Manufacturers of garage rack focus on rack capacity in their advertising, but focus on the garage structure in their installation instructions?
For decades, homeowners have been taught to ask:
"How much weight can the rack hold?"
400 lbs? 600 lbs? Or even 800 lbs?
But while reading the installation instructions from one of the largest ceiling-mounted storage rack manufacturers in America, I found something interesting.
They don't say your garage ceiling can support 400 lbs.
They don't say your garage ceiling can support 600 lbs.
They don't say your garage ceiling can support 800 lbs.
Instead, they say:
"The ceiling must be capable of supporting the combined weight of the garage rack and your stuff."
Read that again.
The marketing talks about rack strength.
The installation instructions talk about ceiling strength.
Those are two completely different concerns.
A ceiling-mounted rack can be rated for 600 lbs, but that does not automatically mean your ceiling above you was designed to support an additional 600 lbs of suspended storage.
The instructions go even further, stating that if the ceiling cannot support the load, the structure must be reinforced.
That raises this question almost nobody asks:
If the rack rating is the most important number, why does the manufacturer spend so much time talking about the ceiling in the manual?
Because the real question isn't:
"How much weight can the rack hold?"
The real question is:
"Where does the weight go?"
The screenshot below came directly from the manufacturer's installation instructions.
