The fit is perfect and is a sold mounting system
Custom fit for 2022 Tacoma, fit exactly. Very sturdy mount and took seconds to install. All metal with the exception of a adjustment knob. Quality hardware. More expensive than a lot of mounts but most are cheap plastic and are not nearly as solid and sturdy as the Offroam.

FINALLY a decent phone mount!!!
I’ve tried about 5 different phone mounts in my 2018 Tacoma and ended up throwing them all away. They’re either too bulky, too weak to hold the phone, awkward or just won’t stay in place. I won’t install a holder that requires adhesive or screws into the dash (or anywhere) in my truck. This holder is the answer. Fits perfectly, doesn’t damage your vehicle. Holds the phone really solidly. This is a very sturdy mount. It’s a bit pricy in comparison to other phone mounts out there. IMO, it’s worth every penny. Materials are far superior to your typical mount, which I’m sure drives up the manufacturing costs. Again, worth every penny. Also, it’s a small business based in the US. Love supporting our small businesses. GREAT MOUNT!!!
