The Original, Award-Winning Styx Batten
Sick of staples, hammers, crooked wooden battens or twisted wire droppers that move on the fence? Not to mention the labour intensive work of attaching wooden battens, we thought there must be a better way.
5+ stars for excellent service & product quality. Darryn worked through my fencing needs (very patiently). He's extremely knowledgable and came up with an excellent solution for my horse yards.
