A couple of ideas that we ended up using ;
Stern Siderails - We had them powdercoated black, along with the door, legs and lockdown bar. I had to slightly modify the cabinet to accommodate the siderails. Very pleased with the result. The screws I used are factory Torx screws which are difficult and expensive to source.
I used the Mantis cabinet protectors ( concealed ) - and they installed easy and are thicker than other metal protectors. Not a hope in hell for the legs to get near the cabinet.
Here is a more detailed photo of the clearance, and I also used red leg bolt washers with original repro style Data East Legbolts.
