ProX F34 Stage Roofing Ground Support Truss System with F34 Center Cross and Chain Hoists — 21 x 21 x 23 Ft
XTP-GS212123-CF34 Overview
The ProX XTP-GS212123-CF34 is a professional aluminum ground support roofing system built around heavy-duty F34 box truss construction, delivering an interior working envelope of 21 ft wide × 21 ft deep × 23 ft high (6.3 m × 6.3 m × 7 m). The system is engineered to support lighting fixtures, line array speakers, LED video panels, and other production equipment across concerts, music festivals, touring productions, houses of worship, and corporate stage events. A reinforced F34 center cross beam is included to increase overall rigidity, improve load distribution across the roof grid, and provide additional rigging positions at center stage. This system is purpose-built for staging professionals, rental companies, and production crews who require a reliable, modular roof structure with efficient setup and breakdown.
The modular construction method uses standardized truss components, allowing crews to assemble a full roof structure quickly while maintaining structural integrity. Integrated chain hoists enable the roof grid to be safely raised to the desired height with even weight distribution across the system.
Key Features
- F34 Box Truss Construction — Heavy-duty aluminum F34 truss throughout the system provides professional-grade structural integrity for demanding live production environments.
- 21 x 21 x 23 Ft Interior Envelope — Delivers a working interior space of 21 ft wide × 21 ft deep × 23 ft high (6.3 m × 6.3 m × 7 m), suitable for mid-scale to large stage productions.
- Reinforced F34 Center Cross Beam — Increases roof grid rigidity, improves load distribution, and adds a central rigging position for moving heads, LED pars, and other production fixtures.
- Integrated Chain Hoists — Allow the roof grid to be safely lifted and positioned at the desired height while distributing weight evenly across the ground support towers.
- Sleeve Block Lifting Mechanism — Travels along the vertical tower truss segments and is secured mechanically to the tower head section once the target height is reached, maintaining stability under load.
- Weather Cover Compatibility — The center cross beam serves as a secure anchoring point for stage tarps or weather covers, simplifying tensioning across the roof structure for outdoor productions.
- Modular, Standardized Components — Designed for both temporary event production and semi-permanent installations, with a construction sequence that allows efficient assembly by production crews using standard truss hardware.
- Broad Application Range — Suited for touring productions, rental inventory, music festivals, houses of worship, and corporate stage events requiring a dependable, transportable roof structure.
