SafeRacks ceiling mount hanging storage system. 4 x 8 ft with 600(800) lb storage capacity in white. There's a 14guage steel frame with a heavier gauge mesh frame as the shelf. I bought a group of these and they have been a life saver. Can hang from 24 to 46 inches or less if you trim the hanger rods. I have three shelves at 46in and two at 16in above garage door. Have one left over, never been opened. This includes the accessory below shelf hangers. This is the heavy duty model. I can sit on one without a squeak and I'm with throwing distance of 300lbs . They have a cheaper model with 300lb capacity. I opted for the safer ones.
Pretty easy to install, just bolt supports to rafters. Many videos on line. Everyone loves them.
Comes in two boxes, one ~24 x 3 x 48. The other ~6 x 3 x 48. They have some heft to them but you install in sections so it's not bad.
$200 +tax at Amazon and Costco.
