Comes with push rivets! Reported to be a replacement seat pad for Manatee 9.5 kayaks, made circa 2012, outfitted with this style of pad. Assumed to be a match to the LL Bean Manatee Tandem, circa 2011.
Seat pad is approximately 17 inches wide by 17 inches long. Comes with 5 push rivets. Push rivet holes are spaced 9 3/8 inches on center for the back pair, and 12 inches OC for the front outside pair, with one center front.
It is unknown at this time, but this seat pad may be an option for the discontinued Perception Seat Pad (part number 17040112) common on many Perception kayaks, including the Swifty, America and Carolina models. Expect the push rivets will not line up perfectly. Drill new 1/4 inch holes, carefully, as needed.
Might be used as a Perception Zone Seating component on other kayaks as well. PerZone
