Zebra RAM Βραχίονας διπλής βάσης - Μέγεθος C κοντό

When a standard-length socket arm leaves too much play or fails to fit in a tight cockpit, this short C-size double socket arm from RAM Mounts changes the geometry. At just 3.69 inches overall, it brings two 1.5-inch ball bases closer together, creating a stiffer, lower-profile connection that resists vibration and accidental drift. The single spring-loaded knob tightens both sockets at once, so you can reposition a tablet, handheld, or marine display with one hand and lock it down in seconds. Built from marine-grade powder-coated aluminum, it shrugs off salt spray, UV, and the kind of abuse that turns lesser mounts into corroded scrap. For anyone running RAM C-size components on a boat, ATV, forklift, or patrol vehicle, this arm is the missing link between a good mount and a rock-solid one.

Highlights

• Short 3.69-inch overall length reduces leverage and vibration compared to standard arms
• Compatible with all RAM C-size (1.5-inch) ball bases and sockets
• Single spring-loaded knob adjusts both sockets simultaneously for fast one-handed operation
• Marine-grade powder-coated aluminum construction resists corrosion in saltwater and industrial environments
• Supports devices up to 10 lbs (4.5 kg) when paired with appropriate C-size bases
• Backed by RAM Mounts' lifetime warranty

In daily use

Imagine you are running a 10-inch tablet on a fishing boat. The engine vibrates, the hull slams, and every wave tries to knock your screen out of alignment. A standard-length arm acts like a lever, amplifying that motion. This short arm shortens the lever, keeping the device closer to the mounting surface and dramatically reducing bounce. The spring-loaded sockets grip the ball bases firmly, and the single knob lets you tilt or rotate the device without loosening two separate adjustments. When you need to remove the device, the quick-release socket pops open with a press. The black powder-coated finish not only looks professional but also prevents pitting and flaking, even after seasons of exposure. Whether you are mounting a GPS on a tractor, a card reader in a delivery van, or a display on a sailboat, this arm delivers the rigidity and reliability that heavy-duty applications demand.
