RAM Mounts replacement tether rubber for -UN7 / -UN10 / -UN12 X-Grip phone holders (RAM-TETHER1U)

Why is a safety tether for the X-Grip smartphone holder useful?

Anyone who uses their smartphone in a RAM Mounts X-Grip holder knows the situation: during strong vibrations, shocks or rapid maneuvers the phone can start to slip despite the X‑Grip's springy clamping. This is exactly where the replacement safety tether RAM-TETHER1U comes in. It is stretched over the corners of the smartphone in addition to the existing holder, creating a second level of security. The result is a significantly firmer hold on the device without restricting usability. Motorcyclists, boat operators and users in open cockpits in particular benefit from this additional protection. The safety tether is suitable for all common smartphone sizes used in compatible X‑Grip holders. Installation is extremely simple and tool‑free. Thanks to the elastomeric material, the tether adapts flexibly to different device dimensions and retains its tension even with prolonged use. As a replacement part it is a practical and cost‑effective solution to maintain the protection of the phone holder over the long term and to prevent the smartphone from falling out.

Which X-Grip phone holders are compatible with the tether?

RAM Mounts’ safety tether is universally compatible and fits three different X‑Grip phone holder models. The standard version UN7 is designed for smartphones with a width of up to 82.55 mm and is suitable for most common mobile phones. The large variant UN10 accepts devices up to 114.3 mm wide and is therefore ideal for larger smartphones and phablets. In addition, the tether is compatible with the wireless charging holder UN12, which in addition to holding the phone also enables inductive charging. This broad compatibility makes the replacement safety tether a versatile accessory for different usage scenarios. Whether in a car, on a bicycle, on a motorcycle or on a boat—the tether always provides the necessary hold. Even with frequent swapping between different smartphones, the securing function remains reliable. The tether can be easily replaced and is attached in seconds, so the holder is always ready for use.

What material is the X-Grip safety tether made of and how durable is it?

RAM Mounts uses high‑strength elastomeric rubber for the safety tether, specially developed for use under extreme conditions. This material is characterized by high tear resistance, UV resistance and temperature tolerance. Even with prolonged exposure to sunlight, rain or cold, the tether retains its elastic properties and does not become brittle or porous. The robust material ensures that the tether functions reliably over long periods without losing tension. For frequent drivers and professional users who use their holder daily, the safety tether is a cost‑effective way to increase smartphone protection permanently. If the original tether shows signs of wear after intensive use, it can be quickly and easily replaced with the spare tether. Investing in a new tether is far cheaper than replacing a damaged smartphone. This keeps the X‑Grip holder always ready for use and provides maximum security for valuable mobile devices in any environment and in any weather.
