ARMOUR - SUPERED Aluminum Sliding End Barn Door Superstructure - Fully Welded and Assembled Frame – Includes: Galvanized Round Track, Neoprene Ball Bearing Trolley, Aluminum Stop, Pull Handle, Adjustable Wall Mount Stay Roller – LUMBER NOT PROVIDED. Frame Sized for Opening 6’ W x 8’ H. Armour sets the industry standard with its innovative End Barn Door Superstructure. Manufacturing procedures enable owners and builders to install door frames without cranes or multi-man crews. Once positioned, leveled, and plumb, the Superstructure can be filled with locally cut and purchased 2" x 6" lumber (actual thickness of required lumber is 1-1/2"). We purchased this sliding door when we made plans to build our barn. Unfortunately, we had to change the design of our barn - and we were unable to use this door. I was so disappointed! We have $950 in this door - would like to recoup $500. The 1st photo shows the top of the door - still wrapped - in our garage. The 2nd photo is from the manufacturer, showing what the door will look like once you insert the lumber you will purchase (separately - not included). The 3rd photo is also from the manufacturer.
