- Five Reasons You Shouldn’t Use Bungees Instead of Tie Down Straps
Bungee cords and tie downs are not the same thing!
Using a bungee when you need a tie down strap is a risky scheme at best, and really, just asking for disaster to strike. Do you know why?
- You don’t know the exact strength of a bungee cord.
Most bungee cords do not come with a Break Strength or Working Load rating. Quality cargo straps, however, will have one or both of these important numbers printed on their tag or some other permanent spot on the strap or hardware. No guessing.
- You think using a bungee is OK because you’re "just going a couple blocks."
If a bungee isn’t strong enough to hold the cargo you are carrying, it doesn’t matter if you’re traveling across town or across the country. A skimpy elastic cord may allow a load to shift; once that happens, you risk the safety of surrounding motorists, yourself and your belongings.
- Overloaded or old bungee cords wear out quicker than you think.
It is recommended that the maximum "stretch" of a bungee cord be limited to 50% of its resting length. Even with normal use, these cords eventually stretch permanently, fray or break, or are subject to loose hook-end connections. Exposure to sun, rain, wind and hot or cold temperatures can accelerate a cord’s deterioration, and many experts recommend replacing bungees every six months or once a year, even with light use.
- A metal hook end can straighten, become loose from its attachment point or scratch the items you’re moving.
Just as is the case with not knowing the exact strength of the cord, it is also likely you would not know the strength of the hooks, either. So the potential of failure exists not just with the elastic woven cord but also with the metal hooks. More common, though, is that the hook simply unlashes from the object it was securing.
- A stretched bungee that accidentally slips from your hand becomes a sharp - and really dangerous - projectile.
Enough injuries occur every year when a bungee hook slips from a person’s hand during loading that studies have been performed on the process. The most common injury is to the eyes, with estimates indicating the hook recoils at speeds of 45 to 60 miles an hour. That can do some very serious damage.
Despite all this bungee cord bashing, there is a good and useful application for them, tasks like holding down a tarp or securing the cover on a cooler; but nothing that involves containing heavy, bulky or airborne-prone items.
More massive cargo should be left to heavy duty, high quality tie down straps. They come in a variety of lengths, widths, and Work Load ratings, and many styles of hook ends and ratchet straps are available to reliably perform whatever hauling or transporting job you may have. Use the right tools for the task at hand, and you’ll find that investing in tie downs for dependability and longevity will be more than worth it!
