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 blue non-marking elastic rubber tyre 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 400kg and stands 240mm tall.\u003c\/p\u003e\u003ch3\u003eWhy it works\u003c\/h3\u003e\u003ch4\u003eDirectional lock – swivel or straight at the flick of a foot\u003c\/h4\u003e\u003cp\u003eWith 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.\u003c\/p\u003e\u003ch4\u003eBlue non-marking elastic rubber tyre\u003c\/h4\u003e\u003cp\u003eThe blue elastic rubber tyre is designed not to leave marks on floors, so it is widely used on hospital, laboratory, retail and food-area floors. The tread (hardness A70) absorbs bumps, grips well and runs quietly, and it copes with temperatures from -20°C to +80°C.\u003c\/p\u003e\u003ch4\u003eRoller bearing for easier rolling\u003c\/h4\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDirectional lock holds the swivel head straight ahead\u003c\/li\u003e\n\u003cli\u003eBlue non-marking elastic rubber tyre, quiet running\u003c\/li\u003e\n\u003cli\u003eRoller bearing, 400kg per castor, 1,200kg for a set of four\u003c\/li\u003e\n\u003cli\u003e140 x 110mm top plate, M10 fixings\u003c\/li\u003e\n\u003cli\u003e240mm total height, 157mm swivel radius\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhere it's used\u003c\/h3\u003e\u003cp\u003eLong hospital and care home trolleys, linen and meal-delivery trolleys, laboratory and pharmaceutical carts, catering and food-service trolleys, and warehouse and distribution trolleys that travel long straight routes and then manoeuvre in tight spaces.

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 blue non-marking swivel, total lock and fixed castors in height, 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 400kg, choose a heavy-duty castor.\u003c\/p\u003e\u003ch3\u003eInstallation, use and care\u003c\/h3\u003e\u003cp\u003eHold 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.\u003c\/p\u003e\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs a directional lock the same as a brake?\u003c\/strong\u003e\u003cbr\u003eNo. It stops the castor swivelling but the wheel still rolls, so the trolley runs straight.
