The Caprail / Topsill is engineered for ice rink dasher board systems where durability, safety, and a clean finished edge are essential. Manufactured from premium high-density polyethylene, it protects the upper perimeter of boards from repeated puck impact, stick contact, and general wear. Facilities can request specialty finishes such as Hair Cell or Orange Peel textures to better match existing board systems or provide enhanced surface grip. The moisture-resistant and low-maintenance material ensures long-term colour stability and structural integrity, making it suitable for both new installations and retrofit arena upgrades.
