Formed edges to be welded together and inter-locked under tension with a roll-formed oval crown locking bar, mitred, welded and ground smooth at the corners. Honeycomb to have a maximum 25mm (1") cell size with compressive strength of 31 pounds per square inch.

Pilasters:

Shall be 32mm (1.25") thick with cover sheets not less than 20 ga. (0.9mm). Pilaster tops shall be reinforced with 20 ga. channel to create extra strength and twist-free rigidity along with minimizing damage by handling and/or shipping.

Headrail:

Shall be 25mm (1") by 41mm (1.625") extruded anodized aluminum with double-ridge anti-grip design. Wall thickness to be 1.5mm (0.060") and shall be securely attached to wall and pilasters with

All panel and pilaster brackets and all door hardware shall be chrome plated zinc die castings. Doors shall be equipped with a gravity type hinge mounted on the lower pilaster hinge bracket. Door hinges shall be wrap-around style and adjustable to permit the door to rest at any position when not latched. Each door to be fitted with a combined coat hook and bumper and a concealed latch, with face mortised flush with edge strip of door. Barrier-free doors shall include thumbturn lever to activate latch without fingertip grip application.

To cover the sightline gap at door hinge side, full length extruded aluminum filler channel shall be provided.

The "no sightline" continuous stop and hinge filler shall be powder coated to match door and pilaster finish. Door top hinge pin shall be made from high strength, self lubricating nylon with a split-tip design to prevent rising out of top door casting. Pilaster shoes shall be a welded one-piece design made from polished stainless steel. Two-piece shoes that can disassemble when kicked are unacceptable.

FINISH

All sheet metal to be thoroughly cleaned, phosphated and finished with a high performance powder coating, electrostatically applied and oven cured to provide a uniform, smooth protective finish.
