I am selling ANSI standard size number 60 roller chain by Diamond Chain Company made in the USA. You can see the specs at diamondchain.com. Diamond brand is probably the best roller chain made. I am selling it by the foot, cut off of 50 foot rolls. Sometimes this means a chain will have an extra connector in the chain if I am finishing up a roll. I will cut to the exact length you need if you message me with the needed length. The price will be to the next longer foot if it is more than one inch. The best way is to count the number of pitches. The pitch is the length from pin to pin. This will always be an odd number. Adding the connector makes it an even number. The pitch of 60 and 60H  –  3/4 inch. You must purchase the next longer foot. You will need to purchase the chain, then return to the listing and purchase connector links as needed, then return and purchase offset links as needed. Wait for me to send an invoice and I will combine the purchases and ship one package and one shipping charge.
