Trigon Sports 13 Row 21' Supreme Series Bleacher

These 13-row Supreme Series bleachers from Trigon Sports are designed to provide durable, code-conscious spectator seating for schools, sports complexes, athletic venues, and recreational facilities hosting larger crowds. Constructed with an all-aluminum frame, the bleachers are engineered for long-term performance while minimizing maintenance requirements in outdoor and high-traffic environments. An 8-inch row rise combined with a 24-inch tread depth creates comfortable spacing and improved sightlines throughout the seating structure, while 10-inch aluminum seat planks and a 17-inch front-row seat height support convenient spectator access and visibility.

Double footboards and risers are included on every row to provide consistent underfoot stability and structural support as seating elevation increases. Integrated aisles with handrails help guide spectators safely through the seating area, while chain-link guardrails add additional perimeter protection for improved crowd safety during busy events. Available in 21-foot lengths, these Supreme Series bleachers are built to accommodate higher-capacity seating needs while delivering reliable long-term durability and organized spectator access for demanding athletic and recreational environments.
