Continue assembling beams until all are completed flat on the ground, as above.
Install SpanLatch Purlins and Cross-Cabling
On all but the first end beam to be raised, bolt the fixed ends of SpanLatch purlins to the top
of the 2” cylindrical purlin spacer at each apex joint and each base column joint (#2, 4, 5, and
7 in drawing on Page 10). Snug-tighten the locking nut of each purlin bolt and gently swing
each purlin outward & downward until it rests with its stop nut against the beam (jaws open
downward). (To avoid damage, do not let purlins swing under their own momentum.) In cross-
cabled bays, attach the snap end of each color-coded cable to the appropriate purlin end and
let the turnbuckle end of the cable hang to the ground. (See the Terminology drawing on Page
3 for the color code of each cable location. See Page 9 for correct bolt assemblies.)
Before raising first beam, Upper ends of cables are snapped to purlins. Upright brackets
and wing eave brackets are installed where needed for Gabled End Frames. (see Hardware
Chart on Page 9)
