The I1 Intermediate Truss is designed to be slid over a T1 Truss. As the bottom chord of the truss is not continuous it has no spanning capacity of its own.
The truss matches the span of trusses of C1 and C2 columns
When using with the glazed roof sections, the truss fits tightly between the frames of the rooflight molding. The truss plate rivets may need to be sanded or filed off in this location to allow the truss to fit neatly into the rebate.
This truss is compatible with:
C1 Columns
C2 Columns
R1 Roofs
T1 Trusses
Valance Type 2
Valance Type 4
