Review on Get Fit With ONETWOFIT Wall Mounted Pull Up Bar - Multifunctional Strength Training Equipment For Indoor Home Gym Workouts by Donald Blanco

I installed on 2 pieces of 1/2" plywood 31"x16" and 31"x14" spray painted black. The frame units were mounted to the plywood using 6x 1/4 in -20 x 1 in machine screws (home depot pn 530-681) per frame piece, total of 24 screws. I scaveneged the washers from the m8x80 expansion screws that were included. The machine screws were preinstalled from the back prior to mounting the plywood pieces to the wall. The plywood mounts were anchored to studs using 10x 2.5 inch wood screws I had lying around.A previous reviewer complained about the dip and ab station wobbling and solved this with 5/8" washers. The problem is more simply solved by installing the included plum blossom screws from the *inside* of the frame (the instructions and online photos direct you to install from the *outside* of the frame). Installing in this manner eliminates the wobble and further allows quicker removal of the upper screws to fold down or remove the dip and ab station arms.
