RAM Medium Dual Suction Round Plate Bundle (MM-B-DUALSUCTION-MEDIUM-ROUND)

Included:

• 1 × RAM Double Suction Cup Base (RAM-B-189BU)
• 1 × RAM Standard Socket Arm Two Round Bases B (RAM-B-101U): arm plus two RAM-B-202U round ball plates

A fixed dual-suction platform paired with a medium B-size arm and two round ball plates. One round plate connects to the ball-less suction platform; the second provides the holder-side AMPS attachment.

Choose a compatible device holder or cradle separately. The holder and device are not included.

Specifications

• Ball size: B size, 1 inch (25.4 mm).
• Fixed suction platform: two 3.3-inch (83.8 mm) cups; total width 7.95 inches (201.9 mm).
• RAM-B-189BU is supplied without a ball; this bundle uses one of the two RAM-B-202U plates included in RAM-B-101U as the lower ball connection.
• Medium arm: 3.73 inches (94.7 mm) overall; 3 inches (76.2 mm) socket-to-socket.
• RAM-B-101U arm-and-two-plate assembly: 5 inches (127 mm) overall height before fitting it to the suction platform.
• Both round plates: 2.5 inches (63.5 mm) diameter; four-hole AMPS 1.181 × 1.496 inches (30 × 38 mm), plus three-hole 120-degree pattern on a 1.812-inch (46 mm) circle.
• Platform materials: powder-coated steel and high-strength composite. Arm and round plates: marine-grade aluminium.
• RAM-B-189BU includes assembly hardware, four #8-32 × 1/2-inch machine screws and four #8-32 thin Nyloc nuts.
• RAM’s published B-size component ratings: up to 2 lb (0.91 kg) for standard use and 1 lb (0.45 kg) for heavy-duty use. Mounting surface, leverage, vibration and the full holder-and-device load must also be assessed.
• Packaging may vary; all listed components are genuine RAM.
• Warranty: RAM’s limited lifetime warranty is subject to its terms; suction-cup rubber is a wear item and is excluded. This component bundle does not extend that warranty to a device, vehicle or installation.

Help

Use both suction cups on one clean, smooth, flat, non-porous area with enough room for the full platform. This fixed platform is intended for a flat surface; curved glass may need a different, pivoting base. Confirm lower-plate attachment, fastener engagement and loaded stability during assembly. Two suction cups do not increase the B-size component load rating.

Check the selected holder’s hole pattern, thread and required screw length before assembly.

Compatibility

The supplied output is a four-hole AMPS plate with a B-size ball. Use it with a flat-backed holder that accepts this pattern and suitable fasteners. A holder with an integrated 1-inch B-size ball can fit directly into the arm instead of the supplied upper plate. A C-size ball requires a matching C-size arm.
