The ones seen in this instructable are 21 apart and 4 tall give or take because of bar placement.
Diy parallel bars for physical therapy.
Load capacity under normal physical therapy use.
Decide how far apart you want your parallel bars to be spaced.
Lay one of the 10 x 10 cm 4 x 4 inch boards flat on the floor then lay another parallel to the first.
Raise your p bars by inserting the poles and couplings between the bases and bars.
Width adj 1 1 2 one piece stainless steel handrails.
The best way to figure this out is measure your shoulder width.
This version is obviously more involved than the pvc design but the extra work and cost will yield a really nice looking set of parallettes that are strong enough to handle just about anything you throw at them.
Width adj floor folding parallel bars with double stiffening rails.
Intended for physical therapy use only not for gymnastics use.
In this step you ll want to determine how tall you want your parallel bars and also how wide apart you want the bars to be.
Cut four lengths of the wooden posts at 4 feet long.
Easy height adjustment with spring loaded plungers and numbered height strip.
A common spacing is around 60 cm 2 feet apart to accommodate the different shoulder widths of everyone using the bars.
