Frequently Asked Questions
What is the difference between the diamond base and the round plate?
The diamond base (RAM-B-238U) is smaller at 2.43" x 1.31" with 2 holes — ideal for tighter mounting locations or surfaces with limited space. The round plate (RAM-B-202U) is 2.5" diameter with the AMPS hole pattern — better for flat panels and surfaces where more attachment points are needed. Both use the same 1" B size ball.
Is this the same base included in the suction cup assembly?
Yes — the RAM-B-238U diamond base is the same base that ships as part of the RAM-B-224-1U Twist-Lock suction cup assembly. It is also sold standalone for bolt-on applications.
Can I mount this on an AJK dash panel?
Yes — the diamond base works with AJK CNC dash panel mounts on UForce U10, Defender HD10, and other machines. Contact the team at Dunes 2 Dezert SXS for specific compatibility guidance.
What arm should I pair with this base?
The RAM Double Socket Arm (RAM-B-201U for medium or RAM-B-201U-C for long) connects directly to the B size ball on this diamond base for a complete 2-piece mounting system — just add a device holder.
Are the mounting hole dimensions standard?
Yes — the two holes on the diamond plate are sized for standard mounting hardware. Contact the team at Dunes 2 Dezert SXS for specific hole dimension details if needed for a custom bracket.
