Installing a Fin for an Inflatable Board with a Threaded Fin Box

Step 1: Remove the plate from the fin hardware and keep it in your repair kit. It is not needed with a fin box that has threading.

Step 2: Insert the dowel in the large opening of the fin box and slide fin forward.

Step 3: Press the fin down in place. The hole will be lined up with the threading.

Step 4: Insert the thumb screw in the hole and screw into place until hand tight. Do not overtighten.

Step 5: When the Fin is removed store the Thumb Screw in the Repair Kit so it does not get lost.
