HEAVY-DUTY CUP HOLDER BASE - Made of automotive grade ABS plastic. This innovative design works with most cup holders. This is best suited for cup holders that are completely round. Oblong cup holders or cup holders with a mug handle cutout may be more challenging for this base. Adjustable to fit in cup holders between 2 ⅞” and 3 ⅝” in diameter. The expanding mechanism allows you to securely tighten the base in the cup holder of your choice.


SINGLE KNOB ADJUSTABLE ARM - the 3.75" aluminum stud arm easily installs with the twist of a knob for easy repositioning of your device.


AMPS PLATE CONNECTION - Industry-standard AMPS hole pattern will attach to a variety of devices.


GOOD, BAD AND UGLY CUP HOLDERS - Cup holders vary in location, size, shape, depth, and overall sturdiness. The ideal cup holder for this mount is one that is perfectly round with straight walls, not tapered. It will NOT work well with flip out or fold-out cup holders, or with cup holders that only support 2 or 3 sides of the cup. Not all cup holders are created equal and we at Tackform understand that. If you’re not happy with how this fits in your cup holder, give us a call and we’ll see if we can come up with a better solution for your particular application.
