These brackets are a replacement for standard, permanent L brackets commonly used to assemble enclosures.  They can be used to create enclosures that can quickly be assembled and torn down without the use of any tools.

Two different designs are included.  Both designs provide mating alignment provisions as well as accommodations for common magnet sizes.

There is a structural pair that hold 32mm x 6mm magnets and have provisions for fastener (rather than tape / glue) mounting.  These large magnets can apply significant holding force.

The second pair holds 9mm x 3mm magnets and are ideal for removable panels.  The magnets hold firmly, but not with so much force that removal of the panel is difficult.
