The Scupper Pup's two crossbars allow it to fit almost any sit-on-top kayak. One set adjusts from 6”- 11”, while the other slides from 13”- 17” (middle of post to middle of post). The Scupper Pup carries up to 200 pounds and its frame is made of powder-coated aluminum with a hammertone finish. Our new Quick-Release Wheel System features quick, convenient mounting and dismounting of tires without the need for keeper pins. Featured in the August 2004 issue of Canoe & Kayak Magazine.
