Product Description
20″ x 20″ Steel Base Plate | Heavy Duty Truss Stabilizer – Black (EVT12S-BP20S)
The EVT12S-BP20S Steel Stabilizing Base Plate is a heavy-duty, 20-inch square foundation designed to provide rock-solid stability for vertical truss towers. Weighing in at 51 lbs (23 kg), this plate adds significant ballast to the bottom of your structure, lowering the center of gravity and ensuring safety for lighting totems, trade show arches, and stage supports.
Function & Compatibility:
Constructed from high-strength Q235 Steel, this base plate features a universal slot design compatible with EVT12S (12″ Plated), EVT20S, and EVT290S (290mm) truss systems. It is finished in a professional Matte Black Powder Coat, making it non-reflective and ideal for broadcast environments. It includes an integrated carrying handle and dual 1.5″ Schedule 40 pipe flanges (one center, one offset) for adding pipe uprights or banner poles.
Key Features
- Heavy Ballast Weight: At 51 lbs, this steel plate provides essential counterweight for vertical stability.
- Universal Slot Design: Elongated mounting slots (18mm wide) accommodate various bolt patterns for different truss brands and sizes.
- Matte Black Finish: Anti-reflective powder coat prevents glare in photography and studio settings.
- Integrated Flanges: Includes two flanges for 1.5″ Schedule 40 pipe (approx 1.9″ OD), allowing for pipe-and-base applications.
- Durability: Q235 Steel construction withstands heavy traffic and rough handling.
- Convenience: Laser-cut handle allows for easier positioning and transport.
Designed by Evolve Truss (Distributed by Truss Genius), this plate is the professional standard for stabilizing ground-supported structures.
⚠️ Safety & Engineering Notice
❗ Critical Stability Information:
- Usage: Base plates increase stability but do not replace the need for ballast (sandbags) on tall structures or in outdoor wind conditions.
- Load Handling: Never suspend loads from the truss connection points on the base plate.
- Inspection: Check that the steel is flat and not bent before use to ensure a level truss tower.
Important Guidelines for Safe Use:
- Ensure all bolts (for plated truss) or half-couplers (for conical truss) are fully tightened using the provided slots.
- Handle with care; at 51 lbs, this plate can cause injury if dropped.
- Installations should be completed by trained professionals.
- A licensed structural engineer must review any load-bearing setup.
⚠️ Compatibility Warning
Crucial Steps for Safe Assembly:
- Hardware Check: This plate connects via Bolts.
- For Plated Truss (EVT12S): Use standard Grade 8 bolts through the slots.
- For Conical Truss (EVT290S): You will likely need Half-Couplers (Spigots with stud) to bolt into the plate slots to accept the truss. Verify you have the correct connection hardware.
- Pipe Sizing: The flanges accept 1.5″ Schedule 40 Pipe (1.90″ Outer Diameter). Ensure your upright pipes match this specific diameter.
