These folding ladders are compliant with OSHA's Part 1926-1053 safety requirements for Type II ladders (225 lb. duty rating) They provide access to cleanroom ceiling FFUs and lights for routine airflow measurements or maintenance operations.

The electropolished surfaces are ultra-smooth and wipe-down without snagging nonwoven wipers or generating particulate contamination. Leveling glides are encapsulated in non-particulating, non-outgassing polyurethane.

Why is Electropolishing Critical?
Removes iron and other surface impurities that cause corrosion
Draws chromium and nickel to form a hard, protective finish
Removes irregularities (pits and burs) for an ultra-smooth surface that's easy to clean
