GM CLIMBING 8mm Prusik Loop Pre-Sewn 24 in - Durable 24kN Safety Loop

In this review the GM CLIMBING 8mm Prusik Loop Pre-Sewn 24 in is assessed for climbers and outdoor professionals who need a compact, reliable friction loop. The bottom line: this loop is for anyone who ties prusik, autoblock or Klemheist hitches on 11-12.5mm ropes and wants a neat, high-strength sewn loop that handles well and resists abrasion. Its 24kN breaking strength and CNC machine-stitched joint with a heat shrink sleeve are the single biggest reasons to buy if durability and easy inspection matter to you.

Key Features

• 24kN Breaking Strength: Provides a high safety margin for rescue, rigging and recreational rope work so users can rely on the loop under heavy loads.
• Pre-sewn CNC Stitching: Machine-stitched joints stay neat and compact while maintaining strength, avoiding bulky knots that complicate dressing hitches.
• Heat Shrink Sleeve: A transparent protective sleeve covers the stitching so abrasion is reduced and inspection of the seam is easy in the field.
• 100% High Tenacity Polyester: Offers excellent abrasion resistance and low water absorption for consistent performance in wet or dirty conditions.
• 8mm Double-Braid Construction: A round, supple cord that is easy to tie, dress and untie prusik, autoblock and Klemheist hitches on recommended rope diameters.
• Multiple Length Options: Available in 18 in and 24 in lengths so users can choose a size that best suits ascending, backup loops or anchor setups.

Who It's For

The GM CLIMBING 8mm Prusik Loop is aimed at climbers, rope rescuers, arborists and canyoneers who commonly use friction hitches on 11-12.5mm ropes and need a ready-made loop with strong sewn joints. It suits those who value compact gear that is easy to inspect and resistant to abrasion for repeated outdoor use.

Those who should look elsewhere include users who need extremely supple cord immediately out of the package for micro knots or very small-diameter ropes, since some customers report the loop can feel stiffer after initial use. Also, if you require custom splice work or non-sewn terminations, a raw cord option would be more appropriate.

Pros & Cons

Pros

• High 24kN MBS gives confidence for technical and rescue applications.
• Neat CNC machine stitching with heat shrink sleeve improves durability and makes inspection straightforward.
• 100% high tenacity polyester and double-braid construction deliver strong abrasion resistance and low water uptake.
• Compact, light and easy to carry for multi-purpose outdoor racks.

Cons

• Some users notice the loop is relatively stiff after a few uses compared with softer cords.
• Length opinions vary, so choosing between 18 in and 24 in requires considering personal knotting preference.
