There are two main categories of castors: furniture castors; and heavy-duty
Furniture castors are designed for interior use. Ball castors are great for
rolling on carpet, twin-wheel castors are great on any surface, and are
available hooded or unhooded. You can also get them with brakes to help your
furniture items stay put. They can be fixed to furniture via a stem fitting or a
plate. Bed castors are available as replacements, and trolley castors are
excellent on tile floors.
Heavy-duty castors are designed for punishing use in the garage or shed. They
are available in fixed or swivel types, in black or grey rubber (grey doesn’t
leave marks) and hard nylon. The rubber types are great on hard surfaces and
roll quietly. The hard nylon wheels handle maximum loads and are longwearing.
Selecting the right castor is as easy as rolling into your nearest hardware
