Does anyone know what the pressure clips ( not sure what to call them ) are called and where I might try to look to order. Want to be able to fasten top of amp rack and have it secure, yet easy to take off with a pull of the top. I guess I would say they look like the clips you have on your speakers at home that fasten the grill cloth to the speaker. Thanks

 

I call them "male/female speaker grill clips".

 

Another option would be magnets or velcro.
