Zekoo bard door hardware kit. Went a different direction with that doorway. Doors cannot be thicker than 1-3/4 or the kit won’t work. Because of the door overlap, your door width should be 6” wider than half of the opening width or the opening cannot be fully covered. Usual Track Length=Opening Width+1FT. Service Assurance? ZEKOO stands by you all the time. Please do not hesitate to contact our customer service team if you have any questions. If parts missing or broken, we will send you a replacement ASAP.
