One-Piece, Folding Support Assembly: Save setup time by simply rolling the multi-level audience seating riser into position and unfolding it in place. Save storage space: an 18-level riser is 54' extended but only 5 1/2' stored. Rely on consistent operation because the few moving parts seldom incur maintenance. Eliminate time spent looking for parts or tools.
Modular Design: Configure riser seating to best suit each event. Drop off or add levels in front or back. Build to unlimited width overall.
Decks Bridge Between Support Assemblies: Save time with fewer supports to set up and tear down. Greatly reduce leveling time because fewer elements contact the floor and the open area allows easy access. Minimize your initial investment because fewer supports are required.
Locator Nodes: Save time as the decks self-align quickly and easily, fastening without tools, clamps or clips. Save time because, in a single step, placing the decks also aligns and connects the riser bays (sections).
Adjustable Screw Feet: Compensate for uneven floors with 3" of easy, fine-adjustment leveling. Save maintenance costs because tough, 3/4" Acme-thread screw resists damage (compared to typical "V" threads). Protect floor surfaces with sure-grip 21/4" diameter urethane pads.
Nylon Bearings: Unfold and fold the support assembly smoothly and quietly. Reduce maintenance by eliminating metal-on-metal wear.
Ball-bearing Casters: Reduce setup effort by rolling the support assembly to and from storage and during extension and closure. Move system assembled (if desired). Eliminate movement while in use: the casters retract after the system is positioned, allowing the screw feet to contact the floor and carry the load.
Performance: Certified live load capacity of 100 pounds per square foot. Certified sway load of 300 pounds per level.
