This is a universal fridge slide, designed for the Dobinsons 4x4 40 and 50 Liter fridges, but it will also suit almost all other brands of 40, 42, 45, and 50 Liter fridges and coolers, as they all use a similar sized footprint (measure before ordering). May be ideal to use on these popular brand fridges: ARB, Engel, Dometic, Smittybilt, Truckfridge, Edgestar, Yeti, Rtic, Snomaster, Coleman. Measure before ordering. This is an all-steel design with quality roller bearings for rattle-free use. It comes with 4 fridge tie down straps, and is a great compliment to your fridge/freezer, especially when access is difficult in the back of your Jeep, Truck, or SUV. This simple slide adds just under 2" of height, but allows the fridge to open easier once the slide has been extended. For vehicles with a low ceiling, this allows the fridge to slide out to an open area and be able to fully open the lid to remove or install the internal fridge basket, or simply to access everything inside the fridge. In addition to those features, this slide when properly installed and bolted down to your vehicle floor will ensure that your fridge will not move during off road adventures, as a fridge fully loaded could easily be over 75LBS and could be extremely dangerous if not secured properly.
