Type PCM & PDCM single and double leaf access doors (single leaf shown) incorporate several innovative features which reduce the amount of labor required to cast the door into a concrete vault. To simplify installation on a standard concrete vault form, doors are designed with a 6" (152mm) high frame (other frame depths available) and have no vertical projections below the frame. Doors are constructed of aluminum and feature a peel off covering to protect the door finish during the pouring process.
