Beckson’s Screw-Out access plates are designed to provide access without the use of tools. Screw-out plates should be used in applications where changes in air or back pressure may occur.
This inspection port has a single non-jamming (no cross thread), self-cleaning buttress thread and self centering lid combine for a fluid tight seal without cross threading. The clear center plates permit observation without the necessity of removing the center.
All plates come standard with a gasket. Includes 6 stainless steel screws.
