Installing the rack was straightforward and as described in the clearly written instructions. As others have pointed out, the actual width is 33", which turned out to be perfect for my application. The quality of all the pieces appears to be excellent. Using 6 screws to attach the rack to studs, or, as in my case, structural plywood, made the entire assembly extremely stable. The wood screws provided were fine for mounting the rack over a thick sheet of wallboard, and then securing it into framing studs. Since my working surface was thick plywood, I needed wood screws with thread right up to the head - a minor inconvenience.
One design note: the dual heavy-duty hook attachments with a thin - but plenty thick enough - metal base, rattled somewhat which was a little surprising. The cams, with their thicker plastic base don't rattle at all when you slide them along the rack or when reattaching an implement. After working with each attachment type, they are both very strong - attaching a small piece of dense foam rubber behind the dual hooks eliminates the rattle.
If I could ask for one more thing from OXO - a 3rd "cam style" broom-handle holder would have been nice.
So, how useful was this top-drawer organizational aid? Truthfully, I had no idea how much I needed it. The brooms, tools and other implements laying about in the garage corner were reaching critical mass - someone (probably me) was going to get hurt. Earlier, I typically dismissed marketing department images depicting a "Before.." mangled tool mound, followed by an unrealistically dense "After.." arrangement of the same items, squeezed onto a unit. Well, I started out with a pile of things from three distinct areas around my storage corner, and it all ended up hanging within the vertical footprint of the rack. I usually hate it when marketing is right - but not this time.
I was able to hang these items on the unit (images uploaded to the product page):
Cement trowel, wedged (but easily removed) behind rack's top rim and plywood wall
Short garden clippers, hung on long finishing nail within rack hole
Shovel held in place with S-hook friction clamp on wall, but clears thin rack
Cam #1: broom - fine bristle broom - brush at top
Garden trimming shears, hung on long finishing nail within rack hole
Cam #2: broom - thick bristle broom - brush at bottom
Dual hook #1: 2 compact umbrellas, 1 full-size umbrella
Between dual hook #1 and #2: squeeze-sponge head and mechanism, hand sponge on top
Dual hook #3: squeeze-sponge handle and mechanism, small kitchen broom, large sweep broom
Could I have done all this without the OXO rack? Sure, especially now that I know how everything *should* go. But, moving the hooks and cams around in various positions ..repeatedly.. enabled me to verify easy removal and reattachment of each item, achieving what I felt was an optimal arrangement. Perfect for the obsessive/compulsive in me. Conversely, repeatedly drilling holes into a mounting surface, and using standard hooks and friction clamps is possible, but, did I manage to undertake that task in the last few years? Uh-huh.. The convenience offered by the rack is of considerable value, not to mention the additional stability of any long-handled tool held in the well-designed cam units. Additionally, of course, when an item is replaced, or excluded, or a new one is added, shifting everything around can be done with minimal effort.
The versatility of the OXO rack was especially evident in 1.) its ability to be reconfigured easily, 2.) the abundance of the pre-drilled "mounting" holes, which allowed for a long finishing nail, or a medium-size threaded hook, to be added at unused areas of the rack to mount smaller tools, improving storage density, and 3.) the rack itself being thin enough to allow an S-hook friction clamp to be used below the rack, as I did for my shovel (<-- if OXO would have included a 3rd cam, this would have been moot). Just remember that any nails or screws will be only as secure as the material they are hammered or screwed into - think chalky sheet rock - since they don't leverage the rack's stability.
It's worth pointing out that the OXO sprung cam clamps are far more secure than the standard S-hook friction variety. They are especially good at holding the broom perfectly vertical, even if the heavier brush end is topmost. The dual, thick, rubber coated hooks stick out fairly far (6-1/4"), but I had just enough clearance for them to be mounted, since a door opened right up against the rack's tools. You can stack 3 cleaning implements on one dual hook - very convenient.
If you have the money to spring for a $50 garage storage rack, this one is definitely worth it. Well done, OXO.
