Mechanical Friction Devices for Arborist Climbing

Mechanical friction devices replace traditional prusik hitches with engineered systems for controlled ascent and descent. Designed for professional tree work, these devices provide consistent friction management and smoother rope handling compared to tied hitches.

All products in this range are CE certified and intended for use with EN 1891 Type A climbing ropes, typically between 11mm and 13mm in diameter.

We stock mechanical devices from trusted manufacturers including Petzl and Notch, suitable for both moving rope systems (MRS) and stationary rope systems (SRS). Whether climbing doubled rope or single line with an auxiliary brake, these systems deliver predictable performance with reduced effort and improved efficiency at height.

Compatible with EN 1891 Climbing Ropes

Mechanical friction devices are designed for use with low-stretch EN 1891 Type A climbing ropes, typically between 11mm and 13mm in diameter. Correct rope compatibility is essential for safe operation and optimal performance. Always refer to manufacturer guidance to confirm approved rope diameters and system configuration before use.

This compatibility makes these devices ideal for professional arborists using modern climbing lines in both moving and stationary rope systems.
