GENERAL SPECIFICATIONS: HEAVY-DUTY CURVED TRACK
Provide Model 501C as manufactured by H & H Specialties Inc., South El Monte, CA.
Track shall be 3-1/4" I-beam, with 1-5/8" top, intermediate, and bottom flanges, extruded from mill finish 6063-T5 aluminum. Track
shall be factory curved and provided unspliced in lengths up to 24'.
Suspend track with clamp hanger formed from 1/4" steel. Provide 2' overlap at center, rigidly separated by two overlap clamps.
Where lengths exceed 24', connect tracks with 8" long, two-piece splicing clamp of 1/4" steel.
Provide single carriers, spaced on 12" centers, constructed of two urethane-tired sealed ball bearing wheels fastened parallel to
formed steel carrier body with heavy-duty hook, swivel and trim chain for attachment of curtain. Attach Nylatron wear strips at contact
points between carriers and track to minimize friction and noise. Install neoprene bumpers to carriers to further reduce noise.
Master carriers shall be two connected urethane-tired sealed ball bearing wheel assemblies pivoting on a steel body with arm
extending above track for anchoring operating line with two cord clamps.
Single and double end pulleys shall clamp securely to the top flange of the track and shall be equipped with 6" diameter Nylatron
GS sheaves grooved for 3/8" operating line. Install two sealed 5/8" precision ball bearings in each sheave. Lock shaft to side plate
on head end with 3/16" keeper pin to prevent rotation and install fine-threaded nylon insert lock nut.
Provide floor block in 12 gauge steel housing containing 6" Nylatron GS sheave with two 3/8" sealed precision ball bearings. Sheave
axle shall lock at any point within 9" vertical slots to allow tension adjustment of operating line.
Black operating line shall be 3/8" diameter, stretch-resistant rope with spun polyester outer jacket braided over solid aramid core.
Install guide assemblies to direct the operating line along the top of the track, allowing curves in any direction. Assembly shall
consist of three Nylatron GS guide spools with two shielded ball bearings each mounted to 1/4" steel body and clamped to the top
flange of the track.
All steel components shall be zinc plated to resist corrosion.
FLUSH CEILING HANGER
Steel plate mounts flush to ceiling. Track
clamps to bracket with offset clips. For use on
walk-along tracks only.
No. 531 - Zinc plated.
No. 531B - Black Finish.
No. 50 PIVOT DEVICE

WALK-ALONG MASTER CARRIER
2 single carriers pivot on steel connecting plate
with heavy-duty hook, swivel and trim chain.
No. 502W - Urethane-tired wheels.
No. 502WB - Black finish.
No. 517W - Nylon-tired wheels
No. 517WB - Black finish.
