Aluminum Tomcat Truss Grapple Bar for Truss Work Installation

5 0 Reviews

The Grapple allows you to make inline 90-degree connections between similar trusses anywhere along a perpendicular primary truss. The load capacity of the inline, secondary truss will be 75 percent of the manufacturer’s load rating. The primary truss must have point load calculations
taken into consideration. The secondary trusses must be supported at both ends. Cantilevering of truss is not recommended.

How It Works
Step 1:
Determine general location along the primary truss.
Step 2:
Install both halves of each GRAPPLE set onto the primary truss.
Step 3:
Align GRAPPLE bolts with the end-plate holes of the secondary truss
Step 4:
Apply included washers and hex nuts onto the GRAPPLE bolts. Make any position adjustments before final nut tightening.
The Aluminum Tomcat-Style Truss Grapple Bar is a specialized concert & event stage solution engineered for the secure, overhead installation and structural reinforcement of truss systems. This technically accurate rigging tool is manufactured from structural-grade 6061-T6 aluminum, utilizing a professional Connection & Material System that allows for the creation of intermediate suspension points between truss chords. Designed for high-stress production environments where precise load distribution is required, it provides a professional and stable environment for industrial-grade stage productions.

FAQ

What is the primary advantage of using a grapple bar over a standard sling?

Agrapple barprovides a rigid, fixed-point suspension that prevents "choking" the truss chords, distributing the load more effectively across thetruss architecture.

Is this compatible with all box truss sizes?

It is precision-engineered forspecific truss widthscommonly found in Tomcat-style systems. Always verify the center-to-center distance of your chords before installation.

Can it be used for horizontal bracing?

While primarily designed forvertical suspension and rigging, its structural integrity makes it suitable for variousmodular truss applicationsfollowing a professional load assessment.
