The Cradle Cover Lifter works for circular spas and spas that can't fit a regular lifter like the VX3.
Be aware that a support plate needs to be installed underneath the spa - the spa pool needs to be lifted and the bottom plate slid underneath. 2 persons can lift an empty spa pool using the edge of the acrylic while pushing the plate underneath.
Attached are the instructions for the Cradle Lifter.
