Model 109 / high performance roll-up doors for industrial applications

Low Profile Coiling Door for Limited Headroom and Tight Side Clearances

109LP
Marathon’s 109LP high performance roll-up door, with its low profile header and curved panel profile is ideal for applications with limited headroom and tight side clearances.  High speed operation ensures quick entrances and exits for superior access control. Reliable operation means lower maintenance costs and greater over-all security. Insulated slats and high speed operation reduce air exchange, lessen energy consumption and the “stack effect” that can occur in high rise applications.

109G
Marathon’s 109G, high speed coiling grille door is ideal for parking garages, fleet garages, dock areas or any application requiring quick access, security and ventilation. And with no roller wheels, links, bars, tension systems or other high wear parts to replace, the 109G requires less maintenance than a standard roll-up grille style door.
