stabilizers to which the center drive pipe is attached.
C. Configuration: Rectangular shape with straight bottom and extending across room as indicated
on Drawings.
1. Maximum dimension of stored divider: 2 feet from bottom of structural support to bottom
of rolled curtain.
2. Minimum required clearance between vertical curtain edges and adjacent fixed objects:
6 inches.
3. Minimum curtain height to be 20 feet to keep all electrical components out of reach.
4. Provide 36 inches space between curtain ends and walls or fixed objects to allow
passage space around divider.
D. Operating Mechanism: Drive tube shall be driven by 880 in.-lbs., 14 RPM, 110-120V AC, 60
cycle, tubular motor featuring internal limit switches. Provide number of motors determined by
curtain size and weight. Provide a synchronizer when the curtain has two motors. Provide
motors with a mechanism to counteract the reactive torque forces from the motors and self-
retracting cable reel system to provide power at motors.
E. Curtain Attachment: Suspend upper section of curtain from 1.5 inch top batten, which passes
through a pocket in the fabric. Secure both upper and lower sections of fabric to drive tube
using a plastic spline material sealed inside a pocket. Provide drive tube with extruded grooves
into which spline material slides providing a continuous and secure attachment.
F. Attachment: Attach top batten structural support with beam clamps, hanger brackets, and 3/8
inch diameter threaded rods. Attachment clamps designed to be capable of supporting a
minimum of 5000 lb. each and provided in sufficient number to provide a combined minimum
