The Nailor 0800 Series Flat Oval duct access doors are engineered to provide a premium quality, ultra-low leakage door with optimum ergonomics in mind.
…
The unique oval shape was designed after careful study of the needs of site engineering and maintenance personnel. Each door allows a different degree of access, enabling the most appropriate unit to be specified, depending on duct size and likely maintenance requirements. The 0800 Series is available in two frame styles for use with steel duct: a double flange screw hole mounting type (M1) or a knock-over tab type (M2). Both styles come with a simple installation cut-out template which makes the oval shape openings extra easy to cut.
