Accessory Compatibility

This product provides a mounting ball only. Compatibility depends on the connection used by your accessory.

• Before ordering, confirm:
• The required ball diameter is exactly 17 mm or 20 mm
• The accessory has a matching female socket, or you have the correct double-socket arm
• The socket can tighten securely around the ball
• The accessory and device are suitable for vehicle use
• The combined size and weight are appropriate for the mounting position
• The accessory does not interfere with the seat, passenger, airbag, or driver visibility

Ball sizes are not interchangeable. A 17 mm socket will not properly fit the 20 mm option, and a 20 mm socket will not properly fit the 17 mm option.

Some manufacturers use proprietary socket shapes, collars, or locking systems even when the advertised diameter is similar. Please compare the connection dimensions before ordering.

• Vehicle Compatibility
• ✅ Fits supported Mercedes no-post headrests shown in the listing photos
• ❌ Does not fit AMG-style sport headrests
• ❌ Does not fit traditional headrests with two exposed metal posts

Please send a clear photo of your headrest before ordering if you would like help checking vehicle compatibility.
