DuraGates Large 4-Wheel Trolley for Bi-Fold Door - 375G

This large four-wheel trolley carries bi-fold gate panels on sealed bearings that roll smoothly along overhead or cantilever track. The steel carriage tolerates the dynamic loads created when panels fold and stack, maintaining alignment without binding or chatter. Four wheels share the payload evenly, preventing the single-point failures that plague smaller two-wheel units. Galvanized or corrosion-treated components ensure the trolley performs through wet winters and dusty summers alike. It is the mechanical heart that makes large bi-fold gates fold gracefully rather than fight their operator.

Features

• Four-wheel carriage distributes bi-fold panel loads
