This Drotto Boat Latch 3″ small model w/ roller is specifically for Ranger and Stratos. Ranger and Stratos trailers come with a 3″ roller or stop and this model is specifically designed for only Ranger or Stratos boat and trailer setups. If you have an aftermarket trailer please make sure the inside width of your roller bracket measures between 3″ – 3 3/8″. The Drotto Ranger model replaces a roller that measures between 3″ and 3 3/8″ wide. The best way is to measure the inside width of the actual bracket the roller mounts inside.
Drotto Boat Latch for Ranger / Stratos Specs
installation of the Drotto Boat Latch 3″ model w roller is fairly simple. We suggest you back your boat and trailer into the water for installation. Back in until the boat starts to float. Once your boat is floating you can let out a little slack from the strap while keeping the safety chain attached. Push the boat back into the water roughly 8 inches to give yourself room to work. Remove the front roller or rubber V on your trailer. Once removed place the Drotto in its place and place the bolt through one of the 2 mounting holes. (typically the hole closest to the jaws is best). After the bolt is installed tip the Drotto to an angle that very closely matches the angle of the boat. Snug the bolt up just enough so that it is not flopping around. Now using your crank the boat in until you hear the latch click, Now snug up the mounting bolt. This should be snug enough that the Drotto boat latch does not flop around, but you also do not want it real tight. It is best that it can move. Now that the Drotto Boat latch is secure you can install the release arm. Slide the thick spacer onto the side of the shaft you want the release arm to be on. Next slide the release arm on then install the coder pin to keep the Drotto handle secure. You are all set.
