SW1048 is similar to SW1047 but is secured to the boat with 3M VHB tape instead of screws allowing for a sleeker look and simpler installation process . This scupper assembly is TIG welded together by Seaworthy Innovations at our Westborough, MA facility.

It has a 1.625” thru hole which is larger than the common plastic frame version which has a 1.375” thru hole. This means ours will fit over the brass drain tubes of transoms which typically have a 1.5” flare.

Frame: 316 Stainless Steel (mirror-polished)
Flapper: 316 Stainless Steel (mirror-polished)
Backplate: 316 Stainless Steel (Electropolished)
