Hosco Aluminium ground shield plate for Stratocaster - Small '54-'59 style
This is Hosco's aluminium control plate shield that is designed to fit underneath most American or Mexican-made Fender Stratocaster pickguards. It's based on the ones seen on Stratocasters produced between 1954-1959. The beauty of this particular shield is that it's a universal fit so to speak too, so it should fit most Stratocaster models.
To install this shielding plate, you simply need to lay it over the back of your pickguard and then re-attach your pots, switch and that will be enough to hold it in place - no adhesive required.
