Want a frustrating way to spend an entire weekend? I didn't but that's what I got anyway. Instructions are practically non-existent. This provided me with endless opportunities to assemble, disassemble, and re-assemble multiple times. Pre-drilled holes? Only for the decorative pieces on the front of the doors. All other pieces had to be drilled. Oh, and if you don't have a 25/64 drill bit as required, don't worry because that hole will be too big anyway. Once you finally get the doors built the real fun begins. Yep, that's right, you get to hang the hardware. But wait, the decorative boards have a slight overhang. No big deal as long as you had the overhang on the outside of the doors. I know I didn't, so when I went to put on the hinges, I got the opportunity to re-align all the decorative boards. Now that the first fun is over. Be sure to precisely follow the instructions, get your doors hung, realize the doors are dragging the ground and that the instructions are about 1 inch off. Now, take them back down, remove the hanging bar from the wall, and do it all over again. What fun! If you like, you can scream expletives the entire day. (Not recommended if children are present.) Do the doors look nice? Sure. Do they operate reasonably well? Again, finally yes after hours of trial and error. Was this WAY WAY WAY too difficult? Again, 100% yes. And, keep in mind, I have just about every tool you could possibly have and 40+ years of doing projects like this. If you do NOT have a heavy duty drill, multiple differently sized drill bits, a helper who can assist with every task, and more patience then you could possibly imagine, then you might want to stay away from this little 'project'.
