The Zebra 3PTY-RAM-238-MAG88U is an 88mm diameter C-Size magnetic ball base from the RAM Tough-Mag mounting system — a third-party mount accessory sold under the Zebra accessories catalog for use with compatible Zebra mobile computers and devices. If you're building out a vehicle mount or workstation mounting solution for a Zebra mobile computer, this component provides the magnetic ball interface that anchors the RAM arm system to a ferrous surface without drilling.
The C-Size ball designation is a RAM Mounting Systems standard — C-Size balls are intended for heavier devices and larger arm systems, making the 3PTY-RAM-238-MAG88U appropriate for tablet-class or larger mobile computer installations rather than lightweight handhelds. The 88mm magnet diameter directly determines holding surface area and, in turn, magnetic retention force: a larger base means more contact area against a steel surface, which matters in vehicles or environments with vibration.
The 3PTY-RAM-238-MAG88U (often searched as 3PTY RAM 238 MAG88U) is a RAM Mounting Systems component sold through the Zebra accessories channel. Verify C-Size compatibility across your full arm-and-cradle assembly before ordering — mixing C-Size and B-Size components in the same stack will not mate correctly. Confirm that the target mounting surface is ferrous steel; the magnetic base will not adhere to aluminum vehicle panels or stainless steel surfaces with low magnetic permeability. For guidance on pairing this base with the right arm and cradle, review the mounting accessories selection or contact pre-sales engineering.
Q: What RAM ball size does the 3PTY-RAM-238-MAG88U use?
A: The 3PTY-RAM-238-MAG88U uses a C-Size ball interface, which is RAM Mounting Systems' designation for heavier-duty arms and larger device holders — appropriate for tablet-class mobile computers rather than lightweight handheld scanners.
Q: What diameter is the magnetic base on the 3PTY-RAM-238-MAG88U?
A: The magnetic base is 88mm in diameter. A larger base provides more contact area against a ferrous steel surface, improving retention in high-vibration environments such as forklifts or delivery vehicles.
Q: Will the 3PTY-RAM-238-MAG88U work on an aluminum vehicle dashboard?
A: No. The magnetic base requires a ferrous (steel) mounting surface. Aluminum panels and some stainless steel grades are not magnetic and will not retain the base.
Q: Can I mix C-Size and B-Size RAM components in the same assembly?
A: No. RAM ball sizes are not interchangeable — a C-Size ball base must be paired with C-Size compatible arms and heads throughout the assembly. Mixing sizes will prevent proper mating and is a common source of returns.

The 3PTY-RAM-238-MAG88U is the component most installers reach for when a fleet operator wants repositionable Zebra terminal mounts in steel-cab vehicles without committing to drilled brackets. The 88mm magnetic base is the key spec here — not because bigger is always better, but because that diameter gives you enough retention surface to handle the vibration profile of a loaded forklift or a box truck on a gravel yard without the base walking off the surface mid-shift.
Technical Highlights:
Deployment Considerations:
The 3PTY-RAM-238-MAG88U is the right call for warehouse fleet deployments running Zebra tablet-class terminals in steel-cab forklifts or reach trucks, where non-destructive mounting and daily repositionability are operational requirements rather than preferences.
