TRAVELLING WINDBAR ASSEMBLY – WINDBAR TUBE IN-
STALLATION
STEP 3 - FOR 4” OR 4-1/2” DIAMETER WINDBARS
Determine dimensions “C” and “D” from the chart and mark the lintel (jamb mount) or the
spreader bar (guide mount) at these dimensions from the outside of the end plates.
If installing a jamb-mounted windbar, weld a lintel bracket at each mark on the lintel, 6” from the
curtain. If installing a guide-mounted windbar, temporarily center and clamp a “windbar strap
clamp” at the specified location on the lower front spreader bar to match drill the 5/16” diameter
holes.
TRAVELLING WINDBAR ASSEMBLY
STEP 3 (FOR 6-5/8” OR 8-5/8” DIAMETER WINDBARS)
Determine dimensions “C” and “D” from the chart and mark the lintel (jamb-mount) or the truss
(guide-mount) at these dimensions from the outside of the end plates.
If installing a jamb-mounted windbar, weld a ratchet buckle at each mark on the lintel, 9” from
the curtain (see Detail B).
If installing a guide-mounted windbar, weld a ratchet buckle at each mark on the bottom of the
truss (see Detail A).
