I am fishing for some help please , I am building a skid house and need your advise regarding the runners . I am using 4 x6 x 12 foot fir for the skids but would like to put a plastic or nylon runner underneath but am not sure what to use or where to get it from . I would think that it should be around 1/2 inch thick as the fasteners would need to be countersunk . Any suggestions would be appreciated
Thanks in advance
Cheers !
