Abstract
A chain link is attachable to forward and rearward links of identical construction to form a chain. The chain link includes a left and a right sidewall that each include a rearward and a forward plate with the forward plate inwardly offset from the rearward plate. Each rearward plate has a slotted aperture. A connecting pin having a rim at each end is inserted into a first portion of the slotted aperture which is sufficiently large for the rim to pass therethrough. The connecting pin has a connecting shoulder that extends inwardly from each rim and which engages a second portion of the slotted aperture in a snap fit engagement. The forward plates of each sidewall each have open ended slots for engaging a forward link. A rearward link engages a portion of the shoulder of the connecting pin. A roller is disposed between the two sidewalls freely rotating on the connecting pin.
