This is the left rear leg of the KingChii Damniss HWPG 456A (only) Pellet Grill.

If you are unsure which model 456 pellet grill you have, there is a reference point. Model 456A has a grease cup that mounts on two pegs on the side of the grill just under the grease drain. Whereas, the 456B has a grease bucket hanging from a hook mounted just under the grease drain.
