STEP 1: Assemble the Main Support Bar (Parts 3 and 4)

(Note: The Stabilizers (part 8) typically are factory pre-assembled)


  • 2x Short Bolts (part 12)
  • 2x Washers (part 13)
  • 2x Nuts (part 14)

Note: Use of the locking washers (part 20) is optional

Tighten nuts and bolts with the enclosed assembly wrench

Match the head (square base) of the bolt with the square opening.

  • Note: When assembled, the two screws connecting the Main Support Bar will be off center.

STEP 2: Attach Curved Bars (1) to Horizontal Plastic Bar


  • 2x Medium Bolts (part 11)
  • 2x Washers (part 13)
  • 2x Locking Washers (part 20)
  • 2x Nuts (part 14) (Note: Some units come with bent washers instead of washers and locking washers)

Don’t over-tighten because it is just plastic.

Make sure the head (square base) of each bolt goes on the padded side of the plastic bar.

STEP 3: Connect Curved Bars to the Main Support Bar


  • 2x Long Bolts (part 12)
  • 2x Washers (part 13)
  • 2x Locking Washers (part 20)
  • 2x Nuts (part 14)

(Note: Some units come with bent washers instead of washers and locking washers)

The curved bars (1) should be nested in the plastic stabilizers (8) on the Main Support Bar (3,4).

Note: You must match the head (square base) of the Long Bolts (12) to the square openings on the Main Support Bar to ensure proper fit.

STEP 4: Slide the Vise Grips (5,6,7) on the Main Support Bar

Vise Grips (x2) are factory pre-assembled (parts 5, 6, and 7)

The Vise Grip Tightener (part 7) must be on the inside.

Note: You can place the removable padded grips (9) either inside or outside the Vice-Grips depending on your door frame width.

STEP 7: Put Thick Bolts (part 18) Through the Stabilizers (8) The Nuts with Rrubberized Threading (part 19) should be on the inside part.

  • Hand-tighten
  • No need to use a wrench to over-tighten

Note: When finished, check unit to ensure that all nuts have been properly tightened. Re-tighten if necessary (use enclosed wrench – Part 17).

How To Install

Gorilla Gym attaches and removes from most standard door frames in seconds. Once you are sure that the doorway you chose has the correct door moldings around it, you are ready to install.


Core Unit Installation

Kids Attachments

1)  Place the Safety Shim 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 simply 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. 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 into the grasp of the Safety Shim  while moving the Gorilla Gym to rest onto the top of the door frame. This allows the long horizontal bar to rest momentarily on the outside of the doorway trim with the Vice-Grips hanging in between.

3) make sure Vice-grips are open enough. Next guide the open Vice-Grips on both sides to fully slide flush against the interior door molding trim. First on one side, make sure the Vice grips align with the interior doorway trim. Tighten the Vice-Grips with the adjuster (6) until contact is tight with the interior doorway trim. Repeat with the other Vise-Grip on the other side of doorway. DO NOT OVER-TIGHTEN with the adjusters  as this might damage your interior doorway trim. After both vise-grips are secured on each side, tighten each vise grip with the bar tightener to secure their position on the long horizontal bar.

CHECK: Hold and move around the Gorilla Gym for any evidence of loose movement and to make sure the unit is securely installed into the door frame. If it is loose, recheck your steps and make sure Vise-grips are correctly aligned and tighten with the adjustor and bar tightener.
There, you are done! Typically, it takes seconds to install Gorilla Gym .
