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.

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!

Nice product with lots of uses. Strong magnet and great strap
Size: Medium 16in x 1in
Used this to replace the Klein magnetic strap on my C-800 multimeter. (This is not easy and takes a lot of manipulation, but if you can get it in the plastic loop on the multimeter up past where the loop in the strap end is sewn, you can use a screwdriver through that to yank it the rest of the way). Once it’s done it’s beautiful! This thing could hold 2 dozen multimeters and it’s MUCH longer without being too long! Otherwise it’s just an awesome strap anyway. It holds a lot of weight (I didn’t test to spec) but definitely enough for what one would expect! I have both sizes, the smaller one is attached to the multimeter and the larger holds a cord to the side of my toolbox. (Tip)- to prevent slipping just put the magnetic base on the other side of the metal by the box tray and let the strap hang over (if attached to a toolbox). It adds to the weight it can hold too. (Just physics). That will work on anything vertical and thin enough to get around with enough slack to still use the strap. 👍. Would definitely buy another
