Use the F-BUS component when this caster is used with the EP-96-ST pipe.
4 inches casters are made for:
- More or less long trips (30 to 50 feet)
- Frequent use (20 to 50 times a day)
- Carts weighting less than 400 pounds
- Narrow carts (between 16 and 24 in. wide)
EW-4ESB has a non-electric conductivity version:Â W-4ESB
For more frequent use or longer trips, we recommend considering the W-6PSB caster.
For carts that will go outside, roll on ramps or damaged floors, it’s preferable to use 6 inches casters.
