About this item:

Chair casters: environmentally friendly PU casters, with good mute effect and protect the floor. You can set the casters as gravity brake wheels or universal wheels through the two switches "NO" and "OFF".

Pressure brake: "NO" is the gravity brake setting for opening the casters. Set to the "NO" switch, when a child over 15kg sits on a chair, the casters will automatically brake due to pressure.

Sliding freely: The "OFF" of the dual-purpose pressure caster is designed for automatic brake closing. When using "OFF", the office chair/swivel chair/student study chair can rotate flexibly.
Caster size: 2 inches of casters have a diameter of 50mm. The installation height of the casters is 58mm. The diameter of the plunger is 11mm.

Easy to install: The design of the plunger makes it easier to install the casters and is very easy to install. Used at the bottom of the chair, easy to move.
