These are actually designed for laboratory freezer shelves, cryogenic samples (for liquid nitrogen dewars or freezers). Stainless Steel
These also happen to be excellent sizes for holding CDs and DVDs. See pictures for fit.
The long flat boxes are similar to safety deposit boxes and are excellent storage lockers for things like jewelry, collector coins, gold, silver, platinum bullion, ammo boxes, etc. The twist latches are heavy duty and like what you see on Anvil Cases. Grid slots are removable.
Measurements are as follows:
Wide rack (DVD shelf) - 22" x 9-3/8" x 5-3/8" deep
Long rack (CD shelf) - 26-1/2" x 9-1/2" x 5" deep
"Safety Deposit" cryogenic sample boxes - 21" long x 6" wide x 2" depth
Located in Gig Harbor by Costco, but willing to meet in Tacoma if I'm out doing errands.
