      • Why is this not in the store.

      The parts work fine and are needed for 8' and larger doors. Why is this not available in the store? The added delay of shipping was an issue for me. The drive chain is compleatly replaced. They have you using master links in two places why not keep the cost down by adding only the required length of chain .
