Teardrop vs Keystone vs Structural vs Cantilever Rack
The four rack styles we make and sell, side by side: how the beams attach, the sizes, ratings and delivery, and what each one is chosen for.
To tell selective rack apart, look at the slots punched up the front of an upright. Teardrop-shaped slots mean teardrop rack. Keystone-shaped slots mean keystone, also called Republic rack. Beams bolted to heavy C-channel uprights mean structural rack. Cantilever has no front columns at all: arms reach out from a row of towers.
Teardrop and keystone parts do not mix, so when you add to a system, match the style you already have. Not sure what you have? Send us a photo of an upright and a beam end and we will identify it.
