The SR (Sealed Road) Towbar Mount is designed to work with the Glider Pro 3 eco-system. The base has a rubber layer to help prevent slipping and it has a locking thumbscrew as well.
During our testing we torture tested the mount on bumpy country roads and dirt roads while weighted with a 3 kg (7pound) payload without any failure of any sort. Yes, we over engineered this mount well and truly but please follow the pre-cautions below:
Please bare in mind that the SR stands for 'Sealed Road' and it shouldn't be used on dirt roads, off-road or any driving where significant shocks are being transmitted through the car.
Be careful not to over-tighten your tow ball bolt as this bolt can apply enough pressure to damage the mount. First tighten lightly and then mount your rig to it and then gently pull on the gimbal to see if the mount will move easily. Continue doing this until a force of over 10kg (22pounds) is needed to budge the mount.
Always secure your rig with a separate safety line to protect it in case of catastrophic failure.
When not in use we suggest removing it from your tow bar as excessive UV light and inclement weather will reduce it's strength.
