Absolutely one of the worst purchases I have ever made. To put it in perspective, I ended up buying an epoxy resin to complete assembly.  The metal pieces used to construct door were so poorly made that they snapped like twigs. Some weren't even milled properly so they were absolutely useless. And guess what those pieces were for, u got it.for tightening the wood that surrounded the glass that made the door functional. 
Do not waste ur time or money. Spend-a- dolla (u know u got it) and get something worthwhile...huh sliding barndoor my a**
