Is this a fairly new technology or has it been around a long time and I’ve just never seen it before? I think it’s a pretty interesting design; it looks like it doesn’t wear out as quickly as regular Velcro and I like the little feedback click it makes to confirm it is locked together. Has anyone seen these before?
A friend of mine who went to school at Kent State in the 80s tells a story about lining a guy’s door jamb with the stuff. Maintenance had to remove the door with a sawsall…
Industrial Design is a “practice”, just like being a physician, or a lawyer. There’s always something new to learn; a material, a process, a fastener.
So, a commercial, steel-frame, door “jamb” is roughly .5" wide; a door is 84" tall, and 36" wide; so 84+36 x .5 = 60 sq. in. of “jamb” (discounting the 84" side adjacent to the hinge because it has so much more leverage than the “far” side).
With a dynamic tensile strength approaching 31 lb/sq. in x 60 = 1,860 pounds of “push” to open that door.
Didn’t ya just love being in school!! Reminds me of when some guys at Purdue welded the physical plant locomotive to the rails with a thermite flare.
You mean ‘a new type of hook-n-loop’. Velcro is a registered trademark, like Band-Aid.
And I agree, that is the best hook-n-loop I’ve seen. If you look at it closely, you’ll notice a very cool cross section and it is available in several scaled versions for varying hold strength. Far East suppliers now have iterations of their own, in case your project might be on its way to overseas manufacturing.
