Move raised appliances with ease using the Airsled Spacer Kit. Built for dual air beam systems, the kit closes the gaps for appliances and other loads on sitting legs such as oven ranges and refrigerators. These strong, durable spacers bridge the gap between the top of the air beam and the bottom of the load, letting you move any appliance with your Airsled movement system. The kit includes spacer blocks that can be set at heights of 2 inches, 2.5 inches, 3 inches, and 3.5 inches, lifting up appliance legs so they can slide on the air beam. For use, determine which settings get the block closest to the appliance's base (final gap should be 0.5 inches or less) and position the blocks under weight-bearing contact points. Do not place below trim or other bendable, non load-bearing points. Tall, top-heavy items such as refrigerators require extra caution when moving using an Airsled System. Avoid injury by pushing or pulling loads slowly from the center to prevent tilting. Do not use ramps or stairs. Make moving large appliances with high legs a breeze with the Airsled Adjustable Spacer System.
