Sporting our most popular case size, this intermediate case size is perfect for reasonably sized corner-cut window samples and a variety of window frame components. Locations for a heat lamp, BTU meter, temperature gun, window samples and a variety of window frame components are all included. It also includes space for 2 of our Clear Component Boxes (#KT2320) that can hold all of your smaller items in one convenient container, reducing the need for extra small openings in the foam base. This helps reduce the overall size of your kit. Another great feature is the larger opening to hold a stack of window samples, helping to reduce space requirements again.  That opening can be used for larger frame pieces if not needed for the window samples. The case design includes all of the popular features listed under the other case designs.  This is our most popular selling case!!
