A split aluminium plate used to support the liner at the top of the stack
Brilliant Product I recently installed a Pizza Oven,& had to extend the Metal flu up through a Plywood Roof. I used two combined plates & clamps top & bottom, after I had cut a hole through 2" larger than the Flu Diameter, then filled the void with Asbestos matting & Fire Cement, so as to dispense with any fire risk.

Gas Liner 100mm Clamp Plate Had a new boiler fitted and the new flu diameter was slightly smaller than the old one which created a gap in the roof top plate. Your clamp plate fitted easily on the top and filled in the small gap.
