• Ideal for curved windows and windscreens, including helicopter transparencies
• B size double socket arm with retention knob for easy adjustment without over-loosening
• Double socket technology allows near-infinite adjustment angles
• Arm connects to any RAM 1" ball base
• Powder-coated steel and high-strength composite construction
• Lifetime warranty

Works With

Because each suction cup pivots independently, this base holds securely on curved surfaces where a rigid dual-cup base wouldn't seat properly. A single spring inside the arm opens the end sockets so you can pivot the ball-and-socket connection, and the retention knob lets you fine-tune the angle without the arm working loose.
