Baseplate:
Stage III Duraflex ST Baseplate: Duraflex blended nylon is specifically designed for cold temperatures -- offering unsurpassed levels of strength and longevity. A new era for nylon plastic components.
4 Point Multi-Density Thermoformed EVA Bushing: All four corners of the baseplate are void of pressure points and promote true board flex.
Universal Disks: Compatible with 4x4, 4x2 and Channel systems.
Highback:
Atlas Asymmetric Highback: Union's extremely comfortable, responsive and lightweight Atlas Highback is symmetrically designed with a tapered top section. The result is improved mobility and flex where you want it with support and durability where you need it.
Straps:
SonicFuse Straps: Features a multi-layer composite strap core that is fused together to form a single, articulated strap. This minimization of stitching increases the straps durability and reduces weight. Additionally, it evenly distributes pressure across your boot improving comfort and lateral mobility.
UltraGrip Toe Straps: Multi-Positional options and thermoplastic anti-slip material keeps you locked in and on point -- a simplistic, yet highly durable design.
Buckles:
Injected Magnesium Buckles: This high-tech process produces a material four-times the strength of aluminum with only half the weight. Plus, magnesium is easily recycled and remains the eighth most abundant material on the planet.
Additional Features:
Extruded 3D Aluminum Heelcup: Made of extremely durable extruded aluminium, designed to minimize toe drag while optimizing heel hold.
Canted Gas Pedals: Ideal for riders using a wide stance, Canted Gas Pedals supply extra leverage for ollie power. Canting also allows the ankle and knee joints to be aligned, alleviating pain.
Grade 8.8 Hardware: The most commonly used hardware is made from "mild steel" that has a property class of only 4.6. Considering how much stress a binding is under, Union uses only the strongest steel on ALL hardware.
Tool-Free Adjustments: No screwdrivers needed - Flip the levers for a quick and easy on-hill adjustment.
Union offers a lifetime warranty on baseplates and heelcups. If you break, or even crack your baseplate or heelcup during riding, they'll replace it for life. Guaranteed. All other parts are covered for 1 year from date of purchase.
