The Jammy : a versatile loop for all rope diameters

The BEAL Jammy is designed to fit all rope diameters, on one strand or two. It comes in three different sizes: 35 cm, 50 cm, and 60 cm. Its flexible aramid cord with a polyamide sheath allows it to grip effectively even on small-diameter ropes. Ideal for creating auto-blocking knots such as the Prusik and Machard, this loop offers you a quick and reliable solution. Certified EN566, the Jammy adapts safely to a multitude of activities.

Unmatched strength and lightness thanks to Technora technology

Made with Technora aramid, the Jammy ensures exceptional strength of 22 kN, even in cases of significant heating due to friction. Its robust construction resists repeated bending, allowing you to perform maneuvers without concern for premature wear. Its heat-shrink sheath protects the stitching and contributes to its incomparable lightness compared to mechanical systems. With a weight of only 20 grams for the 35 cm version, it becomes indispensable for all climbers seeking simplicity.
