This is a 40x4 character LCD enclosure, created to protect the LCD from outside conductive particles and provide housing/mounting capability

This is a simple screw together (M3 screws directly threaded into the plastic) LCD enclosure for a 40x4 character module. This particular one is a NewHaven Displate - NHD-0440AZ part number, but the dimensions are standard and should fit most 40x4 character displays.
