Interior mounting plate for waterproof box

Blank internal mounting plate for boxes with 100 mm spacing that do not come with plates, such as the popular Zulkit IP65 box, size 5.9x3.9x2.8 inch. Punch or drill holes for the desired components. Machine screws can thread into the plastic directly, or use nuts to bolt components to the plate. (Tip: flip the plate if you need more room for screws with nuts.) Secure the assembly to the box using M4 machine screws and washers.
