Re: Putting rubber skids on a Rogue Monster Yoke
HDPE or UHMWPE cutting boards bolted to the bottom would be great. Drill partially through them with a forstner bit to countersink the bolt head.
Another option would be to use rubber stall mat feet at each end of the yoke legs, or under the entire length. Again, forstner bit partially through to countersink the heads.
Or a cheaper option, wrap a car floor mat around the bottom legs, and secure it to the sides of the perforated tubing with the weight rack flange bolts.
