Bar spacing, base width, and whether it moves when you do
A dip station holds two parallel bars at chest height and a power tower adds a pull-up bar, a back pad and usually knee-raise arms above it. Both are frames carrying a person’s full weight through a small footprint, and stability is the whole review. The published user weight is the headline figure, and on this shelf it is worth treating as a static figure — a dip is entered by dropping into it, and the load at the bottom of the movement exceeds body weight. The bar spacing is the figure that decides whether the station suits the shoulders using it, and the good designs make it adjustable and publish the range: too narrow and the elbows flare, too wide and the shoulder takes the load. Bar diameter and its covering decide how long the grip lasts. Height adjustment matters for the pull-up bar on a tower — the useful figure is the height under the bar, which has to clear the user’s head with arms extended and still leave the floor reachable. Then the part that separates a usable tower from a wobbling one: the base. Its width and depth in centimetres, whether the uprights are braced diagonally, whether the feet are rubber and whether the frame can be bolted down — a tall tower on a narrow base moves during a dip, and that movement is what makes people stop using it. The assembled weight is a proxy for all of it: on this shelf, heavier is steadier. We compare grip width, height range, grip diameter, base footprint and max user weight.
57 × 38 × 73 cm, 100 kg per bar, 200 kg total
A pair of low parallettes that publishes its dimensions and splits its rating: 100 kg per bar, 200 kg for the two together. Two separate stands rather than a frame.
Best for: Floor work and dips where a tall frame will not fit or is not wanted
Folding triangular frame, 7 heights, 150 kg
A free-standing tower that folds, with seven height positions and two barbell rests built into the frame — a station that also holds a bar.
Best for: A room where a tower has to disappear between sessions
Height, length and spacing all adjustable, 500 kg
Dip bars adjustable in three directions — height, length and spacing — usable as a pair or singly, with the highest published figure in this family at 500 kg.
Best for: Calisthenics where the bars need to be set differently for different movements
170–220 cm in 12 steps, 205 kg
The tallest and most adjustable tower here: 170 to 220 cm across twelve published steps, at 205 kg, with padded elbow and back supports.
Best for: A garage or a tall room where a full hang is the point
79–94 cm adjustable, 157.5 kg
An adjustable pair of dip bars with a published height range of 79 to 94 cm and a capacity given in both units: 157.5 kg, or 350 lbs.
Best for: Somebody who wants the dip height set rather than accepted
60 × 30 mm steel, 1.5 mm wall, 62 cm spacing, 90 cm
The station here that publishes its steel and its spacing: a 60 × 30 mm section at 1.5 mm wall, bars up to 62 cm apart, at a height of 90 cm.
Best for: Somebody who wants to check the spacing against their own shoulders first
106.5 cm; title says 300 kg, detail says 200 kg
A 106.5 cm station whose own listing gives two different capacities — 300 kg in the title and 200 kg in the specification. Both are reported here, because that is what is published.
Best for: Somebody who wants the height published and will accept the load ambiguity
100 cm base, 2 mm steel, 28 kg frame, 204 kg
A tower that publishes its base length, its steel thickness and its own mass — and compares all three, in its own listing, against unnamed competitors.
Best for: Somebody choosing a tower on how firmly it stands rather than on a capacity
Only the specifications at least four models out of five state. A column that is more empty than full compares nothing.
