Square Post Clamp Mount RAM Mounts RAM-101U-247-4

The RAM-101U-247-4 is a square post clamp mount featuring a double socket arm, a 2.5" diameter round base with the universal AMPS hole pattern, and a 4" clamp base that secures to posts up to 4 inches wide. Constructed from durable materials with rubber ball-and-socket technology, the mount reduces shock and vibration while allowing wide-angle adjustability for optimal device positioning.

Advantages

The clamp base wraps around posts up to 4" wide and tightens with the supplied nuts and bolts for a stable attachment. The 2.5" round base uses the AMPS hole pattern for compatibility with many RAM Mounts accessories. The rubber ball-and-socket joint absorbs vibration and permits nearly infinite adjustment for precise viewing angles.

Suitable for

• Mounting electronics and equipment on square or rectangular posts up to 4" wide
• Outdoor and industrial installations requiring a robust clamp mount
• Applications where vibration damping and flexible positioning are needed

Key specifications

• Model: RAM-101U-247-4
• Base diameter: 2.5" round base with AMPS hole pattern
• Clamp capacity: fits posts up to 4" (maximum width 4")
• Mount type: double socket arm with clamp base

How to use

Place the clamp base around the square or rectangular post (maximum width 4"), align the clamp plates, and secure them by tightening the supplied nuts and bolts until the mount is firm. Attach the 2.5" round AMPS-pattern base to the compatible RAM accessory or device using the appropriate fasteners. Adjust the ball-and-socket joint to the desired viewing angle, then lock the socket by tightening the knob or bolt.

Recommendations

Ensure the clamp is tightened evenly and checked periodically for security, especially in high-vibration environments. Use appropriate corrosion-resistant hardware for outdoor or marine applications and confirm compatibility of attached accessories with the AMPS hole pattern.
