Choosing a semi truck cup holder
Start with the use: a drink while driving needs a different solution from a drink beside you during a parked break.

For the truck in motion
Steadi is not a vehicle-mounted holder or a substitute for the truck’s intended drink storage. It is freestanding, with no claim to restrain a drink during braking, turns or vibration. Consult the exact truck manual and appropriate equipment guidance for driving use.
For a parked sleeper-cab break
Steadi can widen a compatible drink’s footprint on a firm, level and fully supported spot while parked. It slips onto the drink and can move with you between a suitable sleeper table and a rest-stop table. No clamp or permanent installation is involved.
For a factory holder replacement
Identify the truck’s model, model year and actual installed interior before looking for a replacement. A product advertised as a semi truck cup holder is not automatically compatible with every cab. Steadi does not replace a factory part or expand a molded opening.
For a clamp or mounted accessory
A mounted accessory needs its own suitable attachment point, load guidance and installation instructions. A clamp being tight is not evidence of vehicle compatibility. Check the manufacturer’s intended use and the truck’s guidance before selecting hardware.
Choose only what solves your problem
If you need an insert or a driving mount, choose an appropriate product for that purpose. If you want a portable wider base for a drink beside you while parked, check Steadi’s 2–3.15-inch container-base range and 5.2-inch footprint first.
