Ten Important Things You Need to Know About Rope and Bungee

Rope and bungee are two of those everyday items that most of us never give a second thought to.

Here are 10 things you should know about that rope and bungee you have hanging around in the garage.

1) Knotting Reduces a Rope’s Strength by 50%.

Need to knot a rope or cord? Keep in mind that adding a knot to your line reduces it’s strength by about 50%.

2) All Bungee is Not Created Equal

Chances are that bungee you bought at the hardware store or online was made overseas using rubber seconds. What are rubber seconds? Used rubber is chopped up and reformed into strands and pieces, then used for the inside of bungee. Most bungee is manufactured using rubber seconds. Like anything, rubber seconds don’t come close to equaling first quality. At Quality Nylon Rope we use only first quality rubber in our bungee. Always have, always will.

3) Use it For the Application it’s Manufactured for.

Always…always…always use your rope for what it’s intended to be used for. Read the website you purchase from carefully for any notes and disclaimers regarding the rope you purchase. For instance, Quality Nylon Rope has such a disclaimer on each page that reads:

NOT to be used for any kind of personal safety or critical application.

There are companies who manufacture rope and bungee just for critical applications and situations where personal safety are involved. You should always make sure you purchase the right type of rope for whatever it is you want or need, to do.

4) There are Many Different Styles of Rope.

Rope comes in lots of styles. The most common, and what you’ll normally find in the hardware store, is 3 strand twisted. Other common types of rope are solid braid, double braid and diamond braid.

5) UV Rays Wreak Havoc on Rope

UV rays are very damaging to rope and in those situations when you don’t need to leave it outside, it’s always recommended that you bring it in out of the damaging UV rays.

6)  Color affects break strength

Did you know that natural/white rope has a higher break strength than a comparable colored rope?

7) Working Load vs Break Strength

A quick way to get a general idea of a rope’s working load when you have the information on it’s break strength is to reduce the break strength by 90%, leaving you with a general idea of the working load at 10% of the break strength. This quick calculation is not intended to take the place of genuine calculations regarding a rope’s working load. Many factors go into determining the true working load of any rope and this general calculation is not intended to be a substitute for that.

8) Synthetic vs Natural Fiber Rope

Up until about 60 years ago, your only choice for ropes were those made of natural fibers such as sisal and jute. Rope made of natural fiber is inferior in most ways to the synthetic fibers such as nylon and polypropylene, which are prevalent now.  One way natural fibers are better is their grip-ability since synthetic ropes tend to be slippery. Another advantage for those who are environmentally conscious is that natural fibers are bio-degradable, while synthetic fibers are not.

9) Dirty Rope

Most people think of abrasion as occurring when the rope is pulled back and forth against something. While this is one kind of abrasion, another type of abrasion that’s often overlooked is the kind that occurs when your rope gets contaminated with dirt and grime. Once these particles get into your rope they cause abrasion inside by rubbing against the individual fibers. This  reduces the life of your rope so keep your rope as clean as possible.

10) Virtually No Stretch

Sometimes, the only suitable rope for a job is a rope with no stretch. Antennas and other guy lines are examples of situations where the rope must be no stretch. Another complication is that normally these applications are outside, so the rope must also resist the outside elements. An excellent choice in this instance is a Kevlar® Polyester rope. The polyester is used to jacket the outside while strands of Kevlar® or another aramid are inside reducing the stretch of the rope to virtually nothing.

Quality Nylon Rope has several sizes of no stretch Kevlar rope at very reasonable prices.

Differences between Nylon Rope and Polyester Rope

In the world of rope, nylon is king. Most people are very familiar with nylon rope and it’s one of the most commonly used synthetic ropes.  However, polyester rope is actually very similar to nylon rope in a lot of ways, so which rope should you use? What are the differences between them? (Assuming both ropes are the same diameter, of course.)

The biggest difference between nylon and polyester rope is that nylon rope is more elastic and therefore stretches. In fact, it will stretch anywhere from 15 – 25% percent at it’s break point, depending on the application and conditions of it’s use. Polyester on the other hand will normally stretch from 5 – 10%, under the same circumstances.

As mentioned, other characteristics of polyester and nylon rope are very similar. While nylon is a bit stronger than polyester rope when dry, keep in mind that nylon loses some of it’s strength when wet. The range of loss is anywhere from 10 – 20%. When it comes to UV resistance, polyester ropes are somewhat better than nylon. Polyester also has a slight edge in abrasion resistance.

These are some of the things to keep in mind when you need to pick the right rope for your job.

Whatever that job is, turn to Quality Nylon Rope. We have the high quality nylon rope or polyester rope you need for a range of industrial, commercial, and other uses.

 Always keep in mind that the technical information depends on many factors such as how new or old the rope is, how the rope is used, under what conditions it’s being used as well as other things.


Bungee for Kayaks / How to Add Bungee to your Kayak

One of the more common uses for bungee is for use on the kayak deck (front) to hold  things you might need to get at quickly such as a paddle, water bottle, bilge pump etc. No kayak owner considers his kayak complete without that crisscross pattern on the kayak deck.

Here are some easy instructions on how to achieve a very simple layout for your kayak  deck. These instructions are for screw mounting. You’ll need: a 15 – 20 ft length of bungee, a drill with a 3/16″ bit, 4 nylon padeyes, 8 screws to attach the padeyes, 8 washers, a screwdriver, a marking pen and some colored tape to mark where you want  your bungee to go.

This lay out is a box shape with the bungee crossing inside. Lay your tape out in the same shape as the picture below, until you have it exactly where you’d like your bungee laid out on your kayak deck.

Mark the 4 corners where your pad eyes will go. Hold each padeye in place and using your marking pen, make a dot in each eye. Remove the padeyes and drill through each of these holes. Remove the tape.

Place each padeye (along with washers) over the holes and using your screwdriver screw in each padeye, making sure not to drill the screws in too hard.

Starting at the location marked 1 and continuing on to location 2, route your bungee under each padeye in the following order: 1, 2, 3, 4, 1, 3, 4, 2.  Once the bungee has been threaded tie a knot at the end to secure it and cut off the excess. Use a lighter to seal the ends of the bungee.

And that’s all there is to it.

We have several colors of high quality bungee available that you can use on your kayak deck. Our size is in between a 3/16″ and 1/4″ so that no matter which size you normally use, you’ll be able to use ours. Always Free Shipping and lower prices for volume orders.
