Though
clean-out inspection plates are no new invention, Beckson was the
first to conquer all three safety features. First, a cover that
would not open unexpectedly. Second, maximum watertightness. Third,
prevent jamming closed or cross-threading that would prevent a cover
from being closed. The Beckson Screw-Out Inspection Plate was designed
to provide access without the use of tools, with a single start,
non-jamming (no cross-thread), extra strong, self-cleaning buttress
thread. They incorporate a self-aligning center and an innovative
gasket to assure a watertight seal. A patented back-up sealing wall
leaves the plate waterproof, even if the gasket is removed. A screw-out
plate should be used in compartments where a change in air pressure
due to temperature or oil cannig can occur. These plates also are
used for access, inspection, and clean out for tanks and compartments,
or just as general access for shut-off valves or back-fastenings.
The clear center plates permit observation of controls or guages
and visual inspection without the necessity of removing plate.
