprocket-engaging pin. The first sprocket-engaging pin and the second sprocket-engaging pin protrude laterally away from one another. The first sprocket-engaging pin and the second sprocket-engaging pin may each have an oblong cross-section. At least one retainer can secure a connecting pin against movement relative to at least one of the first portion and the second portion, and each retainer can be positioned substantially within one of the first portion and the second portion.
