Find your Bow roller and measure the INSIDE width of the bracket it mounts to.
Keep in mind when measuring the bow roller width, the Boat latch has to fit inside the same bracket as your roller. So please measure the inside width of the bracket.
Measures 3″ to 3.5″ – You will need the 3″ model. (add spacers or washers if bracket width is larger than 3″ to create a snug fit)
***If you own a Ranger, Stratos or a boat that the bow of the boat typically drops off your existing roller during launching please refer to the Ranger/Stratos 3″ model.***
Measures 3 3/4″ to 4″ – You will need the 3 3/4″ model. (add spacers to brackets larger than 3 3/4″ to create a snug fit)
The boat latch comes in 2 different sizes. The 3” boat latch and the 3 ¾” boat latch, but what does this mean? Not all trailers and rollers are the same size, but there are two common sizes of bow roller widths 3” and 3 ¾”. We have designed and patented 2 sizes of boat latches in order to fit many more types and sizes of boats and trailers.
