Key Features

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.


Strata Duraflex ST Highback - The Strata Highback is light and asymmetrical, with a firmer flex on the outside for support and a softer flex on the inside so you can tweak it harder and lean into your turns with more power.

Classic FLAD (Forward Lean Adjuster) - Zero out your highback lean for mellow cruising or park laps, or crank it up a notch for those high speed assaults when you need extra leverage and board control. Easy adjustment allows you to customize your highback lean on the fly.


Forma Lab Ankle Strap - New and improved, the Forma Lab Ankle strap utilizes a minimalistic design for a lightweight and surfy feel that is highly durable and features strategically placed padding for increased comfort.

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.


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 VI 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.

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.

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.


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.

Great Beginner to Intermediate park and freestyle binding
by SlashSquatch

Union Strata Snowboard Bindings
Great binding somewhere between intermediate and beginner as far as forgiving as a soft yet responsive binding. Very surfy loose feel depending on high back setting and comfortable reliable straps that endure a range of temps and still function properly. All that compound by the fact that Union in PNW with the baseplates guaranteed it’s no a brainer if you’re try to have support and send shit!!!

Good bindings but...

Really nice all around bindings, not so great touch on the details. Mind the sharp connecting pieces, especially the back of the heel angle adj. mechanism. I have a hole on the top layer, at the back of my brand new boots, thanks to all uncovered metal parts.

Could it work on a 4:4?

The Strata bindings come with a Union Mini Disc which is only compatible with channel and 4x2 mounting.
