What sizes of truss can this base plate accommodate?

The EVT12S-BP20S features elongated 148mm bolt slots, allowing it to act as a universal base. It is compatible with 12x12 inch (EVT12S), 290mm (EVT290S), and even larger 20.5x20.5 inch (EVT20S) square truss profiles.

Why are there two pipe flanges on this plate?

This plate includes dual 1.5-inch Schedule 40 pipe flanges. The center flange is for standard symmetry, while the offset flange allows you to position uprights closer to a wall or drape line, maximizing floor space.

Does this plate have carrying handles?

Yes, it features a laser-cut carrying handle cutout for easy transport. At 51 lbs, it can typically be moved by a single person, though proper lifting techniques or gloves are recommended.

Product Description

20×20 Steel Base Plate & Heavy Duty Truss Stabilizer – Matte Black (EVT12S-BP20S)

The EVT12S-BP20S is a premium 20 in x 20 in (508 mm x 508 mm) steel bottom plate engineered specifically for professionals who require uncompromising structural stability. Weighing a solid 51 lbs (23.13 kg), this Q235 steel plate is a deliberate, professional-grade upgrade from standard lightweight aluminum plates. It is designed to act as an essential built-in ballast for high-traffic environments and complex staging structures, delivering the rock-solid foundation required for serious event production.

Engineered for Professional Production Environments

This heavy-duty structural hardware product is manufactured to meet the specific demands of specialized production crews and rigging teams:

Lighting Totem & Vertical Truss Builders: When building free-standing vertical columns in high-traffic environments, standard aluminum plates simply cannot provide enough stability. The 51 lb solid steel construction of the EVT12S-BP20S acts as a reliable ballast, keeping top-heavy totems grounded and secure.
Broadcast & Film Production Crews: Reflective surfaces are a critical issue on camera. This base plate is finished with an explicitly non-reflective Matte Black Powder Coat, ensuring your structural rigging blends seamlessly into the shadows and eliminates unwanted glare from intense studio and stage lighting.
Stage & Event Production Companies: Built for heavy-duty rigging teams sourcing structural floor bases for large-scale arches, load-bearing towers, and complex stage supports where lightweight plates are entirely insufficient.
Trade Show Exhibitors: Perfect for companies building 12-inch bolted truss arches or towering banner displays on the trade show floor, where absolute floor stability and compliant ballast weight are absolute requirements.

Maximum ROI for Rental Houses & AV Integrators

The EVT12S-BP20S is designed to be a high-value, multi-purpose asset for your equipment fleet:

Consolidated Rental Inventory: Engineered with a versatile multi-pattern slot design, this single plate bridges the gap between different connection types. It seamlessly accommodates standard 12″ and 20.5″ plated (bolted) truss, as well as industry-standard 290mm (F34) conical truss systems, making it the ultimate multi-system plate for mixed rental fleets.
Dual-Purpose AV Integration: Built with dual Schedule 40 pipe flanges (featuring both center and offset mounting points), this plate allows AV system integrators to instantly add banner poles, lighting pipes, or drape uprights directly to the heavy-duty base.

⚠️ Safety & Engineering Notice

❗ Critical Rigging Information:

Stability & Additional Weight: While the 51 lb weight acts as an excellent base ballast, the use of additional sandbags is still highly recommended for maximum security when building tall vertical totems or considering transverse forces like wind load outdoors.
Load Distribution: Ensure your vertical truss or Schedule 40 pipe is perfectly plumb and that the load is balanced evenly across the base plate.

Important Guidelines for Safe Use:

Thoroughly inspect the base plate and connecting hardware for damage or defects before use.
Ensure all coupler pins, bolts, and cotter pins are fully engaged and secured tightly to the base plate.
Assembly should only be carried out by personnel familiar with heavy-duty trussing techniques.
The purchase of this product does not authorize or approve a specific installation or use. A licensed professional engineer must review all structures, lighting plots, or other truss uses.
