Bulldog-tough panel. Recommended for exterior or interior door openings up to 33’0″ wide x 30’0″ high or 690 square feet, the Speed-Master® 4600 L is constructed of patented, interlocking aluminum hinges which act as integral windbars, creating a sectional panel design that provides panel stability and increased wind resistance. Sliding the panels apart without removing the entire door or roll assembly allows for inexpensive replacement, and a full-width vision area provides unobstructed viewing. Since the Speed-Master® bottom bar consists of few parts, does not support a tensioning system, and requires less repair time, it can be replaced at a lower cost than comparable products.
Special 5 & 2 warranty. Demanding industries such as manufacturing, mass transit, warehouses and waste management facilities will benefit from the simple and reliable design of the Speed-Master® 4600 L. Design advantages such as zero moving parts within the guide tracks and direct-drive motor, support minimized maintenance for the walk-away dependability busy operations desire. Our exclusive 5 & 2 Warranty is our promise to you that you can count on our doors to perform according to your standards for many years to come.
Low-profile guide tracks with built-in light grid. The Model 4600 L has low profile heavy duty steel guide tracks that contain an 8’0″ high light grid as standard. The light grid allows for automatic reversal of the panel and eliminates the use of a coil cord. It also eliminates the need for a panel reversing edge, which is typically vulnerable to damage, resulting in a reduction in maintenance and downtime. Full perimeter draft seals provide dust and odor containment as well as general environmental control.
