If for any reason you are missing any of the above parts from your MONSTERRAX unit, please call us at 1-866-484-4729.  Ensure all the required tools available for your installation and a clear path to work during installation.

Determine the desired location for the unit and survey the ceiling structure. Remember, you will roughly need enough ceiling space for the size of the rack you are installing.  Start by locating the ceiling joists (the horizontal studs or beam components of the ceiling structure). If your garage has finished drywall on the ceiling, use a stud finder to locate both sides of the ceiling joists.  Use a pencil to mark both sides of the ceiling joist. See FIG 1.   WARNING: This system is not intended for steel framed homes.  Do not attempt mounting to steel beams.

locating ceiling joists
drilling tap holes
The idea for mounting the ceiling brackets is to get the screws to go into the center of the ceiling joist.  Each angle of the ceiling bracket is 1 ½” so center it up within the two lines you have drawn.  Hold the bracket against the ceiling with your hand and place a mark on the ceiling inside the two end holes.  See FIG 2.  Use a 3/16” drill bit and drill a tap hole at least 2 ½” deep before insert the lag screws.  See FIG 2 and 3.

Driving lag screws
Secured ceiling bracket
Place a washer on the lag screws and drive them into the holes you drilled.  DO NOT OVER TIGHTEN.  It is possible to strip out the hole or break the screw if you over tighten.  See FIG 3 and 4.  WARNING:  For SAFETY, each lag screw needs to be driven at least 2” into the wood joists above.  Six inch ceiling brackets work for the majority of framed garages.  In some cases, you may need a longer one.  Ceiling brackets are available up to four-foot lengths by calling 1-866-484-4729.  We will be happy to send you the pieces you need to complete a proper and safe installation. 

Use a tape measure to mark the remaining positions for the other three ceiling brackets.  The diagrams below show how a 4 x 8’ unit  fits on a ceiling with joists at both 16” and 24” on-center.  For other frame sizes measure out the bracket placements in the same way.  IMPORTANT:  All ceiling brackets must face the same direction on the ceiling. 

Installation diagram
Take the vertical posts and adjust them to the desired distance from the ceiling.  Ensure the lower section of the vertical post is placed on the inside of the two post pieces.  Use two bolts with washers on both sides to secure the posts together.  Next, use a single bolt, with washers on both sides, and connect the vertical post assembly to the ceiling bracket.  Repeat this step for all four posts.  IMPORTANT: Ensure the teardrop holes are facing down.  See FIG 5, 6 and 7.

Finished Nut, Bolt and Washers
Once all vertical posts are in place, begin placing the side beams.  Start on the short ends and finish with the long sides.  IMPORTANT:  For Safety, use a helper when securing the beams.  Seat the rivets into the holes using a rubber mallet or hammer.  Continue seating the remaining beams.  WARNING:  Opposite ends may come loose when hammering beams in place.  Use a helper to ensure rivets do not come loose during the seating process. Beams can come loose and fall potentially causing damage or injury.  When all four beams are in place, conduct a final inspection.  FIG 9 shows a fully seated beam.

Connect the center support (Models: 4x8, 4x6, 3x8, 3x6, 2x8, 2x6) using the remaining flat-head bolts and wing nuts.  See FIG 11 and 12.

You are almost finished.  Take the wire decking and place it on the racking unit.  Wire decking remains in place by gravity and can slide freely side-to-side.  There will be a small space between each deck. See FIG 13.

Take one last look at all the rivets to ensure they are properly seated.  In addition, make sure all bolts and nuts are tightly secured.  Look at the ceiling bracket lag screws and ensure they haven?t backed out during the beam seating process.  You are now ready to load your storage rack.  WARNING:  Load heavy objects nearest the vertical posts and light objects nearest the center.  Read the safety label on the rack and do no overload the system.  Do not climb on or hang from the storage rack.  Routinely inspect the rack over time to ensure rivets and wire decks are seated properly.

These weight limits are based on a framed garage with a minimum of 2 x 6" (standard lumber) ceiling joists at 24" or less on-center.  For truss framed garage ceiling structures, 2 x 4" (bottom truss cord) is okay.   The racks themselves are structurally rated to double the above limits.  However, the weakest point in the entire system is the garage ceiling joists and rafter system.  If, for any reason, you suspect the integrity of your ceiling structure is in question, discontinue the installation process.

These instructions and respective weight limits do not preclude sound judgment and decision
making when installing and loading your overhead rack.  Bottom line...Be careful, use the rack wisely and enjoy your new found space!
