TS 4.0+ Toe Straps - Simple, lightweight, durable - The all-new TS 4.0+ toe strap keeps you locked in for the ride down without letting you know it’s there. A new shorter buckle base helps to reduce weight and pressure points. Easily adjust to any boot with the quick snap of the pin adjustment, no tools needed.

Magnesium S1 Ratchets - When you ride 100+ days a season your ratchets take a beating. Freezing temps, water damage and constant strapping and unstrapping all play a role in the longevity of a binding ratchet. Lucky for you, the all-new Magnesium 4.0 ratchets are Union’s answer to the elements. A fully integrated spring protected from the harsh outside provide you with Union’s best ratchet to date. Longer life span and better spring return guaranteed.

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.

S11 ASYM Duraflex ST Baseplate - Asymmetrical Baseplate for increased torsional board flex. All-new Astro Washer prevents heelcup slipping. Made with Duraflex ST Nylon.

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.

Universal 4x2 Channel Compatible Minidisk - Designed to create a minimal contact footprint for even board flex.

Compatible with any traditional 4-hole or 3-hole snowboard mounting inserts, along with Burton snowboards featuring The Channel. You can mount Union Bindings on any board you choose.

Not compatible with 4x4 or with boards featuring powder pack setback insets.

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.
