This Avantco 17817659LEG4 adjustable seismic leg kit works with select Avantco refrigeration units to ensure they're kept firmly in place. This adjustable seismic leg is the perfect solution for raising your equipment between 4 1/2" to 7" while keeping it firmly attached to the floor and in place. Including 4 seismic legs, this kit provides the necessary space for cleaning and performing maintenance on your Avantco equipment. When the equipment rests directly on the ground, it is difficult to clean underneath or behind it. With this leg kit, you get the extra few inches you need to make sure your equipment stays in top condition and the surrounding area stays clean. It is adjustable so that you can make sure your equipment is level on uneven floors.
