You missed my point. "Manufacturers" have responsibility, but its
merely financial. I was told a long time ago that in any safety
critical area, there must be "one ass to kick." In other words, a
single, real, physical human being who is responsible for something. I
think its one of the prime failings of our society that corporations
have taken the place of people in bearing "responsibility."
Corporations can't go to jail. When there's a defect in an auto that
causes dozens of deaths, there isn't an engineer, or CxO, who loses his
license to practice. There's a fine and a recall, but there's no
personal accountability. |
The danger isn't that we know about these things, it's that they may
invalidate all the analysis and building code standards we design to,
and the marketers play up the "wow" factor, ignoring the practical
implications. I know we're not supposed to have to account for user
errors, but experience shows that we usually end up involved anyway.

At the same time I do not
agree fully with Jordan that the manufacturers have no responsibility
for the strength of their connectors. If a manufacturer is going
to state that his device can support 200 pounds (s)he had better be
very sure that it actually can support 200 pounds.
On the other hand, if you
actually see someone adding excessive loading to a floor joist
regardless of the type of fasteners they are using you probably would
be smart to c.y.a. and tell them so in writing.

Lumb-R-Grip Hanger Hooks
I like to watch the DIY Network on DirectTV, but
one of the commercials I saw scared the hell out me. The commercial was
for a product called "Lumb-R-Grip" Hanger Hooks. If you view this in
HTML or RTF format then you should be able to see the image that I
attached. If not it is probably an attachment to this message and I
would advise you to look at it.
Take a look at the website for asseenontvnetwork.com at the following
In the ad shown on TV the hooks are advertised as holding up to
200-pounds and the above URL gives a good idea of how it can be used in
a basement. The TV ad hangs 20 one-gallon cans of paint from one hook
suggesting that you can use as many hooks as you need to hang
everything currently on the floor from the bottom of a floor joist,
garage ceiling joist or the bottom chord of an exposed truss or in a
shed with exposed rafters. Nowhere do the advertisements for this
product warn the user against overloading structural members. The web
site ad happens to show a duffel bag hung from a hook, but does not
suggest limiting what is within the duffel bag or how many bags should
be hung or where they should not be gathered.
I believe many of us often see areas in garages above the rafter ties
or above the lower chord of a roof truss that the owner converts to
storage. The resulting damage is costly to repair and products such as
this may contribute to structural failures without some warning by the
The product is sold at Home Depot, Ace Hardware, through Amazon.com and
many other sources.
I've left a review warning potential buyers of the product that they
should be used responsibly. I would like your opinions as well. Should
we, as a professional community, issue warnings on products that if
misused can create a structural failure?
It would seem to me that anyone who can come up with the idea would
understand the ramifications and risks in using the product.
Your opinions would be appreciated,
