Union Highback to Ankle Strap Hardware Black

The Union Highback to Ankle Strap Hardware Black kit renews the hardware around the ankle strap connection on compatible Union bindings. It is useful when a screw or barrel has been lost, a thread is damaged or an older assembly repeatedly develops play. The kit contains the matching screws, inner and outer washers, and barrels needed for that connection. It gives you the small components for a repair without requiring a complete new strap or highback.

The hardware uses grade 8.8 steel, with a corrosion-resistant finish and Nylock screw-retention coating. These are working fasteners within a moving binding assembly. Correct placement of the washers and barrel matters because the connection needs to be secure while allowing the intended movement. Compare the assembled order on your existing binding before dismantling it. A quick photo of each side can make that comparison easier during reassembly.

The pack contains four ankle screws, four external washers, four internal washers and four barrels. Separate the parts into matching groups before starting. That helps you see whether the old hardware is complete and prevents an inside washer being confused with an outside one. The included mesh bag is useful for keeping the remaining components together. This kit concerns the binding assembly; it is separate from the hardware that fixes the mounting disk to the snowboard.

Union lists its strap bindings from 2016 onward as compatible with this replacement family. The kit is particularly relevant when restoring a previous-generation setup with loosening ankle hardware. Check the existing attachment layout on the actual binding, especially if it has already been repaired using mixed spare parts. A shared model name does not tell you which components a previous owner installed, so compare the connection rather than guessing from appearance.

When fitting, keep the washer orientation and barrel alignment consistent with the binding's instructions. Start the screw carefully and use the correct tool, avoiding force on a misaligned thread. Tighten and check the assembly as specified by Union. Afterwards, operate the strap through its normal movement and check for unwanted play. If the surrounding strap mount or baseplate is cracked or deformed, replacing the screws alone will not restore it. During routine care, remove grit, dry the binding and inspect the connection after travel or a hard impact.
