Using Cam Buckles Safely

Buckles

Truck owners and all those who have ever had to transport large loads know how very important it is to make sure cargo is secured on the road. The safety of other drivers can be jeopardized if care and attention aren’t given to the preparation of a load. Fortunately, there are many combinations of metal hardware and straps made from various types of webbing that can be used to provide optimum security. Today, we’ll look at one type of hardware in particular – the cam buckle.

Like ratchet straps, cam buckles are excellent for securing cargo. However, there are some potential dangers associated with their misuse. Because cam buckles are tightened by pulling on the strap, rather than with a ratcheting action, straps can only be tensioned as tightly as the users strength allows. Still, this tightening method does make it less likely that the user will over-tighten and damage the cargo.

Cam buckles are considered ideal for securing cargo onto pallets, trailers, or into trucks, as well as for use around the home, shop, garage or farm. Endless cam buckle straps have one piece designs that make them easy to use and store.

Using Cam Buckles Correctly

  1. Hold the buckle in one hand, and hold the webbing in the other.
  2. Press down the lever on the buckle with your thumb.
  3. While the lever is depressed, insert the webbing into the buckle opposite the thumb lever.
  4. Feed the webbing through the buckle without releasing the thumb lever.
  5. Pull the loose webbing to the desired tightness.
  6. To loosen the cam buckle, pres the thumb lever and pull the end of the webbing that is not loose.

Cam Buckle Safety

  • When using cam buckle straps to secure a load, check the tightness of the strap every 20 to 30 minutes.
  • Safe working capacity is 1/3 of the breaking strength. Under no circumstances should you exceed safe working capacity. Adding number of tie downs will not increase the load capacity.
  • Don’t use cam buckles for towing, lifting or personal restraint.
  • Inspect webbing and hardware regularly for signs of wear. Replace product if webbing is damaged, cut or worn.
  • For tie downs with load capacities greater than 500 lbs, use two pairs of tie downs. One pair should be positioned at the front, and another should be positioned in the rear.

Cam buckles can be very useful in securing loads, as long as they are used correctly. Make sure you understand regulations for safe use before using straps or buckles of any kind for load security.

How to Replace Sunglass Lenses

If you’re anything like me, you’ve broken a pair of sunglasses or two. I can’t explain why or how. They go into my purse and they come out cracked and scratched. It’s like there’s a small family of vicious porcupines that only appears when my purse is zipped shut. Whoever they are, they’ve certainly caused me a little frustration over the years and cost me a fair bit of money in replacement sunglasses.

Fortunately, I recently discovered that busted up sunglasses don’t necessarily have to be replaced. In fact, they just need a good pair of replacement sunglass lenses. I’m not going to tell you just how many times I’ve had to replace sunglass lenses, but I am going to share a little of my sunglass lenses replacement experience with you. It is without further ado that I present to you, How to Replace Sunglass Lenses, by somebody who knows.

How to Replace Sunglass Lenses in Plastic Frames

Let’s get this one out of the way quickly, because it’s definitely the more difficult of the two processes. I recommend soaking your glasses in warm soapy water for about 30 seconds before you start trying to extricate the old lenses. It seems tempting to soak them longer, but that doesn’t seem to help. After they’ve been soaked, try pushing the lenses out through the front of the frames. If you’re really unable to get them free, try using a small hammer to break the lens.

The tricky part is installing the replacement lenses. Align them on the top first, and then try snapping them in place, working in a circular motion around the outside of the lens. Once you think everything is in place, take a second to confirm that the lens is properly aligned.

How to Replace Sunglass Lenses in Metal Frames

This is seriously lightyears easier than replacing the lenses in plastic frames. Look for the screw on the underside of the joint where your frames and arms connect. Loosen it up so that the frames have a little give to them. I don’t recommend removing it all the way, since those screws are so easy to lose. Loosening it up should make it pretty easy for you to wiggle out the old lenses, anyway, so save yourself the hassle. Once you’ve taken out the old lens, align the new one, squeeze the frame so that it’s also aligned correctly, and tighten the screw back up.

If you’re not sure that you can handle the responsibility of replacing your own lenses, some aftermarket providers will let you send in your glasses so they can install new lenses for you. It does cost more, but some people feel that it’s worth the trouble, especially for plastic frames.

Replacement sunglass lenses have certainly helped me out on more than a few occasions, and I’ve even gotten to a point where I keep a set of polarized lenses around that I can swap in for long drives. I’m always surprised that more people don’t use replacement lenses, but I’m sure the word will get out soon. They’re definitely worth it!
