This is the real deal - perfect for protecting a couple of standard extension cables. However, although I am currently using for a 50 amp RV cable, the inset in the underside of the cable protector is not deep enough for the diameter of the cable, so the cable protrudes below the lower flat side, increasing the chances of abrasion to the cable with every movement over the protector. I suppose you could use another cable protector upside down underneath to fully protect the cable, but this would increase the trip hazard. Another option that I have not tried might be to use 3 protectors in a pyramid style, two on either side of the main one as addition supports, but I can't imagine that arrangement holding. It would be nice to have a slightly bigger version of this cable protector ramp able to fully enclose a 50 amp cable. But for standard 25-50 foot 12 gauge extension cables, two will easily fit. Not so sure about a 10 gauge.
