Modii Universal Fin Box Depth Checker Tool (Left and Right set )


Ever wanted a finbox that will fit a lot of different fins and systems?

Modii has developed a box that will fit almost every thing!!

The fin box has been developed to be one of the lightest, strongest and most versatile!

The Finbox comes in 8 degree for your High performance boards  , 4 degree for your Fish and retros and centre box to make your Thrusters and 5 fin set ups complete.


This tool is to help make a perfect install - The screws on the side file away the foam in the right place so your box fits perfectly every time  it comes in a pair so you have the right tools to do all sides and centre boxes  


How to install using the depth checker : Option 1: buy the dedicated install kit 

Option 2: Buy the "Futures one pass adapter"  use all the tool from your "One Pass install kit"

Step1: Measure up as using the futures kit - mark fins out as per using futures.

Step 2: Use the futures  target to line up your cuts, drop in the adapter at the back of the Jig to reduce the size of the cut (good it idea to tape it in so it doesn't move)

Step 3:  Use the 3/4 one pass router bit  to cut all boxes in 

Step 4: Once holes are cut,  use the Depth Checker to make sure all holes are correct and right depth - this will file away the foam in the right areas to make the fit perfect. 

Step 5:  Using dummy fin glue in your boxes at the right angle (milled fibre resin mix preferred) 

step 6: Glass in as you would for a futures box 

step 7: Sand the ridge off to break through the glass as you would do with a futures box

step 8: once board is finished screw in the grubscrews (1 for FCS2 fins 2 screws for all other systems per box) and go ride!
