Aluminum jacket to repair or support an 8" piling for dock or boat lift. Has two holes drilled in to it, but still works fine. Worked well for over 8 months until new pile installed. Length is 47" and 1/8" thick aluminum. If ad is up, it’s available. Will not respond to "Is this still available". Can meet with buyer at Lemon Bay Shopping Plaza: intersection of Englewood Rd (776) and Englewood Isles Pkwy in front of Libee's Bar Grill.
