Marlow Fast Rope

Fast ropes are designed exclusively for insertion operations. Typically 40–44 mm in diameter, they are made from eight braids of textured nylon or polyester yarn, providing softness and surface friction that enables operators to control descent speed. A thinner 32 mm version is sometimes supplied for users with smaller hands.

Terminations
Several termination types exist, with three main styles:

Lengths & Construction
Standard lengths are based on imperial measures: 15.2 m (50 ft), 18.3 m (60 ft), and 27.4 m (90 ft), with custom sizes available. Construction influences performance: tighter braids produce harder ropes with less compression, resulting in faster descents. Ballast can also be added to rope ends to reduce rotor wash effects.

Certifications
In the U.S., MilSpec MIL-F-44422 is often used. Outside the U.S., manufacturers frequently self-certify against elements of this standard.

Marlow Ropes Development
Marlow, working with UK Special Forces, pioneered the original fast rope design and continues to refine the range for different aircraft, smaller operators, and specialist roles such as descending with heavy loads or dogs. Their ropes are now trusted by tactical units worldwide.

Marlow Fast Rope Features
Marlow ropes use an eight-braid, staple-spun nylon construction. This design offers a supple feel, ensuring descents can be controlled effectively using only hands—common in UK techniques—while reducing the effort needed to brake. Unlike harder braids, this softer construction absorbs liquids, minimising the impact of water or oil on descent speed.

Descenders & Accessories
Marlow ropes are compatible with fast rope descenders. The Marlow Fast Rope Rack is particularly effective, having been designed specifically to complement the rope’s softer braid. Every rope is supplied in a heavy-duty duffel-style storage bag.

Marlow Fast Ropes remain a global benchmark for insertion systems. Their balance of controlled descent, proven durability, and flexible termination options ensures adaptability across training, operational deployment, and specialist tasks.
