Warning! What I am going to describe below is only what I have done myself. It is not a recommendation that you should do the same. In fact, most of the pieces I use below specifically include warnings that the pieces should not be used to hold weight overhead, be used for athletics, or used to support body weight. Anything you choose to copy from the following is done at your own risk.
Lifting safely by yourself has been a popular topic lately. This was brought to my attention quite directly under the weight of a 400 lbs squat attempt a couple weeks ago. It was further reinforced by a 70’s Big post and a video that has been making its way through social media recently:
While I typically pride myself on taking appropriate safety measures, the squat attempt a couple weeks ago revealed a flaw in my setup. When I missed the attempt, the bar dropped on my safety straps and bent open the quick links, catastrophically. While I frequently record my lifting attempts, unfortunately I did not record this one, and so I only have a picture of the aftermath. The good news is that the pin & pipe safety system survived with hardly a scratch.
Failed Safety Straps due to…
Broken Quick Links
The pin & pipe safety system is likely the strongest, but when the barbell comes into contact with it, a couple things happen. First, the bar comes to an abrupt stop and/or bounces, particularly if one side hits before the other. This can be quite jarring. Second, when that impact occurs, if it is of sufficient force, it will mar the knurling on the barbell. I paid a decent price for my bar, and I’d like to keep it in the best shape I can.
I prefer straps because they take up slack more smoothly on a squat that goes a little deeper than planned, and because they do not mar the knurling on the barbell. I still believe my original strap system is safe and effective, with the exception of using master links in place of the quick links. The quick links were used in the mistaken belief that they were rated for enough loading force, and because they would allow for a fast transition from the bench position (lower) to the squat position (higher). This design is incredibly cost-effective, especially when compared to the commercially-available alternatives that start around $165.
The Original Safety Strap
The original strap system could have been corrected by simply replacing the quick links with threaded master links, but it still had one fundamental flaw for my garage gym: it was the wrong color. So, I set out to make a reasonably-priced strap system that would out-perform the first system, preferably in orange.
Here’s what I came up with. I started with four axle straps ($4 each, rated at 3,300 lbs). I used 3/8” clevises ($4 each, rated at 2,000 lbs) to connect to a master link ($2.50 each, rated at 1,980 lbs). The master link connects to one loop of a tree saver strap ($24 each or orange, as low as $14.50 each for yellow, rated at 20,000 lbs). The other end of the strap connects to 5/16” Grade 30 chain ($15 for 7 feet, rated at 1,900 lbs) using another 3/8” clevis.
Safety Straps with Labels
Since a chain is only as strong as its weakest link, that means my entire system is rated for 1,900 lbs per side, as limited by the chain. I don’t know about you, but it’ll be a while before I squat 3,800 lbs! And the price isn’t too bad at $110, total. If I was willing to settle for yellow straps, I could have knocked the price down to $90.
Strap Adjusted for Rack Pulls, Squats and Bench Press
I replaced all of the clevis cotter pins with hair pin clips for easier adjustment. And because I’m crafty like that, I added paracord lanyards to the clevis that will adjust the strap position for rack pulls, bench pressing or squatting. The lanyards make the clips easier to see and easier to remove.
Hair Pin Clip with Lanyard
In closing, I prefer straps as the primary safety method, but I recommend setting the pin or pin & pipe safeties as a redundant back-up, just in case. In the end, can you really put a price on the life or limb you risk in the gym?
