The Palram Canopia Twin Shelf Kit is a lightweight shelf system that quickly attaches to the inside of a greenhouse frame. The Shelf Kit includes two 10" x 24" overlapping shelves and can be repositioned easily within the greenhouse.
Bought 2 sets of shelves. The shelves work great once installed. BUT there is a BIG PROBLEM! The bolt heads on the bolts supplied DO NOT FIT in the tracks as instructed. They are exactly 10mm too wide. We had to file all of them down to use them, What a pain!!!! This kit is supposed to be made for Palram greenhouse which is what my greenhouse is. You need to send correct size bolt heads.
