I had a small bottle chiller before i bought a blast chiller.
I cut a stainless steel plate to fit the top of the chiller. Then made two straps, 2 x a wide T piece bent through 90 degrees just below the top of the T piece. I drilled out the top plate and top of the hanging T pieces and pop-riveted them together. This meant that I had two 1" wide straps hanging down the middle of the sides of the chiller.
As I fitted a bar (stainless tube) between the hangers, I carefully measured how far down I would need to drill to allow S hooks to fit over the top of the tube but missing the top of the chiller. I then marked and drilled out the hanging straps, then marked the side of the chiller and used a hole cutter to drill through the chiller sides.
The stainless tube was cut to fit between the hanging straps and a piece of all thread 2" longer was pushed through the middle of the tube, this was M8 and washers and nylock nuts were fitted on the outside and tightened up. I sealed round the edge of the tube with silicone sealer. It held a roe buck easily. This had the benefit of not interfereing with the chiller unit at the top and back of my cabinet.
If your cabinet is one of the big ones then you might fit a stainless frame inside, but make sure it can take apart otherwise, if you are anything like me, blood will get behind it and stink.
