Minimal Base Contact = True Board Flex - Union baseplates are designed to provide supreme strength while minimally interfering with your board's natural flex. Minimal board to binding contact means sweeter response, better board control, and improved durability.
Duraflex Highback - Union exclusive Duraflex material was specifically engineered to maintain consistent flex in a wide range of cold temperatures.
Tool-Less FLAD (Forward Lean Adjuster) - Easy adjustment allows you to customize your highback lean on the fly.
Exoframe Ankle Straps - Independent suspension and support create a seamless interface. This super cushioned and lightweight design comfortably holds you in, but won't hold you back.
Hexgrip Toe Straps with Secure-Lock - These highly advanced toe straps are made from a thermoplastic anti-slip material to keep you locked in and on point.
Aluminum Buckles - Lightweight, fast in, and fast out. Union aluminum is second to none.
Size-Proportionate Fiberglass Index - Bigger riders require stiffer bindings. Union proportionally increases the fiberglass content in each size of their bindings so that any rider who straps in will have perfect support.
Stage V Duraflex Baseplate - This freestyle oriented baseplate comes canted with Duraflex injection. Ideal for those looking for more response at a price that won't break the bank.
3-Position Heelcup Adjustment - Minimize any toe or heel drag by dialing in your heelcups. Simply loosen heelcup screws and slide into correct position.
Extruded 3D Aluminum Heelcups - A new process removes as much excess material as possible in the heelcup to reduce weight while maintaining tried and true strength. Union heelcups undergo an anodizing process reinforcing the already bombproof apparatus with another 30-percent strength. It's serious strength in a streamline package.
Canted Gas Pedals - Ideal for riders who want a wide stance and extra leverage for ollie power. Canting also allows the ankle and knee joints to be aligned, alleviating pain.
Camber Disk - Compatible with 4x4, 4x2, and Channel mounting inserts, Union disks are bombproof and use the highest grade materials to insure the strongest connection between you and your board.
Multi-Density Thermoformed EVA Bushings - Union's innovative injected-EVA baseplate bushing system dampens vibrations underfoot to promote a more comfortable ride and a smooth, even board flex with no dead spots. Each binding size comes with its own durometer for custom performance.
Grade 8.8 Hardware - The strongest steel available on the market - the use of Grade 8.8 represents Union's commitment of delivering the strongest and most reliable bindings on the market today. Top to bottom.
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 put under, Union uses only the strongest steel (featuring a property class of 8.8) on all hardware.
Lifetime Warranty on Baseplate and Heel Cup - Covered under manufacturer lifetime guarantee against breakage of the baseplate or heelcup along with defects in materials or workmanship. This lifetime warranty DOES NOT cover broken bindings due to abuse or neglect, damage caused by any modification done outside the manufacturer's facility, or lost parts due to lack of hardware maintenance.
Highbacks, straps, ratchets and other components are covered under Union's 1 Year Warranty.
100% Ownership, 100% Focus - Union is 100% devoted to making the best bindings on the planet. From discovering new materials to CNC machining a new baseplate, everything is done in-house with zero outsourcing. Every single piece of a Union binding is completely exclusive to Union.
