Round Expanding Adapters provide a secure and reliable method of mounting bolt hole castors to round hollow tube applications. Designed for industrial, commercial and material handling equipment, these adapters expand inside the tube to create a strong fixing point without the need for welding or drilling.

The expanding mechanism is attached to a bolt hole castor using the threaded stem. As the bolt is tightened, the adapter expands against the internal wall of the round tube, creating a firm and stable connection. This makes installation quick, easy and highly effective for mobile equipment, trolleys, carts and transport systems.

To ensure the correct fit, the internal diameter of the round tube should be measured before selecting an expanding adapter. The adapter must be able to fit inside the tube while providing sufficient expansion range to create a secure fixing.
