Easy, Secure Chair Fitting

The S56PK5 castors use 11 x 22mm wire-clip stems for a push-in fit in matching chair-base sockets. The wire clip helps retain the stem in the socket, making these a straightforward replacement for an existing castor with the same fitting.

Check the diameter, stem length and fixing type against your current castors before ordering.

Fits Most Standard Office Chairs

These castors suit most standard office chairs that use the matching 11 x 22mm wire-clip fitting, including compatible desk chairs and stools in offices and home workspaces. Chair fittings vary, so matching the stem is the key to selecting the right replacement.

The wheel diameter is 50mm. Check clearance and the replacement castor height when changing wheel sizes.

Non-Marking Wheels for Indoor Seating

The clear polyurethane wheels provide a non-marking running surface for indoor chairs and furniture. They help reduce wheel marks during normal use, making them a practical option where floor presentation matters.

Check suitability for your floor finish and keep the wheels and floor free of trapped grit. This twin-wheel model is supplied without a brake.

Upgrade All Five Wheels Together

The pack includes five matching castors, so you can replace all the wheels on a five-castor chair in one purchase. Refreshing the full set keeps wheel size, material and fitting consistent across the chair base.

Each castor has a stated capacity of 20kg. The castor rating does not replace the chair manufacturer’s occupant rating.
