I have for sale my pARTiculat Triangle that I have owned for 23 years. The rack is signed and numbered by the designer Volkmar Drubisch. The following is included with then rack:
4 x black "I" support self supports 26" W x 18" D
3 x white acrylic shelves 19" W x 18" D x 1/2" H. Shelves are gloss white on one side and matte white the other side. All side edges are gloss white.
1 x opaque shelf 23" W x 18" D x 1/2" W
25 visco elastic/aluminum isolators used between the shelf support and shelf.
The legs and shelves can be adjusted. Depending on how you configure the legs the maximum measurement of the rack will be 46" H x 35.5" D x 27.5" W while the minimum measurement of the rack will be 46" H x 26" W x 21.5" D. You can have various measurements in between as well, only the height is constant at 46".
Rated 7/10. Note that the bottom shelf support in the photos has a hex screw that is stripped so while adjusting/removing the shelf is possible, it will be more challenging than the other shelves whose hex screws are intact. No spikes included.
This is a high end rack that works extremely well. As a reference you can see what they currently sell for here: https://www.ebay.com/itm/306205940785
