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.
Floors & use
Rubber tread · working temperature -20°C to +80°C
- Cushions the load and soaks up vibration
- Quiet on most surfaces
- Copes with uneven floors, thresholds and outdoor use
- Good grip on smooth floors
- Takes more effort to push than nylon under heavy loads
- Oils and solvents shorten tyre life
Details & FAQs
For workshop and warehouse trolleys that need to steer freely in tight spaces but also run dead straight down long aisles, this 200mm directional lock castor gives you both in one. It is a swivel top plate castor with a foot-operated catch that locks the swivel head in the straight-ahead position, turning it into a fixed castor until you release it. It has a black rubber tyre with a ribbed tread on a black polypropylene centre running on a roller bearing, a zinc-plated pressed steel housing and a 140 x 110mm top plate. Each castor is rated to 200kg and stands 240mm tall.
Why it works
Directional lock – swivel or straight at the flick of a foot
With the catch released the castor swivels a full 360 degrees like any swivel castor, so the trolley turns easily in lifts, doorways and bays. Engage the catch and the swivel head is held straight, so the trolley tracks true over long runs without the front wandering. The directional lock holds the swivel head only; the wheel still rolls. It is not a parking brake – choose a total lock castor where the trolley must be held still.
Black rubber tyre – quiet, grippy and hard-wearing
The black rubber tyre (hardness A85) absorbs small bumps, grips well and runs far more quietly than a hard nylon or steel wheel. It copes with temperatures from -20°C to +80°C. Black rubber can leave dark marks on pale or polished floors, so for hospitals, shops and clean areas choose the blue non-marking version instead.
Roller bearing for easier rolling
The large wheel runs on a roller bearing rather than a plain bore, so a loaded trolley takes less effort to start and keep moving, and the wheel wears more evenly over time.

Where it's used
Warehouse and distribution trolleys, long workshop and stock trolleys, garden-centre and builders' merchant trolleys, and platform trucks that travel long straight routes and then manoeuvre in tight spaces. Best on concrete, sealed concrete, resin and other hard floors where occasional tyre marks are not a concern.
Choosing the right option
A common layout is one or two directional lock castors at the front, fixed or swivel castors at the back, and total lock castors wherever the trolley must be parked. Fitting one directional lock castor on the front corner you steer from is often enough; engage it for straight runs and release it for cornering. This castor matches the 200mm black rubber swivel, total lock and fixed castors, all 240mm tall, so any mix sits level. Check you have a flat area at least 140 x 110mm under each corner and allow 157mm of swivel clearance. For the load, add up the weight of the item and everything on it and divide by three rather than four; if the answer is over 200kg, choose a heavy-duty castor.
Installation, use and care
Hold the plate flat against the base and fix it through all four holes with M10 bolts and nuts. Fixings are not included. Fit the castor so the lock catch faces outwards where your foot can reach it. To lock, push the trolley a short way so the wheel trails straight, then engage the catch. Check the fixings after the first few weeks, keep the wheel and catch clear of threads and debris, and wipe clean with a damp cloth. Keep the rubber tyre away from oils and solvents.
Frequently asked questions
Is a directional lock the same as a brake?
No. It stops the castor swivelling but the wheel still rolls, so the trolley runs straight. To stop a trolley rolling, use total lock or braked castors.
How many do I need on a trolley?
Usually one or two at the front. One on the front corner you steer from is enough for most trolleys.
Will the black wheel mark my floor?
Black rubber can leave dark marks on pale or polished floors, especially when turning under load. For those floors, choose the blue non-marking version.
What size bolts do I need?
The plate holes are 10mm, so use M10 bolts and nuts. Fixings are not supplied.
