Our Double Flap Keder has two flaps, designed to "sandwich" your fabric material and then it is welded or sewn to your material for a secure hold. Keder is used in both permanent and semi-permanent tents, temporary structures, banners, building wraps, facades, awnings, curtains, and marine products. Double Flap Keder is stocked in Standard Weave, a translucent fabric, Panama weave, a blockout fabric, and Berry Amendment, a blockout fabric, with select options available. Always Made In House.
