Black 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.
