The Upper Mounting Bracket requires a single fastener (not supplied) to attach it to the substrate, or if mounting to steel, it can be welded. It can also be eliminated by attaching Suspension Rods directly to the steel substrate. Consult a structural engineer for recommendations.
When mounting substrate is over 6" (152 mm) from the top of the SPS Overhead Track, CRL Cat. No. 90TSA1 Angled Support Assemblies
must be used to stabilize the entire SPS Overhead Track.
