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 truss will carry 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.
Two sizes for 12" and 20.5" truss
