These things are GARBAGE. Your Quality control is worthless. I can't believe your engineering department would let this go this way. This pallet frame needs to go through testing before you release this to your customers to do this testing for you. You must know from other customers who use these products that there is something wrong with the durability. There are no welds worth a dam, of what welds there are. There are no welds where you need them the most. Also, the lower channel is only 1/4 inch thick. My brother-in-law's subcompact has thicker steel in the same spot, and the entire frame is completely welded, not a spot here and there. I called about the warranty and the man who took my email did not ask what specifically he wanted, over and over again. I am asking him to be more clear about what he is looking for. He was not very helpful. I was wondering if I would get a replacement. Also, I asked about an upgrade and paying for the extra cost. He said he couldn't do that. The replacement unit would have more welds. I got the replacement unit, looked at it, and it was bent up and it had no more welds on it than the original frame. I wanted an American Made component, and tend to look for these over anything else first. It is just a shame. I can't recommend your product to anyone. I don't ever think I will deal with your company again. Your stuff is total junk. It took a couple of days to respond to my first inquiry about a replacement. beyond that, it was either a full day, to within an hour. Then had the gal to rate in well.... really? what a jerk. Now, that I have a replacement unit, it needs to be welded up before I can use it, as it is not reliable, and will likely break again. I am not sure Titan would return this unit for a real, welded unit. I am not sure if I did and paid for the Heavy Duty version, it would be worth a darn either. So, since you asked about this product and the service, I could not delay telling you what I thought, and what I need to do to get a Pallet Frame put together that will actually work. I hope your quality control people take note of this and put into action a plan to improve your quality. If you don't, word of mouth will destroy your fine name. I for one, will not be spreading the word about how good your products are.
