for recommended dimensions
and header weldment location). Using beam clamps
(depending on design) and hardware provided, attach
header weldment to column weldment.
3.2
Tighten hardware. Refer to
chart 3A
for proper
torque.
3.3
Install remaining header weldments (repeat Steps

10” tall, wide flange headers with 5/8” hardware require a shim (supplied) to
obtain the correct beam clamp tail length to match the header flange thickness.
