Woodfold's H3100/ H4100 Acoustical Folding Partitions (STC 31/ 41)
are of semi-rigid laminated construction with manufacturer's
standard vinyl covers providing wrinkle-free impact resistant
surfaces. Covers have steel strips laminated within each fold for
acoustical purposes. Covers have multi-ply sweep strips top and
bottom both sides of the partition for an acoustical seal.
The top sweep strips are 1/2 inch (13 mm). Partitions have an
internal framing of 14 ga. (2 mm) half hard steel riveted to form
"X" construction pantographs.
Pantographs provide an even extension and contraction without
binding on straight runs of track as shown on the plans.
Pantographs have built-in stops to prevent over-extending.
Partitions have pantographs located at top and bottom, plus
intermediate pantographs located no more than 4 feet (1219
mm) on center for heights over 8 feet (2.438m). The standard bottom
sweep strips are 1-1/2 inches (38 mm) with 2 inch (51mm) alternative option.
The lead post is trimmed with clear anodized aluminum and
include mechanical latching.
