High Performance Grilles are designed for 300,000 cycles usage with an approximate average operating speed of 24 inches per second to open and 12 inches per second to close. They are well suited for parking garages and other applications where traditional roll-up grilles do not adequately meet the demands for very high frequency usage or the desire for higher speed operation.
Model PG features a springless barrel design, enhanced heavy-link aluminum grille curtain, innovative hinged steel guide system with replaceable UHMW wear strips, 2 HP motor operator with variable speed controller and soft start/stop, dual monitored sensing systems, and more.
Isolation mounts are available as an option to reduce vibration and operating noise transmitted to the structure.
The Model PG is a truly high performance Grille Door – designed to operate for 300,000 cycles Plus an average operating speed of 24 inches per second to open, 12 inches per second to close
|Traditional Rolling Door*||Commercial Doors Direct Model PD High Performance Door||Commercial Doors Direct Model PD ADVANTAGE!|
|Cycle Life||50,000 cycles||300,000 cycles||Designed to last 6 times longer|
|Warranty||2 years / 50,000 cycles||2 years / 300,000 cycles**||Superior performance… superior warranty|
|Barrel Design||Torsion springs||Spring-less design||No springs to wear out or break – eliminates cost of barrel repairs and resulting down time|
|Grille Curtain Links||3-hole links (single 1/8" thick links alternating with double 1/16" thick links||2-hole heavy links(all links 3/16" thick)||Thicker links better withstand repeated coiling of the curtain on itself; Shorter links are more resistant to bending|
|Grille Curtain Rods||Spaced on 2" centers||Spaced on 1 1/2" centers||Rods are closer together for greater strength and increased security|
Aluminum sleeves on every 6th rod, and on every other rod between end links
Aluminum sleeves on every 4th rod; Stainless steel sleeves on every rod between end links
|Sleeves are closer together for more strength; Stainless steel sleeves provide superior wear surface where curtain travels in the guides|
Cotter pins on ends of sleeved rods; Retaining rings on ends of other rods
|Cotter pins on ends of all rods||Ends of all rods are mechanically secured to better maintain curtain alignment.|
|Guides||1/8" thick extruded aluminum channels with HDPE wear strip inserts||
1/4" thick steel shapes with replaceable UHMW wear strips; Hinged and removable outer guides / removable inner guides
|Steel guides are more durable than aluminum; UHMW wear strips won't wear out; Hinged outer guides provide easy access for periodic inspection and maintenance|
|Guide Mounting||Steel wall angles||Steel wall tubes||Wall tubes provide more rigid mounting for very high frequency / high speed use|
|Motor Operator||1/2 HP in-line gear drive motor operator||2 HP high efficiency in-line gear drive motor operator; Variable speed controller with soft start/stop feature; Integral speed governor||Complete assembly is designed specifically for very high frequency / high speed use; Variable speed allows grille to open fast but close at slower, safer speed; Soft start/stop extends life by slowing grille before full open and close to reduce shock loads; Governor prevents curtain free-fall in unlikely event of operator component failure|
|Operating Speed||Approx. 6" to 8" per second to open and close||Approx. 24" per second to open, 12" per second to close||Opens 3 to 4 times faster and closes 1½ to 2 times faster than traditional rolling grilles – plus enhanced safety features are included|
|Price Guarantee||NOBODY BEATS OUR PRICES If you find a lower price from another online store, we will match the price and refund 10% of the difference.|
|Cost***||Superb value –6 times the life for about 2 times the price of a traditional rolling door!|
