The Curb Outside Dimension (COD) is a critical piece of information for the ordering process. This will be the dimension of the unit that will be the base for the skylight or smoke vent. Compare this to a shoe box and the lid for the shoe box.  The COD would be the dimension of the shoe box that must fit inside the net frame inside dimension (NFID) of the skylight or lid of the shoe box. The COD is typically one inch (1”) smaller than the NFID. The COD should include any flashing materials and would be the finished and flashed dimensions of the curb. The typical curb wall is 1.5” thick, unless otherwise specified.  This dimension is critical for every installation and therefor the critical emphasis throughout the ordering process.  We look forward to serving your daylighting needs.

The NFID is typically one inch (1”) larger than the curb outside dimension.  This dimension is critical for every installation and therefor the critical emphasis throughout the ordering process.
