I had a single handle that wasn't doing the job on my enclosure (made out of 3030 extrusion) and the acrylic sheet door/panel was starting to bend at the top and bottom. These are now mounted at both the top and bottom about 10 mm from the corner.
The acrylic door is 3/16" inches thick.
Uses 4 - 6mmx3mm magnets.
The catch mounts to 3030 extrusion.
The latch is held in place with a small 3mm screw.
The author marked this model as their own original creation.
