Description Fits Scotty, Cannon and Seahorse Troll-Master downriggers. This is our clamp on Downrigger mount that makes your downrigger portable and installable on boat gunwale edges that are up to 4″ inches wide with scuff/jaw guards installed and 4.5″ with the scuff guards removed. The 4″ clamps are unique in the market as being the widest clamp-on option available. This means you have a wider range of boats you can potentially install your downrigger on. This mount includes our Dual-Jaw Clamps (your choice of size: 2.5″ or 4″) to make it rock solid when clamping on to your gunwale edges of your boat. The Dual Clamp also helps to correct pitch/tilt issues in order to keep your downriggers in a steady horizontal position. If your boat has a major draft angle on the sides of you boat you may also want to pick up a pair of these 15° offset jaw guards – at this link: https://www.fishfindermounts.com/product-page/15-degree-clamp-offset
