Package Contents
Verify that all components are present before beginning installation:
- 1 x TerraClamp Heavy Duty 3-in-1 Mount (PSM11001)
- 1 x Removable Weatherproof Smartphone Case
- Stainless Steel Mounting Hardware
The weatherproof smartphone case is designed for phones up to 3.5 inches wide x 6.5 inches tall.
Setup and Installation
- Identify Mounting Location: Choose a suitable location on your motorcycle, ATV, or side-by-side with a round or square tube between 1.5 inches and 2 inches in diameter. Ensure the location provides clear visibility and accessibility for your device.
- Attach the Clamp Mount:

The TerraClamp mount features a robust clamping mechanism for secure attachment to vehicle bars.
Position the clamp mount around the chosen tube. Use the provided stainless steel hardware to tighten the clamp securely. Ensure the clamp is firm and does not rotate or slide on the tube. - Adjust the Mount Arm:

The mount arm can be adjusted to various angles and secured with a lock nut.
The mount arm can be swiveled and rotated. Loosen the lock nut on the arm to adjust the angle and orientation. Once the desired position is achieved, tighten the lock nut firmly to secure the arm. - Attach Your Device: The mount features a standard 1/4-inch screw mounting port. Attach your GoPro camera or other compatible device directly to this port. If using a smartphone, proceed to the next step for the weatherproof case.
- Using the Weatherproof Smartphone Case:

A smartphone is shown secured within the weatherproof case, attached to the TerraClamp mount.
Open the weatherproof case zipper. Carefully insert your smartphone into the case. Ensure the phone is centered and the screen is visible through the clear front panel. Close the zipper completely to ensure weather resistance. The case can then be attached to the mount arm using its integrated mounting mechanism.
Operating Instructions
- Adjusting Viewing Angle: The mount allows for 360-degree rotation. Loosen the lock nut on the mount arm, adjust your device to the optimal viewing angle (portrait or landscape), and then re-tighten the lock nut to secure it.
- Using the Smartphone Case: The weatherproof case retains touchscreen capability, allowing you to interact with your smartphone while it is protected. For optimal touch response, ensure the phone screen is clean and dry before placing it in the case.
- Internal Storage: The smartphone case includes a built-in pocket for small items like keys or cards.

The interior of the smartphone case reveals a convenient pocket for storing small essentials.
Maintenance
- Cleaning: Clean the mount and weatherproof case with a damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners that could damage the materials.
- Hardware Inspection: Periodically check all mounting hardware, especially the stainless steel components, for tightness and signs of wear. Re-tighten any loose screws or bolts to ensure the mount remains secure.
- Weatherproof Case Care: Ensure the zipper on the weatherproof case is free of debris to maintain its sealing capability. If the case becomes damaged, replace it to ensure continued protection for your device.
Troubleshooting
- Mount feels loose or unstable:
- Ensure all clamp screws and the arm's lock nut are fully tightened. Verify that the mounting surface (tube) is within the specified diameter range (1.5 to 2 inches). If the tube is smaller, additional padding may be required (not included).
- Smartphone touchscreen is unresponsive through the case:
- Ensure your phone screen is clean and dry before placing it in the case. Remove any screen protectors that may interfere with touch sensitivity. The case is designed to retain touchscreen functionality, but extreme conditions or certain screen types may affect performance.
- Phone does not fit in the weatherproof case:
- Check your phone's dimensions against the case specifications (up to 3.5 inches wide x 6.5 inches tall). If your phone exceeds these dimensions, it will not fit properly.
- Water or moisture inside the weatherproof case:
- Ensure the zipper is fully closed and free of any obstructions. Inspect the case for any tears or punctures. If damage is present, the case's weatherproof integrity may be compromised and it should be replaced.
