Don't be fooled by cheap climbing rope knock-offs! There are many companies following the trend of using rope for leashes. While some may appear to be standard climbing rope material, they are actually cheap alternatives that will likely fail over time or risk breaking while you're walking your pup. Just Pet Products specialize in using only the highest quality of climbing rope from the highest ranked/rated climbing rope brands in the world.
Some history on climbing ropes (if you're curious!): The first climbing ropes were made of natural fibers like sisal (a plant) and manila (hemp fiber), but today they've evolved to much stronger material. Nylon ropes were developed during World War II by DuPont scientist Wallace Carothers, while developing a product that would enable climbers to take on bigger, more daring climbs.
Today's standard climbing rope is kernmantle ropes, which are specifically designed for climbing. Kernmantle ropes are made of two parts: (1) the core and (2) the sheath. Standard dynamic ropes are 50 meters (165 feet) long, with a stretch of 6 to 7 percent (of its length) and commonly made in diameters of 8mm to 12mm.
The Core: The inside of kernmantle rope is made of braided or parallel nylon filaments (like a bunch of little ropes). These filaments form the core and make up approximately 70 percent of a rope's diameter. Rope companies will try to make the core as strong as possible, because the core is really the part that saves your life in a fall.
The Sheath: The outside of kernmantle rope (the sheath) is made of smoother, colored nylon strands that are woven. This construction allows offers more stretch and also protects the core.
Static and Dynamic: Nylon ropes not constructed in a kernmantle design are not suitable for climbing and are called static ropes because they do not stretch. All nylon ropes used for climbing are called dynamic because they stretch.
What is recycled climbing rope? There are many factors that can lead a climber to want to retire his/her rope, including: age, amount of use and amount of wear. Over time, dynamic climbing rope begins to lose some of its give (stretch) and becomes more stiff. This stiffness can cause issues for a climber during a fall, causing a shock to the body. Other climbers may have used their rope once or, in some cases with rope we have purchased, never. While the rope appears brand new, without knowing the age and/or number of climbs we play it safe and consider the rope retired.
Why stick with a cheap $1 nylon rope that large mass retailers will sell you for $15 - $20, when you can have a unique, handmade and high quality climbing rope for only a few bucks more?
