Part No. 2162. Fits 7" Steel, 8" Steel, & 8" Resin frames. This looks similar to 2173 but is for 5/8 of an inch rails. This can replace part 2173, but you will need to replace your rails also. It is made out of steel. It measures 5" 5/8" wide, 3" 3/4" deep and 3/4" tall. This part has been produced for AsahiParts.com so that customers with older pools who prefer a steel joint can buy a replacement part.
