You are buying 4 PCS of REGULAR CHROME PLATED STAINLESS 7" WIDE STACK BRACKET FOR THE 3 PIECE MONSTER STACK APPLICATIONS. This type of stack bracket covers the seam that is formed when two pieces of 7" tubes are slid into each other for a clean straight stack look.Nowadays, straight stack looks are actually 3 pieces of components slid into each other,  covered by the bracket on the seams. This makes for a practical approach on problems created by the one long piece straight stack on chroming, shipping, and warehousing.
