Keep your chair steady when it matters most with this slip-on caster stopper, designed specifically for rollerblade-style desk chair wheels. Printed in TPU, it combines strength, flexibility, and floor protection in a simple, reliable design. The cradle clips over the wheel to prevent forward and rolling while maintaining a low-profile shape that avoids tripping hazards. Its slightly oversized channel ensures a secure snap fit, and the flat textured base grips the floor without leaving marks.
