This kit is specifically designed to fit the Engle/ARB/ Norcold style of fridge and works on all sizes. The 60 and 80qt sizes already hinge in this direction so the main focus is the 45 (pictured) and the 35. Customers have used the hinges to modify many types of fridges though since the fit is fairly universal.
The supplied hinge is an adjustable tension hinge that is capable of holding the lid of a 32/45qt cooler open, the larger sizes are pushing it for tension but the hinge will still work just fine. So, keep in mind that on the very large fridges the friction hinges may not hold the lid in position until it is fully upright due to the extra weight. Also keep in mind that if you crank down on the friction screw to make it work you are putting excess stress on the mounting screws, they are only screwed into sheet metal so use common sense, don’t rip them out. (If you do you can replace them with nutserts). In general; abuse will stress the mount points, don’t crank up the tension, don’t fop the lid open, etc.
