Fianally broke down and bought the GridIron rack for my trailer. Gettin tired of unloading trimmer and blower from back of truck all the time. Got it installed today. Work will be easier this week Anyone else use GridIron..... Anyone know if its possible to buy those "T-Nuts" or whatever you'd call them, that they use in the tracks... I'd live to get some so I coud make some of my own add-ons to the bars.
