Buy This!
Size: Medium 16in x 1in
Super heavy duty! Not only does the magnet hold a ton, the strap is totally adjustable to hold wide items. Currently it's holding an 8 ish lb rope on the side of my garage fridge with zero issue! Easy to use and works great!

"Keep On Holding On" assist.
Size: Medium 16in x 1in
Magnet is powerful indeed . The velcro strap is quite long and I have not figured out how to shorten it without cutting it. Great for hoses, ropes, and pull alongs. Temporary use as hold down in a truck bed for lite items.

Awesome!
Size: Large 24in x 1.25in
These straps are exactly what I needed! I got them to hang my extension cords in my truck and they worked so well, I got three more to hang my water hoses in my truck also!
