A four-post cage is for people who lift without a spotter. Safety bars sit below working depth so a failed squat or bench press can be walked away from, which is what makes heavy solo training possible in a garage.
The G100 Power Rack comes in white and in black, with adjustable J-hooks, safety bars and an integrated pull-up bar on a hole-punched four-post frame. The Commercial Multi Functional Power Rack adds a Smith machine, squat cage and functional cable crossover, in 150kg 2:1 or 150kg 1:1. A folding two-upright stand lives under half racks. Free standard delivery to Great Britain (Scottish Highlands and Islands included) is built into the price you see, cages included.
Pair the cage with a 2-inch bar using the barbell guide.
