Black Diamond Helio Demo Heel Adjustment Plate - 60mmBlack Diamond Helio Adjustment Plates are the perfect way to ensure maximum swapability between your skis, boots, and bindings. The plates are thin to keep a low profile against the ski and have four tension bolts for maximum hold. The Helio adjustment plate allows to easily move the heel piece of Black Diamond Helio bindings up to 60mm. This plate creates a bridge under the old holes to avoid the weakening of the ski.
