Innovative designs. Unmatched quality and dependability. Unparalleled customer service. Since bursting onto the market in 1963 with a handful of thoughtfully engineered products designed for climbers and mountaineers, these three core principles are what has set CMI apart.

Today our line includes products designed with a wide variety of uses in mind. Our close partnerships with arborists, ropes course professionals, and fire service and industrial safety experts have enabled us to develop elegant solutions to the unique challenges these professionals face.

While our ever expanding dealer network may span the globe, we at CMI have never wandered from our home in West Virginia's outdoor playground. Our setting near the world renowned Seneca Rocks and New River Gorge climbing areas helps us stay focused on our core principles and the products we stake our lives...and our name...on.

Double Duty

The Twin Expedition is the first single-handled dual ascender designed to meet the needs of industry leading arborist professionals. The EXPTWIN easily accommodates three rope techniques - 2:1 doubled rope technique (DdRT), 1:1 single rope technique (SRT), and 1:1 twin line ascent (DbRT). It is intuitive and easy to use, has redundant safety features, and is the first ascender on the market to use one finger to actuate both cams for one handed downward adjustability.
