Ulanzi extension arm mount for DJI Ronin-S / Ronin-SC | SB5308

The Ulanzi extension arm mount SB5308 is an accessory designed for DJI Ronin-S and Ronin-SC handheld gimbals. It extends the reach of the gimbal’s grip to improve handling, leverage and accessory placement. The mount fastens to the gimbal body to provide an additional mounting point for monitors, microphones, lights or a secondary handle, enabling more stable operation in run-and-gun shoots and multi-operator setups.

Advantages

The extension arm mount offers a compact and rigid solution to increase control and balance without permanently altering the gimbal. Its construction provides secure attachment and predictable leverage, helping to reduce operator fatigue and improve smoothness during pans and tilts. By adding an extra mounting point close to the gimbal, the accessory enables more flexible accessory positioning and easier access to controls while shooting.

Suitable for

• Handheld video shooting with DJI Ronin-S or Ronin-SC
• Run-and-gun filmmaking and fast setups
• Attaching external monitors, microphones or LED lights
• Two-handed operation and improved stabilization

Key specifications

• Compatibility: DJI Ronin-S and Ronin-SC gimbals
• Function: extension arm / extra mounting point
• Material: durable metal alloy (rigid construction for stable support)
• Mounting: attaches directly to the gimbal body for additional grip or accessory placement
• Finish: matte surface to reduce reflections and provide secure handling

How to use

Attach the extension arm mount to the compatible points on the Ronin-S or Ronin-SC following the gimbal’s accessory mounting instructions. Secure the mount with the included fasteners or thumbscrews until it is rigid and does not shift. Mount accessories such as a monitor, microphone or light onto the arm using their standard attachment points. Test balance and re-tune gimbal motors if necessary to compensate for added weight and maintain optimal stabilization.

Usage recommendations

For best results, install the extension arm before balancing the camera on the gimbal and perform a motor calibration if required. Use lightweight accessories when possible to avoid overloading the gimbal’s payload capacity and check that all fasteners remain tightened during extended shoots.
