Frog Bull Frog Casters

For the person really on the GO! Ultra Sports incorporate a lightweight stembolt for additional weight reduction on your chair. In many cases, this makes Ultra Sports shock absorbers lighter than the rigid forks they replace. But don't think for a second that you sacrifice anything in performance. The hollowed-out design is ten times stronger than an ordinary, solid stembolt inserted into your chair.
Available in 1" and 1.5" wide models.
Available for 3", 4", 5" and 6" caster wheels.
Fits most manual wheelchairs from manufacturers like Invacare, Quickie, E&J, Colours and more.
Polymer shock absorber flexes to soften bumps and cut vibration.
Easy replacement of existing rigid caster forks.
Hinged pivot point allows you to roll up and over obstacles.
Choice of axle position--for wheel size and seat height.
Please specify caster housing to floor measurement and wheelchair model upon ordering.
