  • 4 inches (100 mm) diameter wheel
  • 250 pounds (113 kg) loading capacity
  • 2.5Mph maximum speed

4 inches rigid plate caster with a loading capacity of 285 pounds (68 kg) and a maximum speed of 2.5Mph. Ensure you have two WF-UP, two WF-LOW, four M8-35B, and four M8-N to fix the caster on your structure. See the Installation Steps tab for more information on how to install W-4PF casters.

4 inches casters are made for:

  • Longer trips (100 feet maximum)
  • Higher frequency trips (100 to 150 times a day)
  • Carts weighting more than 400 pounds
  • Larger carts (greater than 24 in. wide and 48 in. long)

For heavy duty uses, we recommend considering the W-6PF caster.

All casters are equipped with a precision ball bearing.

For carts that will go outside, roll on ramps or damaged floors, it's preferable to use 6 inches casters.

  1. Ensure you have the following parts:
    • 1x W-4PF
    • 2x WF-UP

  2. Ensure that the structure is leveled when supported by the pipes that will be wheeled. Otherwise, the height difference might cause the structure to sway.
  3. Flip the structure for better access to the bottom pipes.
  4. Ensure the pipes are parallel and have 3 1/4 in of center spacing.
  5. Place the two WF-LOW perpendicular on the pipes.
  6. Place the caster on both WF-LOW and align the openings.
