Abstract
An entryway system includes an elongated threshold assembly and a pair of plastic jamb boots attached to the ends of the threshold assembly. The jamb boots have flat level upper faces and a pair of jambs having square-cut bottoms are secured to the jamb boots and extend upwardly from the threshold assembly. A head jamb completes a door frame. The jamb boots may be formed with integral drains that receive water from within the threshold cap channel of the threshold assembly and direct it away from the entryway. The plastic jamb boots prevent rotting and eliminate the need to mill the bottoms of jambs with haunches configured to fit the threshold assembly. Plastic mull post boots also are provided for supporting square-cut bottom mull posts in sidelight or double door entryways.
