Serious Heavy Duty Truss has the same overall dimensions as Generic Heavy Duty Truss, but offers even greater load carrying capacities and spans than the original. The use of thicker chords and diagonals increases the bending and shear strength of the truss which is offered with Fork End connectors as standard.
