Jerry Stage Truss specializes in high-quality, general-purpose aluminum lighting and stage trussing designed for live stages, theaters, nightclubs, church installations, mobile applications, trade shows and retail applications. These Jerry Stage products are built using 6082-T6 Aluminum Alloy compositions. This lightweight, corrosion-resistant aluminum has a very high tensile strength, giving you the support and stability you need. The Jerry Stage Truss Conical Coupling System allows for genderless trusses, providing a more precise line up of chords and fastening points, while the conical shape of the couplers helps maintain overall rigidity at the stress points and makes parts harder to damage. This system also makes assembly quick and easy with very few tools needed to complete set up.
