Spigot plate adaptors allow for the creation of a spigot connection onto a normal flat surface whether it is horizonal, verticle or angled. These adaptors can be secured by screw, rivet or nut and bolts onto any flat surface. They have a flat square backing with a round spigot for connection. Metal wall plate flanges are used to neatly vent air from one room to another or to vent hot air from the inside to to the outside
very well made with a snug fit, these are perfect for hydroponic, catering and any other ventilation requirements.
