It's not really Velcro, as it is not a "hook and loop" type of thing with a fuzzy fabric.
Basically, both sides are plastic, and are identical. The plastic "spikes" stick into each other and hold quite strongly. I need a bunch of it, but am struggling on what it's actually called.....difficult to search for it without knowing the name. Help?

This stuff is actually double hook, not hook/loop.

I think your looking for 3M "dual lock"

if you're looking for some really strong stuff, Velcro made some hook and loop fabric at its Manchester out of stainless steel for use on the space shuttle

DualLock is the best stuff ever.

I use it for pedal board tape. Just remember that if you want something to be removable you must:

1) use less than you think
2) use a dull-edge flat tool (like a Spackle knife) to separate the bond.

It's more like legos than it is velcro. The way it snaps together is very satisfying.

Keep in mind Velcro is a brand, that's made by YKK the company that makes really good zippers.

Hook n'Loop is the generic, easy to reference, name for 'velcro like' fabrics.

I've seen stuff made out of a stiff plastic that was really strong.

Yep, Dual Lock. It's good stuff.

Thank all of you for the replies. Did a quick search, yes that’s what I was looking for. Order placed! Mods, feel free to delete this thread if you wish.

Dual Lock and they make in varying strengths rated in PSI.
