Product Details
Don't let wear, tear, and corrosion stop you from enjoying your fireplace. Replace your old Blackstone fireplace grate with a new Superior Builder Fireplace Grate to safely and reliably hold seasoned wood as it burns. This grate hooks onto the grate retainers already installed in your Blackstone fireplace to hold it steady, and the black powder coat is heat-resistant and helps prevent corrosion. Superior is here to restore your Blackstone fireplace to its former glory so it can warm your winters.
Please Note: For use only with certain Superior wood-burning fireplaces.
Also Note: Always compare part numbers and information to those listed in your owner's manual.

My current grate inserts into 16-inch centers with 1/2-inch diameter. Will this Superior Builder Fireplace Grate match?
Superior Builder does not provide detailed specifications for this fireplace grate, as it is a model-specific accessory designed for Astria Blackstone 42-inch Fireplaces. To determine compatibility, please provide the model information of your fireplace unit.

Got this based on a recommendation from chimney cleaning company
We had our chimney cleaned and the company recommended to only use the fireplace grate that was designed for the firebox as it may cause issues with overheating as it wasn't designed for that specific firebox. This is why we ordered the original fireplace grate for our Superior firebox and it has honestly been better than the cast iron fireplace grate we have been using the past few years.
