Chem-Pruf Door Frames

Precision engineered, color-matched FRP frames are the perfect compliment to your Chem-Pruf door. All internal components are non-organic and completely encapsulated, leaving a frame that is free of cavities, exposed reinforcements and fasteners. Additional reinforcements can be placed in the mold cavity and electric components can be added to easily accommodate all specialty hardware. Chem-Pruf frames are perfect for existing wall conditions and single frames purchased with hinges are fully assembled, easy to install, repair and maintain, plus they require no painting or finishing.
