PROMATE TRANSHOLD-EXT Secure Smartphone Holder / Transparent Design / Windshield, Dashboard & Air Vent Mounting / Auto Clamping with One-Touch Release / Extendable Arm with Adjustable Viewing Angles / High-Stability Cradle / Durable ABS, Silicone, Acrylic, TPU & Metal Construction / TRANSHOLD-EXT / TRANSHOLD-EXT

The Promate TRANSHOLD-EXT is a transparent smartphone holder that mounts to a windshield, dashboard or air vent. An auto-clamping cradle grips the phone as you place it and releases at one touch, while a telescopic arm sets the viewing distance. It is built from ABS, silicone, acrylic, TPU and metal.

The body of the TRANSHOLD-EXT is made from clear material rather than opaque plastic, so the mount itself takes up far less of your sightline through the windscreen. On a windshield mount the frame is the part that blocks your view, not the phone, which is why a transparent structure changes what the mount actually costs you in visibility.

The cradle clamps automatically as the phone is pushed in and lets go with a single touch. That makes it a one-handed action in both directions, which is the whole point of a car mount: fitting and removing the phone should never need a second hand or a look away from the road.

The same holder fits three positions: suction to the windshield, onto the dashboard, or clipped into an air vent. Cabin layouts differ enormously, and the best sightline in one car is a blind spot in another. Having all three options means the mount adapts to the vehicle rather than the other way round.

The arm telescopes between 99mm and 145mm, giving 46mm of reach adjustment. Extension is what brings the phone off a deeply recessed windscreen or forward from a vent set back under the dash, so the screen sits where you can read it at a glance rather than where the mounting point happens to be.

The arm offers several tilt positions so the screen angle can be set independently of where the mount is fixed. Getting the tilt right is what removes windscreen reflections off the display and keeps navigation readable in direct sun, which is exactly when a badly angled screen becomes unusable.

The cradle jaws span 55mm to 98mm, which is the measurement that decides whether your phone fits. Check the width of your handset with its case on, since a thick protective case is the usual reason a phone that should fit does not. That range covers compact handsets through to large-format models.

Overall height ranges from 70mm at its lowest to 200mm fully raised. That vertical travel lets you lift the phone clear of a dashboard lip or drop it below the driver's eyeline depending on where you have mounted it, without changing the mounting point itself.

The mounting base is 106mm tall by 66mm wide. Measure the flat area you intend to use before fitting, particularly on a textured or curved dashboard where a suction base needs an unbroken surface to seal against. Vent-mounted installations need less clearance than dashboard ones.

The TRANSHOLD-EXT combines ABS, silicone, acrylic, TPU and metal, with metal reinforcement through the cradle itself. Silicone and TPU handle the contact surfaces so the phone is not gripped by bare plastic, while metal in the load-bearing cradle is what keeps the phone from shaking loose over rough road surfaces.
