The Military Compact Descender® (MCD®)
The Military Compact Descender® (MCD) is a Personal Lowering Device engineered for military safety and operational environments. Designed for simplicity and control, the MCD enables operators to descend using one hand—freeing the other for mission-critical tasks.
Operational Advantage
Field tested for 20+ years, the MCD is designed for deployment in environments where controlled descent or emergency egress is required, including elevated work and high-risk environments. Its compact, self-contained design ensures it can be carried by personnel and deployed without reliance on external systems.

Rooted in the mission of saving lives.
Inspired by the tragic events of September 11, 2001, Diane Waghorne felt a profound calling to develop safer ways for people to evacuate from perilous situations. Her research led her to a device designed for emergency descent in dangerous conditions. Recognizing its life-saving potential, Diane acquired the patent for the Military Compact Descender (MCD) and brought its manufacturing to North Texas.
Driven by her passion for incident prevention and her unwavering commitment to safety across all industries, Diane established Tech Safety Lines (TSL) as a trusted leader in rescue solutions.
Today, Tech Safety Lines operates from two training centers in the Dallas–Fort Worth area, with more than 50,000 rescue kits deployed in over 35 countries worldwide.
