The chain type pile guide is good to use when you need a little extra movement between your dock and your piling. The chain allows a little more horizontal movement compared to our other pile guides. Also, the chain is mounted to the pile guide with a clevis, which makes for easy removal.
We have two different versions of our Chain Pile Guide, Heavy and Light. They are almost the same except for the chain and clevis. The Heavy type uses 3/8" chain and clevis, light uses 1/4" chain and clevis.
