If you would like to build sturdy garage overhead mightyshelves as described in my earlier post here, but don’t have attic space above your garage, one of several alternative hardware support methods is required. The original design for these shelves uses threaded rod with washers and nuts. You run a piece of threaded rod through the shelving and up into the attic space where it is secured to a block with washers and nuts that is fastened to the top of the bottom chord of the trusses. But you can only use this method when you have accessible attic space above. When you don’t, (when your house has living space above your garage for example), you’ll need to use an alternative hardware support method.
A couple of hardware variations include screwing eye lags up into the framing in your garage ceiling, or fastening a piece of perforated metal angle (similar to what is commonly used for supporting garage overhead door tracks and motors) to the framing in your ceiling with some 3″ Spax lag screws. Then you can attach chain, or wire rope, or perforated metal straps, etc. to the eye lags or metal angle to support your shelves below.
I recently came up with a hardware method that still allows you to use threaded rod, with a slight variation at the top, that works in cases where you don’t have accessible attic space above. You use a coupling nut to connect the top of the threaded rod to an eye bolt. Then you use a quick link to connect this eye-bolt to either an eye-lag screw or metal angle that is screwed into the framing in the garage ceiling. Here’s some pictures of this garage overhead mightyshelves hardware variation:
