1. The 800mm Truss Compatibility Lie (The Geometric Impossibility)
The Problem: The sheet states that a 1000 × 1000 mm base plate is compatible with 800 × 800 mm trusses.
The Structural Reality: An 800mm square truss leaves only 100mm of clearance on each side when placed on a 1000mm base plate frac{1000 - 800}{2} = 100\text{ mm}. While it mathematically "fits" inside the outer square boundaries, it is completely unviable for actual safe rigging. An 800 × 800 mm truss represents a massive, heavy-duty structural tower meant to support heavy roofs or line arrays. Bolting it down requires its heavy steel couplers or half-conicals to sit directly over deep reinforcement gussets, leaving no room for the adjustable leveling legs or anchoring points on a tight 1000mm plate. Furthermore, an 800mm truss on a 1000mm base provides virtually zero geometric leverage against tipping forces, turning a tall tower into a severe safety hazard.
The Fix: Remove the 800 × 800 mm compatibility claim. A 1000mm base is engineered strictly for standard 290 × 290 mm (Spigot/M290) and 400 × 400 mm (M400) trussing systems.
2. Ambiguity in "Reinforced Steel Frame" Weight Dynamics
The Problem: The text notes a Weight: 38 kg (~84 lbs) but describes the entire unit simply as a "reinforced steel frame."
The Rigging Reality: In staging production, ballast and ground-support plates come in two styles: hollow steel matrix frames or solid, heavy-gauge steel perimeter plates. For a 1000 × 1000 mm steel plate to weigh exactly 38 kg, it is a hollow, perimeter-reinforced tubular steel frame profile with integrated cross-braces, not a solid slab of steel (which would weigh over 60 kg).
The Fix: Clarify the physical architecture of the base so structural engineers can calculate true self-weight and ballast requirements.

Core Structural & Safety Architecture
Multi-Format Bolt-Circle Matrix: Precision machined to accept half-conical receivers for both 290mm and 400mm square aluminum truss lines, serving as a universal foundation asset for rental inventories.
Articulated Swivel Leveling: Outfitted with 4 heavy-gauge steel adjustable feet that compensate for uneven outdoor terrain or sloped arena floors, transferring vertical down-loads safely to the ground.
Low-Profile Load Distribution: The hollow tubular steel matrix distributes high static down-loads over a wide $1\text{m}^2$ boundary area, preventing localized floor punching or soil compression when rigging vertical pillars.
High-Structure Wind & Ballast Mandate
⚠️ RIGGING SAFETY DIRECTIVE: A truss base plate serves primarily as a geometric anchor and alignment point for a vertical column—it does not replace the need for active stabilization. When assembling vertical totems or goals over 3 meters in height, or when deploying outdoor structures exposed to wind vectors, additional perimeter sandbags, solid concrete ballast weights, or structural guy-wires must be mechanically secured to this base platform to prevent catastrophic tipping. Do not attempt to mount trusses larger than 400mm on this unit.
