To short for install with 16" on center studs
"Heavy metal, nice finish, sturdy. . . but poorly designed. . . maybe it was designed in China or someplace not familiar with US building codes for 16" on center studs. It needs to be at least 49 1/2 " long to mount between two studs with holes 16" on center. My daughter asked me to come over to install the unit in her barn which has stud walls and battens covering the 4x8 sheathing joints. But the units are about 46 1/2 inches long, You cannot attach them into the studs. None of the other mounting methods work when the walls are effectively 6 inches thick (3 1/2 stud, 1 1/2 stall board, 1/2 sheathing, 3/4 batten). I had to add a horizontal batten between the two vertical ones as a shim, screw a 2x6 into the two studs and screw the rack into the 2x6, a pain and adds more torque to the unit. You CAN do better then this design."
