SeaDek Fishing Ruler 36in by Castaway Customs Southern Atlantic Coast | 3M Adhesive Backing

SeaDek Fishing Ruler for Boats, Coolers and Kayaks

Take the guesswork out of measuring your catch with our SeaDek foam ruler. Specifically designed for marine use, it adheres securely to any part of your boat, kayak, or cooler so you can measure a fish fresh out of the water without fumbling for a tape measure. The moody mocha and black brushed surface provides both traction and a stylish, low-profile look as you reel in a new record or capture a quick photo for social media.

With a brushed texture that enhances grip, the ruler helps keep slippery fish from slipping away while you line up the measurement. It is 6 mm thick and reads up to 36 inches, while the overall footprint sits around 39 inches by 4.5 inches, making it versatile enough for most deck layouts. The SeaDek foam features closed-cell technology to resist water absorption, helping the ruler stay functional in spray, rain, or splashes, day after day.
