80mm Braked Top Plate Castor – Grey Rubber Wheel, Total Lock, 70kg

For trolleys, furniture and equipment that must roll quietly, treat the floor gently and then stay firmly in place, this 80mm braked castor is a practical everyday choice. It has a grey non-marking rubber tyre on a black polypropylene centre running on a roller bearing, a zinc-plated pressed steel housing, a 105 x 85mm top plate and a foot-operated total lock brake that holds both the wheel and the swivel head. Each castor is rated to 70kg and stands 108mm tall. It suits office and school furniture, shop and stockroom trolleys, catering and cleaning trolleys, workbenches and mobile display units.

Why it works

Grey rubber tyre – quiet and floor-friendly

The grey rubber tyre is a non-marking compound, so it will not leave the dark scuffs that black rubber can, and it absorbs small bumps and runs quietly on hard floors. It copes with temperatures from -20°C to +80°C. Grey rubber is a lighter-duty wheel than the blue elastic rubber range, and is the economical choice where loads are moderate.

Roller bearing for easier rolling

The wheel runs on a roller bearing rather than a plain bore, so it takes less effort to start and keep moving under load, and it wears more evenly over time.

Total lock brake – wheel and swivel held together

A standard wheel brake stops the wheel rolling but still lets the castor spin round. This castor's foot brake locks the wheel and the swivel head at the same time, so equipment stays exactly where you park it.

• Grey non-marking rubber tyre, quiet running
• Total lock foot brake locks wheel and swivel together
• Roller bearing, 70kg per castor, 210kg for a set of four
• 105 x 85mm top plate, M8 fixings
• 108mm total height, 118mm swivel radius

Where it's used

Office pedestals and storage units, school and library trolleys, shop display units and stockroom trolleys, catering and cleaning trolleys, workbenches and light equipment stands. Suited to vinyl, tiles, laminate, sealed wood, sealed concrete and other hard indoor floors.

Choosing the right option

Choose grey rubber, as here, for quiet running and floor protection at moderate loads; the blue elastic rubber range carries more weight at the same wheel size, and polyurethane suits heavier industrial use. Check you have a flat area at least 105 x 85mm under each corner for the plate. For brakes, most equipment has total lock castors on two corners and plain swivel castors on the other two. For the load, add up the weight of the item and everything on it and divide by three rather than four, because on an uneven floor one castor is often lifted; if the answer is over 70kg, choose a larger wheel or the blue elastic rubber range. Allow 118mm of swivel clearance around each castor.

Installation, use and care

Hold the plate flat against the base and fix it through all four holes with M8 bolts and nuts. Fixings are not included. Fit the castor so the brake pedal faces outwards where your foot can reach it. Check the fixings after the first few weeks, keep the wheel and brake clear of threads and debris, and wipe clean with a damp cloth. Keep the rubber tyre away from oils and solvents. Bring equipment to rest before applying the brake.

Frequently asked questions

Will the grey wheel mark my floor?
Grey rubber is a non-marking compound, so it will not leave the dark scuffs black rubber can. Keep the tyre clean to avoid carrying grit.

What does "total lock" mean?
The foot brake locks both the wheel and the swivel head, so the castor can neither roll nor spin round.

What size bolts do I need?
The plate holes are 8mm, so use M8 bolts and nuts. Fixings are not supplied.

What is the load capacity?
Each castor is rated to 70kg. A set of four is rated to 210kg, because the load is calculated on three castors to allow for uneven floors.
