SPECIFICATION

Curtain

The manufacturers construct the curtain of horizontal sections of the full width, concealed 5/16” (8mm) diameter rods spaced at 2 1⁄2” (64mm) high on center by 5/8” (16mm) x 3 1/8” (79mm) vertical links spaced at 9” (229mm) intervals. Additionally, the covering on all horizontal rods is 7/16″ (11mm) diameter aluminum horizontal spacer tubes leaving 2 1/16″ (52mm) spacing between lines.

Support Structure

• 3” (76mm) X 3” (76mm) structural tubes with 0.120 (3mm) wall thickness furnished by MobilFlex to be pre-drilled and tapped for guides and endplates. In addition, lines will attach to the floor slab and joists above. The attachment at the top is for lateral support only.
• Provide 2” (50mm) X 3” (76mm) steel angles for the face of the wall installation. (instead of steel tubes).
• 4” (101mm) X 4” (101mm) structural tubes (for openings over 250 sqft (2.3m2)) .

End Plates

Furnish steel plates not less than 3/16” (4.7mm) thick (with dimensions appropriate to coil size) to support the ends of the barrel assembly with sealed, self-aligning shaft bearings. Also, end plates bolted to support tubes.

Barrel

A minimum 6 5/8” (168mm) diameter X 0.156 (4mm) wall steel pipe barrel is made to carry curtain load with a maximum allowable deflection of 0.03” per foot of closure width (2.3mm per linear meter in width). Moreover, the barrel houses a torsion spring counter-balance assembly to counter-balance the curtain.

Counter Balance

Oil-tempered, helical torsion spring(s) pre-lubricated and secured around a continuous, solid, cold-rolled steel inner shaft will counterbalance the barrel. Furthermore, the post will bear on self-aligning, permanently lubricated ball-bearing assemblies. Also, the manufacturers make the counterbalance assembly for a minimum life of 20,000 cycles. You can add tension to the Spring by attaching an accessible charging wheel.

Manually Operated

For standard closure, you must manually operate the push-up, and pull it down with a removable retrieval rod. The effort to raise or lower the closure shall not exceed 15 pounds (7kg) force. (Optional but not recommended, hand chain hoist or hand crank with removable crank handle). Motorized operation is better suited for closures with an area greater than 150 sqft (14m2).

Electric Motor Operator

The motor operator shall be industrial duty, jackshaft hoist type. In addition, the primary reduction shall be a heavy-duty belt drive with chain-and-sprocket secondary reduction. Also, the mechanism will self-lock when you apply torque to the output shaft. The operator shall have an adjustable, torque-limiting friction clutch. The motor operator will have a built-in interlock that will prevent damaging the grille if you operate it electrically when in the locked position.

Emergency Egress Release

Supply a flush manually activated emergency egress device to disengage the motor in an emergency.

Electric Key Switch

Control station (when applicable) shall be in two positions, open/close, constant pressure type for flush mounting, housed in a tamper-proof enclosure (key switch to replace push button set).

Guides

Vertical curtain guides are to be of extruded aluminum 1 5/8” (41mm) wide x 2 3⁄4” (70mm) deep with a nylon brush seal to allow smooth operation. We will install top stoppers on each guide to stop the curtain’s upward movement at a secured position.

Bottom Bar

Heavy-duty extruded aluminum section, bell-shaped to provide reinforcement. Also, the bottom bar is to house the lock mechanism. The Center lock mechanism is a 2-point deadlock that activates 7/16” (11mm) steel lock bars at each end. Standard MobilFlex cylinders are operable from one or both sides. Removal of the bottom bar is not necessary to change the cylinders. For counter closures, the bottom bar is to be of extruded aluminum 1 1⁄4” (32mm) wide x 3” (76mm) high.

Cylinders

The locking bottom bar will have a MobilFlex 1” (2.5mm) 5-pin mortise cylinder.
Please choose:1 a cylinder (inside or outside) or
Two cylinders.

Material & finish

Standard aluminum 6063-T5 shall be a clear anodized finish or acrylic paint white or black.

Hood

Supply a 2, 3, or 4 sides (please choose) 0.032” (0.8mm) transparent anodized hood to cover the barrel and rolling grille.
