That's a good idea. My biggest concern would be whether you could maintain adequate structural integrity. Obviously hardware cloth is pretty flexible. Bending it into a U-channel will certainly help. But it's yet to be seen whether that would be enough to avoid having to put supports closer than 3 feet apart. Worth a try. A minor concern is that you'd likely end up with sharp edges with this approach. (Same problem with a thicker wire grids, but less problematic with fewer exposed cut wire ends.) This perhaps can be adequately addressed by using the plastic trim strips that fit onto the edge of panel board (1/8 ~ 1/4" u-shaped plastic channel). I would choose a grid spacing larger than 1/2". The coarser stuff made for fencing might do the job. And you'd still likely need a brake to make even bends, but with the thinner wire you could get by with a makeshift brake made from wood.

Excellent point. > Home Depot has Closet Maid wire shelves that might work for the > bending-your-own route: Yes, but I think they are more expensive (per square foot) than the ones I referenced. (The circuitous way I ran across the commercial wire cable trays is that I was looking for raw wire grid stock to use as decking in some shelving I recently setup. I bought the industrial shelving components at Lowes on clearance (they're discontinuing the product line in the retail stores) where most of the parts were near "scrap metal" prices. The wire decking was marked down to $2 per 30" x 24" panel, and I bought all they had, which ran short for what I needed. Special order they charge $7 each and take a month to be delivered. So I looked at the Closet Maid products (at Lowes) as an option. And shelf decking at Global Industrial. In the end, I couldn't find anything that I could get faster/cheaper, and instead will just make use of some plywood I already have.) The closet shelving - even the coarse stuff - has a more dense wiring spacing than the display wall grid material I referenced, which could make bending challenging. > They're vinyl-wrapped, and I suspect the coating could withstand a > gentle bending. :-) True. And they'd probably look better than any of these other options. (The display wall grids I referenced come in white or black finish. Not sure if that's paint, powder coating, or vinyl.)

The minimum width of these shelves is 12", so unless you are wiring the trunk raceway to a data center, you probably don't need something that big. If you could get them 3" to 6" wide, they'd be perfect. I see they have an offset rod spaced 3" or so in from the outer edge, so if you could find an efficient way of trimming off the other side (a big enough shear) it would maintain structural integrity. You could mount the cut edge up against the wall and have a pretty neat solution. But too big doesn't stop you from using them, and applying them without cutting or bending is obviously the least effort. One could envision a computer room in which you might run a grid pattern of these below the ceiling and just make use of some wire ties to keep the cables from sliding around on the 12" wide shelves. Thanks for the ideas. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
