Bests & Worsts Reviews from Amazon

First, the good: well constructed, solid aluminum pieces. Looks good. The bad: bought the 1.75" clamps to fit the 1.75" diameter tubing on my bull bar. Using the parts supplied, even with the screw down as tight as it can possibly go, there was still a significant gap (visible light between the inner part of the clamp and the tubing), and it would just spin on the bar freely. The images for this product here on Amazon show that if there's not enough clamping, then to cut an aluminium soda can into a strip and use that as a shim. After driving to the closest convenience store to buy a $2 Coke just for this purpose, it still didn't work. I should have known better. The only thing I had around the house to try and fill the gap was some double-sided foam tape. Tried that and it just compressed too much and made a sticky mess. After giving up and nearly returning the clamps, I slept on it and the next morning came up with an idea: bicycle inner tube cut into strips. Went to Walmart and bought a $5 20" bicycle tube. Cut it into the size strip I needed, wrapped that FIRST around the tube and then used the clear silicone gasket. That did the trick! Just the right thickness and most importantly, provides so much grip that with putting my weight on the clamp it will NOT rotate! Save yourself a headache of having to engineer this to make it work and try my trick. Be sure to thank me with a "helpful" vote!
