TollRoads Fastrak Flex Holder (SoCal)

New updated design. High-temperature plastic that won't melt.

Note: this holder only fits TollRoads Fastrak transponders from 2020 or newer, offered to Southern California (Irvine) residents. The transponder measures 3 15/16" x 1 15/16" x 3/8" thick. Please measure if you are unsure.

The holder uses the included suction cups to secure your TollRoads Fastrak Flex transponder to your windshield. No tape or glue needed. Works in cars without headliners, such as convertibles and sports cars. Easily removed and moved to another vehicle, which makes it perfect for using your own transponder in rental cars to save money.

Did your transponder stickers melt during a hot summer and fall off? This holder is tested from 100°F summers to -5°F winters. It won't melt off the windshield on a hot day and set off your car alarm. Perfect for small business owners who run fleet vehicles and delivery trucks: install one in each van or truck.

Caution: if you use a windshield reflector, avoid tucking it right up against your Fastrak transponder. Please leave some air space in between.

3D printed from PETG. Includes 1 holder with 2 suction cups.

Installing

Remove the TollRoads-supplied adhesive, slide the transponder selector to position one, and carefully slide the transponder into the holder. Clean your windshield with Windex or another glass cleaner, wipe dry and attach. If you've cleaned your windshield since installing, wash the suction cups with dish soap and water to remove any residue.

Orders typically ship the next business day.

Buyers have installed this in Teslas, Lucids, ID.4s, Mach-Es, e-trons, Polestars, Leafs, Ioniqs and more. Even motorcyclists have mounted it on their windscreens.
