Model 109LP

High Speed Roll Up Door - Low Profile


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.
