I used to be a salesman for a large industrial distributor. Over the years I have accumulated several different sizes of BRAND NEW, METRIC riveted roller link chain (in10ft boxes), as well as connecting and offset half links. I have METRIC chain in size 04B, 05B, 06B, 08B, and 10B (one 10ft box of each). The chain is pre-lubricated, in airtight plastic, in their original boxes, with a master connecting link included. I also have Individual METRIC connecting links and offset links in these sizes. Prices are well below anything on ebay or anyplace else I've found on the internet. All of these items can be shipped to you via the US Postal Service if you want to save some gas. Provide me with the PART#'s and the quantities you are looking for. I will promptly email you a price.
