The Envoy 3-inch red polyurethane castor with plate-mount and brake lock gives workshop trolleys and carts a secure, floor-friendly wheel with a foot-operated stop — stocked at Multi Trade Combines, Guwahati, price on request.
Most buyers arrive looking for castors and leave realising they needed braked castors all along. The Envoy 3-inch Red PU Plate Castor with Brake is the version that prevents a loaded trolley from drifting when it is parked. On workshop floors in Guwahati's industrial belt — AT Road, Bharalumukh, and Sarusajai — slight floor gradients are common. Without a brake lock, an instrument cart or material trolley left on an incline will roll, sometimes into operators or delicate equipment.
The polyurethane wheel resists chipping on rough concrete, leaves no black scuff marks on painted or tiled floors, and absorbs minor floor irregularities to reduce vibration on sensitive loads. The red colour on Envoy's PU range denotes a medium-duty formulation — appropriate for workshop trolleys, storage racks, and mobile workbenches carrying loads up to 400 kg on a four-castor platform.
The plate-mount fitting suits fabricated steel trolleys and shelving units. Four bolts through the top plate secure it rigidly. Ball-bearing construction lowers rolling resistance and extends service life. The brake engages with a foot tap and releases with a heel press, keeping both hands free during loading and unloading.
Facilities managers in tea estates, auto-repair garages, and cold-storage units across Northeast India are regular buyers of this item. Pair it with the plain plate version (no brake) on the leading two castors for easy steering while keeping the rear two braked for parking stability.

The 3-inch (75 mm) Envoy PU plate castor with brake lock typically carries 80–100 kg per castor depending on the grade. For a four-castor trolley that gives a 320–400 kg platform capacity. Always confirm the specific load rating from the stamping on the castor yoke before loading.
The brake version adds a foot-operated tread-lock mechanism that clamps the wheel and prevents it from rolling while engaged. This is essential on tipping trolleys, instrument carts, or workbenches on sloped workshop floors. The plain plate version offers free rolling only and suits trolleys that are always in motion or on level surfaces.
