Installation Notes:
- For vehicles originally equipped with 3/8″ crossmember bolts, open existing holes on the frame to 1/2″. If you prefer to retain 3/8″ fasteners, upgrade the installation hardware to Grade 8 bolts and hardened flat washers.
- Some minor contact between the floorplan and the crossmember may occur due to body bushing settling and deterioration, or a bowed floor pan. Usually, this is not a problem. A hydraulic floor jack with a wood cushion will correct a bowed floor.

AWESOME Look and Quality
Color: Brown, Size: 2Tier60in
I love these shelves and have bought additional for other areas in the house. I love the look of the industrial pipes, the color of the shelves is perfect, they are sturdy and hold a lot of weight. They are somewhat difficult to assemble, but it's expected as hanging shelves are never fun to hang. I love them. If you are on the fence, just do it :)

Nice, but a bear to install
Color: Black, Size: 3Tier48in
Quality product that looks good on our shiplap wall of the wet bar space. The install was a real trip and extremely difficult. You definitely need 2 or more people to install as the direction tell you to put the entire item together, then hang on the wall. This makes it impossible to do yourself.

Exactly what I was looking for
Color: Brown, Size: 3Tier48in, Color: Brown, Size: 3Tier48in
Very sturdy shelves and super easy to put together. I would put the shelves together starting with the bottoms then after it’s put together tighten everything up also starting from the bottom.

Great buy
Great shelf base! The price is great and it does the job. I just got the actual shelves from Lowe’s and they work great. I used for my teen son’s room and he loves them!
