This solderless breadboard features three binding posts, two power buses, and a black metal plate backing. It works with a wide variety of wire gauges (29-20 AWG). Note however that the power rails are unbroken on both sides, which is a bit different than most breadboards.
The board itself measures 165 × 56 × 8.5 mm.
The metal plate it rests on measures 183 × 95 × 1.5 mm.
