Review on 2 E-Track Ratcheting 2x12 Cargo Tie-Down Straps: Secure Motorcycle, Trailer & Pickup Loads by David Jones

Fine print only states that ABF Upack bricks have E-track strips as the only attachment option. Luckily I found this, otherwise it would be difficult to use other mounts. If you're just packing it really tight, you might not need as much as you think. I ended up only using 1 per cube because it was packed so tightly that things couldn't move, but it doesn't hurt to use them anyway to keep it stable while unloading. These straps are really well made and strong, they were a bit larger than I expected but it's certainly good as they were more than enough to hold things in place. I also couldn't find ANY store (tried Home Depot, Lowes and Ace) that had these e-track ratchet straps so luckily I ordered them in time to have them before the cubes arrived.
