Hi. Sorry for the poor score. The ordering process and quick delivery were good. I ordered 6 trailer u-bolts and the online site made it easy to measure and order the correct bolts. However when they arrived, only 2 bolt fitted the brackets. When measures I found 4 of the 6 bolts measured 56mm-58mm when 50mm was ordered. Two were correct. When I rang to advise I was first told I ordered the wrong size. Later to find your man was looking at the wrong order. Then I was told I measured wrong as I measurements are done on the block frame they were fitting. This is not what your website says! Then I was told they all could be slightly out which was normal?!? 58mm from 50mm is 16% out!! that is not slight. Especially when they are over £5 each. Then I was told I was measuring the bolts wrong as he and his chairman measured them all that weekend! I'm no expert but was made to feel as though I was constantly wrong. finally I was advised that there is nothing I can do apart from squeeze the end of the bolts in to fit the brackets, This I haven't been able to try due to the weather but if works, surely the top of the bolt will still be up to 8mm wider still? Will not use this company again.
