The Flat Cap is the SmokeWare alternative for customers that like using the OEM porcelain cap to snuff-out the firebox. Great for older BGE/KJ’s that may have lower vents that leak air or failing grill gaskets. Includes a Nomex® bottom gasket for super tight seal. Note: Our vented chimney cap is designed to extinguish the coals when fully closed but purists may prefer using our Flat Cap. Ask for it "without felt" to use as a burger smash or steak weight.

This Smokeware Flat Cap is made of stainless steel and will become hot when used during grill shut-down. *Read Why You Would Want To Purchase A Flat Cap
