A chain having a plurality of inside links and guide links. The plurality of inside links each have a pair of apertures and are interleaved and connected to form rows. The plurality of guide links each have a pair of apertures and are placed outside of alternate rows of interleaved inside links to form guide rows. Connecting pins are received in the apertures and extend across the rows of the chain securing the links together. Spacing elements are found on opposite side of the chain, specifically between the guide links and the adjacent outermost inside links. The spacing elements act to maintain a spaced relationship between each of the guide link sand adjacent outermost inside links. At least one of the spacing elements on one side of the chain is a spring link holding the inside links in compressive frictional contact therebetween.
