These are Stratford and Aarrow’s (Arada)  newer style grate bars. They can be identified with the marking CST019 on their underside whereas the older style will have NGB1B printed on them.

If your stove currently has a set of older style grate bars we recommend you replace the whole set in one go, if the older and new style grate bars are mixed they may not riddle very smoothly

Most commonly used for Stratford Eco Boiler 12/16 HE Freestanding Stove
