Self-braking Casters, for Se Chairs, set Of 5

When weight is applied to the chair, the caster automatically de-brakes allowing normal mobility. The 2" dual wheel caster is constructed of nylon-reinforced fiberglass for exceptional strength and durability. The wheel has a polyurethane coating making it suitable for hard floors. Non-locking.
