I wish I had a good rack story to tell, but i don't. Fact is, over the years I have spent all kinds of money on every type rack you can imagine. I have never had one break. I have never had one damage a trimmer. I have never even had anything stolen off of one. Want to know why? They are so hard to use and such a pain that my guys just put the trimmers in the back of the truck and never use them. Since I run enclosed trailers, they do store them on the racks at night, but first thing in the morning they are in the bed of the truck. It appears your system may be a better idea that will make them want to use the racks. Thanks and good luck with the product.
