Who Should Buy SmallRig 1138 Clamp?
Good fit
Choose this SmallRig clamp for mounting to a rod, tube, table, frame, or tripod without drilling. Its dual ball head and 1/4″-20 screw accommodate cameras and accessories.
It also fits creators who use action cameras alongside other compact accessories. The included action-camera mount and 1/4"-20 screw cover multiple attachment needs, provided the complete rig stays within the capacity guidance.
Who should skip it
Skip it if your planned rig exceeds the 1.5kg capacity or cannot be secured with a clamp on an available rod, tube, table, frame, or tripod.
For use in dynamic scenarios, do not treat the clamp as the only restraint; include the recommended safety rope in your setup.
SmallRig 1138 Clamp: Setup and Buying Considerations
Flexible mounting surfaces
The clamp's range of mounting surfaces makes it useful when a camera needs to sit on a desk, rod, tube, frame, or tripod rather than on a dedicated stand.
The locking knob secures the clamp without drilling, so it is suited to temporary content stations and adaptable workspaces.
Positioning and compatible gear
The clamp's dual ball head comes with a 1/4″-20 screw for mounting cameras, webcams, monitors, lights, microphones, and action cameras. That makes it an option when one clamp needs to hold one of these pieces of gear.
Capacity and secure installation
Treat 1.5kg as the upper capacity for the mounted setup and account for every attached accessory.
In moving or vibration-prone use, attach a safety rope as directed and verify that the clamp is firmly locked before placing equipment above people or delicate surfaces.
Materials and package contents
Aluminum and stainless steel construction suits buyers looking for a metal clamp assembly, and the package pairs the super clamp with an action-camera mount.
Confirm that these included pieces match the attachment points and working space in your particular setup.
