Yes you CAN fold aluminium tubing.

Tried and trusted on hundreds of boats, our patented Gemini hinges are available in a variety of sizes to meet different needs. 

Use them to:

  • Make spreader bars on biminis that eliminate tensioning straps for a cleaner look and better cockpit access.
  • Install grab rails and pusher bars on dodgers that fold quickly for easy storage.
  • Make folding tables and T-tops, openings in life line rails and stowable jumper seats.

Made from acrylonitrile butadiene styrene (ABS) plastic, fiberglass reinforced, with a 316 stainless steel link.
