Bulina Dual Lock SJ3550 1" X 8.2 Ft Reusable Fastener Heavy Duty Adhesive Hook Lock Sticky Black Mounting Tape Black Color for Indoor and Outdoor(3550A)

Very strong, hold wells and can take a beating

This stuff works very well. Much better than velcro

Pretty sure you could attach anything to anything with this stuff. I’ve attached some heavy guitar pedals to a varnished plywood base without issue. I would definitely recommend over other hook-and-loop fasteners when weight and reliability is an issue.

It's strong enough to keep my light curtains hanged on the wall or the ceiling, I'm surprised how strong they are. It can tears out the paint if you try to remove it. Before installing anything male sure to choose the good and the right place, cause when you remove it, it can probably remove the paint on tje wall. I prefer usong these than making hols on the wall. If you remove them carefully, you can be safe, but overall all good quality, strong glue, easy to use, but a little bit expensive.

For the first time, my pedals stay exactly where I put them. I can hold my board upside down and shake it — nothing moves. Very easy to install and maintain. Glad I bought it. With the price.
