| Product Features | Traditional Rolling Door1 | LAWRENCE Model PD / PI High Performance Doors | LAWRENCE High Performance Door ADVANTAGE! |
| Cycle Life |
20,000 cycles | 500,000 cycles | Designed to last 25 times longer |
| Warranty | 2 years / 20,000 cycles | 2 years on door – 5 years on motor operator / 500,000 cycles2 | 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 |
| Curtain | Interlocking single slats or insulated slats with pressure-fit back cover; Endlocks on alternate slats | Interlocking single slats (Model PD) or insulated slats with fully interlocking back slats (Model PI); 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 spaced across curtain reduce finish wear and operating noise |
| Guides | 3/16″ thick formed steel U-channels | 3/16″ thick oversize steel U-channels with replaceable extruded UHMW wear strips | Oversize guides provide better operating clearances at higher speed; UHMW wear strips reduce friction and curtain wear |
| Wall Angles |
3/16″ thick steel wall angles | 1/4″ thick steel wall angles | Heavier wall angles 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 |
| 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 1 1/2 to 2 times faster than traditional rolling doors – plus enhanced safety features are included |
| Cost3 | $ | $$$ | Superb value – 25 times the life for about 3 times the price of a traditional rolling door! |
