Chain Guide

The photos below show the design differences between some of the standard chain types that we offer.
Each chain type is available in a wide range of widths. Shown here are four widths of each type: large, medium, small & fine. You can click on any of the pictures below to see a more detailed illustration showing the relative sizes of the different chain widths. We have many more chains than are shown here, this is just to act as a guide.
Please note that these illustrations are intended to show the chain designs and the relative chain widths. The illustrations are not intended to show the actual chain widths - as the size of the illustrations will vary depending on the settings on your computer. The table below gives a guide to the actual width by chain type.
