High Technology Hook (HTH) Center Pad required to mount a set of Quattro double boots to the ski or an optional FMX/XFM plate.
For direct-to-ski mounting, the center pad is made from a 4" wide and ~14" long substrate of 3M adhesive and ABS laminate. The adhesive is strong and waterproof, but comes off clean without residue when it's time to remove. Apply and remove using some gentle heat.
The FMX/XFM option includes HTH hook 4" by 30" long, without the base, so the HTH can be applied to the plate.
The package also includes some extra loop for the boots as illustrated.
