The injected molded cap will slide over the 3x4 opening and provide you with a rectangular opening to fit your 2x3 downspout pipe. You MAY need to crimp your 2x3 downspipe a bit to make it fit. Not all downspout pipe is exaclty the same size/shape. It's easy to crimp and crimping instructions ca be found in the left navigation bar under Important Links.
