Clamps will be stamped with LavaLock lettering Beware of copies! NOTE: This item includes the plunger hardware, nuts and brackets but cannot include mounting screws. This is because they can be mounting via screws, bolts or welding, and the thickness and location of the clamps determines the bolt/screw size. Thick wall applications require long bolts or screws and thin wall require smaller hardware. If you are looking for a Highland Clamp, check out LavaLock LL-12050, as this clamp is not ideal for that smoker
