Abstract: A vibration absorption system for a rooftop mounted air handling unit is disclosed herein. The vibration absorption system includes an upper rail. The vibration absorption system also includes a lower rail. The vibration absorption system also includes at least one biasing device disposed between the upper rail and the lower rail. The vibration absorption system also includes a fastener having a head and extending through at least a first portion of the upper rail and at least a first portion of the lower rail to interconnect the upper rail and the lower rail. The vibration absorption system also includes a nut releasably engaged with the fastener. The first portion of the upper rail and the first portion of the lower rail are disposed between the nut and the head. The nut is adjustably positionable along a length of the fastener wherein adjustment of the nut along the length of the fastener varies an extent of compression of the at least one biasing device.
