Steel Base for Alto U-Grid Lighting Rigs

Overview

Introducing the ProX X-ALTOBASE, the heavy duty steel foundation built to anchor and stabilize the ProX Modular Rapid U-Grid lighting system on any stage, in any club, or on tour. Sold separately from the ProX ALTO7FTRIG pole and bar assembly, the ProX ALTOBASE gives production teams, lighting designers, and touring crews a dedicated, rock solid platform to stand their U-Grid fixtures upright without relying on a full truss system. If stability, portability, and fast load in and load out matter to your show, the ProX ALTOBASE is the piece that keeps everything grounded.

Base Dimensions

The ProX ALTOBASE measures 30" in length by 2" in width by 4" in height without casters installed, and rises to 7.5" in height once casters are added. This low profile footprint keeps the base out of sightlines while still providing a wide enough platform to hold the ALTO7FTRIG upright under load.

Weight Channel

Running through the interior of the base is a 1.5" wide weight channel, the space where ballast blocks are loaded to anchor the unit and keep it planted through the show. Each block weighs 5lbs, with four blocks fitting per side, giving crews a simple and repeatable way to dial in exactly how much ballast the rig needs for a given setup.

Casters

The ProX ALTOBASE rolls on 2" locking casters, making it easy for one person to reposition the base into place once assembled, without needing to lift or drag a fully loaded platform across the stage.

Compatibility

The ProX ALTOBASE is designed to pair with the ProX ALTO7FTRIG pole and mount bar assembly, sold separately, and is part of the larger ProX Modular Rapid U-Grid system used to build out scalable lighting walls and grid arrays for productions of any size.

Note

X-ALTOBASE is the Set of 2 - base designed for the  X-ALTO7FTRIG.  This listing is for the base only. No pole, mount bars, or rig included. 

Both the base & the rig can be purchased as a packge here X-ALTO7FT
