The Pease Fiberglass Door. Replace just your door slab and keep your existing jambs and brickmold. A perfect replacement for Pease (carbon & steel) doors as well as most entry doors by Stanley, Taylor, Mastercraft, Perma Door, Castlegate, Masonite, Therma Tru, Jeld-Wen, Plastpro, and many others. Please make sure to check your measurements (door height, width, and thickness) and feel free to contact us with any measurement or fit questions. Flush (also known as smooth or without traditional embossed panels) is a great option if you need to install glass that requires a non-standard cutout that wouldn't align with typical panel spacing (e.g., ovals, etc.)  Additional glass options can be found in our door glass section. This door is also a great choice for homeowners who require a large pet door to be installed without interfering with door paneling.
