Limited space in the apparatus bay can be concerning but with Door Engineering’s new inside-out design it is no longer an issue. The Four-Fold XT operator is interior mounted while the door panels fold to the exterior. This eliminates the bay space that is needed with the regular Four-Fold design.
The Four-Fold XT door system is still built with all the benefits of our standard Four-Fold door. The heavy-duty design and construction of our Four-Fold door enables it to function under high cycle and other severe conditions which create chronic service and maintenance problems for the conventional door alternatives. This new design also maintains the high speed operation and opens horizontally in less than seven seconds!
