Gorilla Gym attaches and removes from most standard door frames in seconds but make sure
your door frame and the moldings around it are safe, secure, and solid. If you see any breaks or
weakness in the frame or surrounding moldings, your Gorilla Gym should not be used as serious
injury may result. Once you are sure that the doorway you chose has the correct door moldings
around it, you are ready to install.
1) Place the ‘Safety Shim’ (16) with the sharp
end behind the middle door frame molding on
the same side as the door hinge. Make sure it
is inserted and secure behind the molding.
Note: In some occasions, the space between
the wall and the door trim may be painted over
so you won’t be able to slide in the safety
shim. In this case, you can press down the
safety shim and the sharp tip will penetrate the
paint or you can choose to install Gorilla Gym
without the safety shim. The Safety Shim helps
keep the Gorilla Gym in place while you
secure the Vice-Grips on the sides of the
doorway moldings. (See figure A).If installed
correctly, Gorilla Gym is safe to use without
the safety shim with most attachments. You
must install the safety shim when using the
Speed Bag.
2) Place the bottom of the Gorilla Gym’s
plastic bar (2) into the grasp of the Safety
Shim while moving the Gorilla Gym to rest
onto the top of the door frame. (See fig. B).
This allows the long horizontal bar (3 + 4) to
rest momentarily on the outside of the doorway
trim with the Vice-Grips (5) hanging in
between.
Note: The horizontal bar must be installed on
the opposite side of the door (see figure C).
