## Long description

The RAM Mounts Square Post Clamp Base is a heavy-duty mounting solution engineered for secure attachment to square posts measuring up to 4 inches in width. Constructed from high-quality, black powder-coated aluminium, this base is built to withstand demanding environments while maintaining a sleek, professional appearance. It integrates a 2.25-inch D-size rubber ball, which is specifically designed to provide superior vibration dampening and shock resistance, ensuring that your mounted equipment remains stable and positioned exactly where you need it.
Advantages
This clamp base offers exceptional durability and reliability for heavy-duty applications. The use of marine-grade aluminium ensures long-term resistance to corrosion and wear, making it suitable for both indoor and outdoor use. The integrated D-size rubber ball technology is a standout feature, as it effectively absorbs vibrations and impacts, protecting sensitive electronic devices from damage. Its versatile design allows for a secure grip on square surfaces, providing a rock-solid foundation for various RAM mounting arms and device holders.
Suitable for
Industrial machinery and warehouse equipment
Commercial vehicle mounting systems
Heavy-duty electronic device support
Outdoor installations on square structural posts
This product may not be suitable for mounting on round or irregular-shaped posts, as the clamp is specifically contoured for square surfaces. Additionally, if your application requires a smaller ball size for lighter equipment, the D-size ball may be oversized and incompatible with smaller RAM components without the use of specific adapters.
Key specifications
Material: Powder-coated aluminium
Ball size: 2.25 inch (D-size)
Compatibility: Square posts up to 4 inches wide
Color: Black
To install the clamp, position the two halves of the base around the square post and align the mounting holes. Insert the provided hardware and tighten the bolts evenly to ensure a firm, non-slip grip on the post. Once the base is securely fastened, you can attach your desired RAM mounting arm to the rubber ball and adjust the angle to your preferred viewing or operating position.
What to consider before purchase
Verify that your mounting surface is a square post with a maximum width of 4 inches.
Ensure that your device or mounting arm is compatible with the 2.25-inch D-size ball.
Check the available clearance around the post to ensure the clamp can be tightened properly.
Usage recommendations: Regularly inspect the mounting hardware to ensure all bolts remain tight, especially in high-vibration environments. Periodically clean the rubber ball surface to maintain maximum friction and grip for the mounting arm.
