I tend to be some what of a DIYer. I first picked this store because all most of the supports looked pretty stout and my wife fell in love with the design. When they arrived I was very pleased with the how well built and sturdy the supports were built. At first i was slightly concerned with how small the bolt holes were, i even considered drilling two more to carry the massive weight of the countertop i was installing. Time was of the essence so i didnt take them down to the shop, but I did use some long bolts with washers and nuts. During the installation of the countertop the installers rested the full weight of my 700 lbs countertop on just the 4 supports I installed for a short while and they didnt move one bit out of level, even they were throughly impressed. When I build out my bar room bar top I will definitely purchase from this company and would suggest it to anyone else looking for beautifully designed well build supports.
