290 Series Platforms provide stable, fixed-height mounting for large components and assemblies. The platforms are comprised of thick anodized aluminum plates and rigid steel posts with a durable, satin-chrome finish. The top plate has an array of tapped and clearance mounting holes for attaching components; the bottom plate has two rows of clearance holes for tie-down to tables or magnetic bases. Four steel posts connect the plates. All components are available in sets or separately.
