Custom Sizes Available Upon Request - Additional leadtimes may apply
Unlike the ULtimate Sandwich® style door, the ULtimate II weld on
door requires minimal additional clearance. The duct only needs to be
large enough to accommodate the frame and satisfy the NFPA 96
Standard.
Although the frame only extends 1” past each side of the
opening, the NFPA 96 standard requires a minimum of 1.5”
clearance between the opening and all seams or edges. Therefore, a
minimum of 1.5” clearance is recommended on each side of the
opening. In order to use the minimum duct height, the door must be
installed with its longest dimension running horizontally along the
length of the duct.
