This has a few features which differentiate it from other Prusik loops: 1. It is rated to 19kN. 2. Aramid fibers make it immune to melting. 3. Hollow construction means it relies on flattening against the line, rather than biting like a thin accessory cord Prusik. 4. Loosens more easily than thin accessory cord Prusiks. This isn't just numbers on a page either: this translates into practice. It's a pleasure to use the Hollow Block and I feel a lot safer with it than any other Prusik system I've used. Review: None better for use with a friction knot. - This thing is a beauty if you're looking for a perfect prusik loop for gripping rope. It works amazingly well on the 7/16" rope I use, slides fairly easily against pulley when slack, and instantly grips like a vise when under tension. Flat surface and weave serves to provide incredible grip under tension. I use it for a progress capture in a 5:1 pulley system hauling very heavy wood up a steep side of a ravine and pulled one long log until it was suspended from the anchor fairly far up a tree trunk and released the pull rope. The heavy load was held entirely by this loop with no signs of trouble. A really great product that's fantastic for what it's designed for. I found myself wanting another, perhaps the slightly longer version, as I have a round prusik with two sewn loop ends that I thought I'd use to anchor the lower pulley against the rope to the load, and though it works, it takes some doing to set the knot. While one of these grips instantly and easily. ## Features - Use as a prusik or Klemheist knot - Hollow braid cord construction - Made in the USA - Powerful gripping ability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0051NARHM | | Best Sellers Rank | #928,906 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,547 in Ropes | | Brand Name | Sterling Rope | | Color | Beige | | Customer Reviews | 4.8 4.8 out of 5 stars (62) | | Global Trade Identification Number | 00846604011451 | | Item Diameter | 6.8 Millimeters | | Item Display Dimensions | 5 x 3 x 2 inches | | Item Length | 13.5 Inches | | Line Weight | 3147 pounds | | Manufacturer | Sterling Rope | | Manufacturer Part Number | SC060TWHB013 | | Material Type | aramid | | Model Number | SC060TWHB013 | | Number of Items | 1 | | Product Style | Classic | | Tensile Strength | 3147 Pounds | | UPC | 846604011451 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Sterling Rope - **Color:** Beige - **Item Display Dimensions:** 5 x 3 x 2 inches - **Material:** aramid - **Style:** Classic ## Images ![6.8mm Hollow Block Loop, 13.5-Inch, Beige - Image 1](https://m.media-amazon.com/images/I/61kCPhq-MIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is clearly better than any of the competing products *by T***R on December 13, 2017* This is clearly better than any of the competing products.

I almost want to take it to the hardware store and test it on straight pvc pipe like the other reviewer said. Unbelievable. Also... when unloaded with the touch of a pinky it becomes unstuck.... wtf? How is that possible. Truly the best autoblock ever. Very happy purchase. *note* I use the wrap around method on my autoblock for rappelling - not the prusik knot. I find it is easier to load and unload without slipping :) Cons: Dirty ropes make it dirty fast. lol 314lb working load? but still 3147lb breaking strength. Maybe I wish it was a little higher? At 175lbs rappelling I'm not likely to come near either. Just interesting to note.A typical sling would be around 22kn or 4950lbs breaking strength ## Frequently Bought Together - Sterling Rope 6.8mm Hollow Block Loop - Climbing Technology RollnLock Pulley, Orange, One Size - Wild Country Ropeman 1 Ascender - Lightweight Rope Clamp for Climbing, Hunting, Tree Climbing, & Rigging --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/15578830-6-8mm-hollow-block-loop-13-5-inch-beige](https://www.desertcart.kg/products/15578830-6-8mm-hollow-block-loop-13-5-inch-beige) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-12*
