ProX XT-BTBP36ST-S40 Steel BoltX Base Plate Raised Frame for 12" and 16" Bolted Box Truss, F34 Truss and 1.5" Schedule 40 Poles

The ProX XT-BTBP36ST-S40 36" Steel BoltX Base Plate is a heavy-duty raised frame base designed to provide a stable and dependable footprint for 12" and 16" bolted box truss towers. Built entirely from steel, it is engineered for demanding touring, rental, event, and permanent installation environments. Its 36" footprint helps improve stability and load distribution, while the raised frame design adds structural reinforcement and helps resist twisting under load.

The base plate features dual mounting holes for 1.5" Schedule 40 poles, allowing centered or offset pole placement to suit different build layouts. It is compatible with ProX BoltX 12" and 16" bolted box truss systems and is drilled for F34 truss patterns. A universal 5/8" bolt pattern provides compatibility with many professional 12"–16" box truss systems. Four reinforced corner gussets add stability and anchoring points, while M16 threaded holes allow optional wheels or leveling feet to be attached directly to the plate.

Designed for professional production environments, the XT-BTBP36ST-S40 includes integrated hand holes for easier lifting and positioning during load-in and load-out. The plate is welded to TÜV standards by GSI SLV-certified welders and is load tested and inspected before leaving the factory. Built on ProX’s decades of live performance industry experience, this base plate delivers the strength, flexibility, and reliability needed for demanding stage and event applications.
