Exterior t-astragals generally have a 1/8" wide saw kerf milled into them to accommodate weather stripping. A flat astragal is a profile generally comprised of a half-round circle flanked by two horizontal fillets, they can also be referred to as a small torus moulding. All our flat astragals are in the plant on/applied moulding category of our catalog. We also have some taller sized mullions in this category, browse here for smaller sized mullions. Simply enter the width of the profile size you would like to view, if you're looking for a specific size then enter that size in both the minimum and maximum size boxes provided above.
If by chance you don’t see the design or shape of the t astragal you need, just send us a sketch we be happy to design a cad drawing, cut an acrylic template, and grind a set of moulding knives for any profile you want, thanks for visiting our website.
