RAM Ball Adapter for Humminbird Piranha, Eagle & Lowrance (RAM-B-107-1BU)

Included:

• 1 x RAM Ball Adapter for Humminbird Piranha, Eagle and Lowrance (RAM-B-107-1BU)

The RAM-B-107-1BU adds a 1-inch B-size ball to a compatible fishfinder mounting bracket. Its marine-grade aluminium plate connects to a separately sold RAM B-size double socket arm, letting you choose a rail, clamp or drill-down base for your setup.

This is the adapter plate only. The fishfinder, original device bracket, socket arm and mounting base are not included. Check that you have suitable bracket-to-plate fasteners; RAM does not specify a universal fastener pack with this adapter.

Compatibility

• Humminbird Piranha MAX 10, 15 and 20
• Humminbird PiranhaMAX 4 with its original compatible mounting bracket
• Eagle Cuda 128, 168, 240 and 240i; FishEasy 240 and 320C
• Lowrance X-4 and X-4 Pro

Match your exact model and the holes in its original bracket to the RAM plate drawing. The PiranhaMAX family name alone does not confirm every model or portable/in-dash configuration. Check other versions, including 4 DI and PT, before ordering. This plate is different from RAM-B-107BU.

Completing your mount

Help

Retain the original compatible device bracket and its adjustment hardware. Select fasteners for the actual bracket and plate thickness, without fouling the device or cables. Follow the Humminbird PiranhaMAX 4 installation guide for its original bracket assembly; this is device documentation, not a RAM adapter assembly guide.

Check the mounted device, bracket and accessories, reach, rail strength, cable slack and expected wave shock or vibration. The stated ratings do not guarantee every custom installation. Choose a larger mounting system when the load or use requires it. This passive component includes no electrical connection or transducer mount.

Installation photos show a fishfinder, original bracket and fasteners for illustration; these are not included. Covered by the RAM limited lifetime warranty, subject to manufacturer terms.
