Unhappy

I have a Stanley opener and the chain sags quite a bit lower than the guide rail. The chain actually rubs against the door as it comes back. There doesn't seem to be any type of tightening device on the chain/cable nor at the sprocket. Do I need to cut the cable and add in a tension device of some kind? Thanks for the advice.

There is a tightening device. However, it is not easy to see. It is a rod with nuts on each end. It may be inside of your channel, but it is near your sprocket. Follow your chain slowly. I am sure your chain is not continous. Where the two chain ends come together, is the tightener. Tightening chains is fairly common. I think without looking it up is 1/2" dip in your chain. If your chain is too long, you may find you have to take out a link.
