Durable, High-Quality Glides

Product glides and leveling feet represent the first line of defense against cleanroom contamination. As glides come into contact with cleaners and harsh chemicals, they are often the first component to deteriorate. Terra's glides are durable, chemical resistant, built-to-last, and ISO-rated.

Non-Contaminating Wheels

Polyurethane wheels allow easy transfer of step ladder; noncontaminating polyurethane glides provide no-skid stability when in use.

  • Grounding Chain for Step Stools and Ladders

    12-inch conductive chain attaches to any Terra Step Stool or Ladder to provide ground connection against static discharge.

Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.

    Optional service extension shelf makes room for parts and tools; remove and fold for convenient storage. These ladders are compliant with OSHA's Part 1926-1053 Safety Requirements for Type II ladders.
