Hormann Speed-Master® 4600 L

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.
