Features and Benefits

High Caliber Hardware

Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. 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.

Hand Rails (Select Models)

OSHA-compliant safety rail extends 30" above the top step; models with extended depth provide convenient work platform.

Convenient Mobility and Safe Stability

All-stainless-steel, non-shedding polyurethane rolling casters, and non-contaminating nylon leveling feet to move and place the ladder with ease. Design free of cracks and crevices where contaminants can collect.
