|Product Features||Traditional Rolling Door1||LAWRENCE Model PD High Performance Door||LAWRENCE Model PD ADVANTAGE!|
||50,000 cycles||500,000 cycles||Designed to last 10 times longer|
|Warranty||2 years / 50,000 cycles||2 years / 500,000 cycles2||Superior performance… superior warranty|
||Torsion springs||Spring-less design||No springs to wear out or break – eliminates cost of barrel repairs and resulting down time|
|Curtain||Interlocking single slats or insulated slats with pressure-fit back cover; Endlocks on alternate slats||Interlocking single slats or insulated slats with fully interlocking back slats; Endlocks on alternate slats plus delrin end blocks on every 4th slat; Scratch-Guards finish protection system||Same high-quality single slats; With insulated slats the backslats are fully interlocking making any slat separation virtually impossible; Delrin end blocks reduce friction if curtain shift should occur; Scratch-Guards across curtain reduce finish wear and operating noise|
|Guides||3/16″ thick formed steel U-channels||1/4″ thick steel shapes with replaceable UHMW wear strips; Separately removable outer guide plates and inner guide angles||Thicker guides are more durable; UHMW wear strips reduce friction and curtain wear; Unique guide design provides easy access for periodic inspection and maintenance|
||Steel wall angles||Steel wall tubes||Wall tubes provide more rigid mounting for very high frequency / high speed use|
|Motor Operator||1/2 HP minimum in-line gear drive motor operator||2 HP minimum 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 door to open fast but close at slower, safer speed; Soft start/stop extends life by slowing door before full open and close to reduce shock loads; Governor prevents curtain free-fall in unlikely event of operator component failure|
||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 1 1/2 to 2 times faster than traditional rolling doors – plus enhanced safety features are included|
|Cost3||$||$$$||Superb value – 10 times the life for about 3 times the price of a traditional rolling door!|
