I have about 8ft. 6in. clearance in my garage and had more than enough room for this rig. There are no instructions but a little common sense goes a long way. Concrete bit and a drill for the floor mount kit and a few 2X10s screwed into the wall studs then lag screw the rack to the 2X10s and your done. Took me less than and hour with a buddy to help. I did local pick up so I don't know how the freight is. I live 90mins away and they had it ready to go with no problems. Emails were answered quickly. With all that being said this rig is awesome. I weigh in at 235 lbs and I can do kipping pull ups without worry of it coming down. It is well constructed and affordable. I have purchased other equipment (bumper plates and female Crossfit Olympic bar) from Vulcan as well and they have yet to let me down. I will continue to buy from Vulcan.
