Buying Guide

Mounting interface compatibility

Verify the accessory uses a 1" ball or compatible socket system if you need interchangeability with RAM-style arms and pods

Clamp type and rail fit

Choose between a Tough-Claw or small clamp base depending on rail diameter and whether you need a heavy-duty grip for vehicle or boat rails

Arm length and articulation

Longer swing arms or rod-and-socket assemblies provide greater reach and adjustability for chartplotters and monitors in tight garage or cockpit layouts

Base footprint and mounting surface

Select a rectangular, pod, or rail-clamp base depending on available flat surface area or if you must attach to round rails or posts

Material and corrosion resistance

Look for marine-grade or coated materials when mounting electronics in moist or automotive environments to reduce corrosion over time
