I like the boards, but the installers did not. I took them to a 4x4 specialist with stores nationwide who said the fasteners, which resembled rivets were wholly inadequate to hold the weight of the boards plus whoever may stand on them. They instead drilled larger holes and used heavy duty bolts. They only charged me the $150 they quoted me to do it, but it took them several hours. Overall, they were shocked that they came with such weak hardware, but liked how they ultimately looked and fit. I would agree.
