Replacing an old castor? Measure between the centres of two fixing holes along the long edge, then across the short edge, and compare with the hole centres above. Allow the swivel radius as clear space around each castor so it can turn freely.
Load check
How we work it out: on a real floor one castor is often carrying little or nothing, so we share the weight across one fewer castor than you fit (with 3 castors, across all 3). Tick the box to add a 30% margin for rough use.

Details & FAQs
Light Duty Top Plate Castor
This compact 50mm swivel castor combines a tough black polypropylene wheel with a zinc plated pressed steel swivel housing, carrying up to 55kg per castor on display units, light furniture, cabinets and small trolleys.
With an overall height of just 72mm, it keeps fitted units low to the floor, and the small 50 x 50mm top plate with four 6mm holes fits neatly under narrow bases. Polypropylene shrugs off water, oils and most cleaning chemicals, so the castor stays easy to look after.
Why Choose This Castor
- ✓ Low 72mm overall height for low-profile units
- ✓ 55kg load capacity per castor
- ✓ Hard polypropylene wheel that resists water, oil and chemicals
- ✓ Zinc plated pressed steel housing for corrosion resistance
- ✓ Full 360 degree swivel with a tight 50mm swivel radius
- ✓ Small 50 x 50mm top plate for narrow bases and frames
Load capacity is per castor. For a set of four, allow for uneven floors by planning on three castors carrying the load.
Where It Works Best
Shop fitting and retail displays, office and home furniture, storage cabinets, plant stands, small workshop trolleys and equipment stands. Best suited to smooth indoor floors where a compact, low-profile castor is needed.
Frequently Asked Questions
How much weight can this castor carry?
Each castor is rated at 55kg. A set of four is best used for loads up to around 165kg, allowing for uneven floors.
What size screws or bolts do I need?
The top plate has four 6mm holes on 36 x 36mm centres, so M5 or M6 bolts, or No. 10 wood screws for timber bases, are a good fit.
Is the wheel suitable for hard floors?
Polypropylene is a hard wheel that rolls easily on smooth floors. For delicate floors such as laminate or wood, a rubber wheel will be quieter and kinder to the surface.
How tall is the castor once fitted?
The overall height from floor to top plate is 72mm.
Is there a braked version?
Yes, a matching 50mm braked swivel castor is available, so you can fit two braked and two plain swivel castors to hold a unit in place.
