Tripod Ball Head Mount Ulanzi SB9880 Arca-type 75mm base, 1/4" and 3/8" mounts, vertical and horizontal rotation

Ulanzi SB9880 is a ball-head style tripod mount designed for precise positioning of cameras and lenses. The head features an Arca-type compatible 75 mm base and accepts both 1/4" and 3/8" mounting screws, enabling use with standard tripod plates, clamps and accessories. The mechanism allows secure locking and smooth adjustment for both vertical and horizontal rotation, making it possible to change camera orientation quickly and hold the required angle firmly.

Advantages

The SB9880 provides a compact solution for photographers who need versatile orientation control. Its Arca-type 75 mm base ensures compatibility with many quick-release systems and clamps, while the dual-thread mounts (1/4" and 3/8") increase compatibility with tripods, monopods and third-party accessories. The ball-head mechanism allows continuous 360° horizontal rotation and a wide range of vertical tilt, with reliable locking for stable support of photographic gear.

Suitable for

• Landscape, architecture and studio photography where precise framing is required
• Macro and telephoto setups when switching between horizontal and vertical orientations
• Mounting cameras or lenses on tripods, monopods or clamp fixtures with Arca-compatible plates
• Video shooting that benefits from stable panning and angle adjustments

How to use

Attach the SB9880 to a tripod, monopod or clamp using the appropriate thread (1/4" or 3/8"). Mount an Arca-compatible plate or quick-release camera plate onto the 75 mm base and secure it according to the plate’s locking method. Use the main ball clamp to adjust the head position for the desired vertical tilt and horizontal rotation, then tighten the clamp to lock the camera in place. For finer control of rotation tension, adjust the tension control as provided by the head design. Ensure all connections are tightened before releasing the camera from support.

Usage recommendations

Use an Arca-compatible plate matched to the 75 mm base for best stability and quick mounting. Select the correct screw size when attaching the head to support equipment and periodically check mounting screws and clamps for tightness. Avoid exceeding the load capacity recommended by the equipment you pair with the head, and keep the head free of grit and moisture to preserve smooth movement.
