Our Double-Sided Circular Spigot Plate is designed to securely join two sections of duct in HVAC and ventilation systems. Each plate features male IL flanged spigots on both sides, allowing both ends to fit into sockets or couplings to form strong, stable, and airtight connections. The plate provides structural support for mounting to walls, ceilings, or other surfaces, helping maintain efficient airflow while allowing easy installation and precise alignment of ductwork.
The size of the double-sided circular spigot plate is based on the diameter of the spigot:• For spigot sizes up to 250mm the plate will be spigot size + 100mm.
Example: 200mm spigot → approx. 300mm total plate diameter.
• For 300mm spigot and above,the plate will be spigot size + 150mm.
Example: 300mm spigot → approx. 450mm total plate diameter.
