Grapple

[soundman]

A product made by TMB that allows truss to be bolted perpendicular to another stick of truss in the middle of it to form a T. The advantage of using a Grapple over using corner blocks is that with a Grapple you are not limited to just the ends of the truss, you can put a connection along the length.

Grapples should be ordered in pairs as it takes two to make a connection.

The Grapple

From the website above:

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.​

Available for 12", 18", 20.5", 30", and PRT truss.​

WARNING!
Grapples must be installed by qualified rigging personnel only. Incorrect use of Grapples may cause hazardous conditions and possible injury. Only use Grapples for applications and loadings described in TMB's Grapple Application Guide. A qualified engineer must approve all other applications.​
