3" Stem Rigid Caster
- 3 inches (74 mm) diameter wheel
- 150 pounds (68 kg) loading capacity
- 2.5Mph maximum speed
3 inches rigid stem caster with a loading capacity of 150 pounds (68 kg) and a maximum speed of 2.5Mph. The stem-mount is made with a rubber bushing that expands into a 28 mm steel pipe to keep the wheel in place. You will need to secure the wheel by placing it on a connector with WF-U5/16 U-Bolt (included with the caster). See the Installation Steps tab for more information on how to install W-3EF casters.
Bolt size M12 (12 mm) Length 2 1/4" (57.15 mm)
Use the F-BUS component when this caster is used with the EP-96-ST pipe.
3 inches casters are made for:
- More or less long trips (30 to 60 feet)
- Frequent use (40 to 80 times a day)
- Carts weighting less than 400 pounds
- Narrow carts (between 16 and 24 in. wide)
For more frequent use or longer trips, we recommend considering the W-4EF caster.
For carts that will go outside, roll on ramps or damaged floors, it's preferable to use 6 inches casters.
All casters are equipped with a precision ball bearing.

- Ensure you have the following parts:
- 1x W-3EF
- 1x WF-U5/16 U-bolt - included with the caster.
- 2x WF-U5/16 nuts - included with the caster.
- 1x WF-U5/16 metal plate - included with the caster.
- 1x 28mm pipe of your choice
- 1x Ratchet Wrench 3/4 in.
- 1x Ratchet Wrench 5/16 in.
- Ensure that the structure is levelled when supported by the pipes that will be wheeled. Otherwise, the height difference might cause the structure to sway.
- Flip the structure for a better access to the bottom pipes.
- Unscrew the 3/4 in. bolt underneath the plate of the caster using the wrench.
- Tighten the nut located on the top of the stem for the rubber bushing to expend until it barely fits inside the pipe.
- Insert the wheel rod completely inside the pipe. Help yourself with a mallet if needed.
- Tighten the same 3/4 in. bolt using the wrench 3/4 and let the wheel rotate until it grips firmly inside the pipe.
- Place the WF-U5/16 metal plate between the pipe and the caster and aligned it with the corresponding openings.
- Insert the WF-U5/16 U-bolt in the openings in order to trap the tube inside the U-bolt.
- Tighten the WF-U5/16 nuts with the U-bolt using the wrench 5/16.
