Aluminum Ferrules for connecting, splicing, or repairing round tube and rod of the corresponding sizes. These aluminum ferrules are lightweight, strong, and the perfect  method of fitting two short rods or tubes together creating a longer pole.

Many uses include, but not limited to:

  • Tent Pole Ferrule
  • Repair a Tube or Rod
  • When assembled, the de-burred edges make it easy to sleeve into fabric
  • Repair a kite

1/4 inch Aluminum Ferrule works best with 1/4 inch Tube and 1/4 inch Rod

5/16 inch Aluminum Ferrule works best with 5/16 inch Rod

3/8 inch Aluminum Ferrule works best with 3/8 inch Tube and 3/8 inch Rod

1/2 inch Aluminum Ferrule works best with 1/2 inch Tube and 1/2 inch Rod


The best adhesive to use to attach the aluminum ferrules to then ends of the fiberglass tubes or rods (or any tube or rod that is smaller than the ID these will accept) is JB Weld, Original Cold-Weld Formula. Mix the epoxy then apply a generous layer around the end of the tubing or rod. Slide on the ferrule and allow time to set. During the adhesive setting time, be sure the ferrule is in-line with the tube or rod. If using on Max-Gain Systems fiberglass tube or rod, the tolerances are close where achieving this will be more simple.
