4" ESD Rigid Plate Caster

The EW-4PF 4 inch caster features a rigid plate with a loading capacity of 250 lb (113.4 kg) and a maximum speed of 2.5 mph (4.02 km/h). This caster is anti-static, making it ideal for environments where static discharge must be managed or prevented, such as in the electronics industry and medical device manufacturing. Typical applications include situations where equipment or products are exposed to static electricity.

To secure the caster to your structure, ensure you have two WF-UP, two WF-LOW, four M8-35B, and four M8-N. Refer to the Installation Steps tab for detailed installation instructions.

4 Inches Casters Are Ideal For:

• Longer trips (up to 100 feet)
• Higher frequency trips (100 to 150 times a day)
• Carts weighing more than 400 lb (181.44 kg)
• Larger carts (over 24 inches wide and 48 inches long)

For heavy-duty uses, consider the EW-6PF caster.

All casters are equipped with precision ball bearings. For carts used outdoors, on ramps, or on damaged floors, 6 inches casters are recommended.
