Large Locking Chair Caster, 60 mm
A toe-brake completely locks the caster wheels to prevent the chair from rolling. On a slick floor the chair can still slide if pushed, but it will not roll. In the unlocked position the casters roll easily. It's usually only necessary to lock 2 or 3 wheels to effectively stop a chair from rolling.
Available with hard tread for carpeted floors or soft tread for hardwood and tile floors.
