Debris plates are often known as closure plates and they are a sheet of galvanised steel. These plates are used to seal off the opening in the chimney to prevent soot and chimney deposits from falling into the fireplace opening. If you have an older masonry chimney, then you may get sizable deposits falling down which could be messy and dangerous. These debris plates or register plates are made out of metal and they can seal off the base of the chimney.

At Flue Supplies, we supply an incredible range of chimney plates, flue adaptors, and clamps. Our flue adapters, support plates, and top clamps range in various sizes from 125mm to 150mm. If you’re looking for high-quality chimney closure plates or register plates, then look no further.
