Disclaimer:
This product uses strong magnets, but it must be attached to a ferrous (steel) surface for proper function. It will not stick to aluminum, plastic, or non-magnetic surfaces. If your truck bed or mounting area is lined with a drop-in liner or thick bed coating, the magnetic hold may be weakened or not work at all.
For best performance, we recommend mounting directly to a clean, exposed metal surface. If that’s not possible, please consider using the screw-mount option or securing the holder another way. All holders have been tested on steel surfaces and will hold the intended bottle type securely under normal conditions.
If your holder falls off, it’s likely due to insufficient metal exposure or liner interference, not a defect in the magnet or design.
