Swivel Gate Caster with Spring and Bracket, Medium, 100mm Wheel, 150kg Limit

A sprung caster that holds up the free end of a swing gate and turns to follow it. When a swing gate is long or heavy, the free end drops and the hinges take the strain. This caster supports that end on a 100mm wheel, and the wheel swivels on its head, so it can follow the arc of the gate rather than fighting it. A coil spring around the rod takes up small differences in ground level. The medium model has a maximum weight limit of 150kg. The wheel is 25mm wide, and the open square bracket fixes to the gate upright. The price shown is for one caster. The minimum order is 4.

Why a sprung swivel caster works

The swivel follows the swing. A swing gate moves in an arc, and a wheel that can turn stays pointed along that arc as the gate moves.

The spring keeps it on the ground. As the gate crosses small rises and dips the spring extends and compresses, so the wheel keeps its contact instead of lifting clear or digging in.

A steadier bracket. The 4mm bracket and 100mm wheel suit a medium gate that gets regular use.

Where it is used

Swing gates at trade premises, business courtyards, garden centres, agricultural merchants and estates. It is at home on concrete or block paving, and the 100mm wheel copes better than the small one with a less regular surface. Soft ground will let any wheel sink, so give it a firm strip to run on.

Specifications

Choosing the right caster

This is the middle of the three casters. Its 100mm wheel rolls over small bumps better than the 75mm, and its limit is 150kg, while the 120mm model goes to 200kg. It shares the 8mm holes at 55mm centres with the small caster, and it has a thicker 4mm bracket. Measure your gate upright against the bracket width before you order, and choose by the gate's weight and the surface it runs on. A jockey wheel in a fixed fork is the alternative if you want a heavier welded fork.

Fitting and care

Hang and adjust the gate first, then position the bracket on the free end of the gate so the wheel sits on the ground with some of the spring compressed. Mark the fixing holes, then fit the bracket with bolts to suit your gate. Fixings are not published as included. Swing the gate through its full travel and check that the wheel swivels freely and stays in contact with the ground.

Check the axle and swivel at each service and keep the rod free of grit, as a seized swivel is what stops a caster following the gate. Replace the wheel if it has flats or has started to break up.
