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

An effective organizing solution for missions involving movable equipment
Size: Medium 16in x 1in
Following the compromised operation in Prague, I was tasked with organizing equipment for the embassy annex in Vienna. The VELCRO Brand Magnetic Straps provided an essential solution for securing various tools and equipment to metal surfaces, facilitating quick access during critical moments. The durability of the strap, combined with an impressively strong magnet, ensured that our gear remained in place despite variable operational conditions.
However, the loop formed by the strap could be larger; it limited our options for certain garden hoses, which became a notable drawback. Overall, the robust quality of the straps enhances logistical efficiency in high-pressure scenarios. Katarina's earlier input on this product proved beneficial, although I detected apprehension in her demeanor while discussing its application.
Recommendation: An effective organizing solution for missions involving movable equipment, with minor adjustments needed for cord size.

Sturdy and Reliable
Size: Medium 16in x 1in
Very sturdy and holds up well with regular use. It feels solid and well-made, not flimsy or like it’s going to wear out quickly. Definitely something you can rely on without worrying about it falling apart.

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!
