Your review: It took some time to find firm wire shelves in this dimension. Most home supply stores have items much smaller.
The plastic home helves I used previously warped to a point they were tilting.
These larger units seem to be quite sturdy, as sturdy as the smaller ones I already owne.
I have not put any articles on them yet, but i expect them to work quite well.
The only problem i had was adjusting the height after making a missmeasurement. The shelf was very difficult to dislodge, once in place.
