Often, we are trying the increasing or enlarging concepts.
But, here, no pills or other strange accessories needed! ^_^
will help you by a useful reduction!
Reducer for thread 3/8" to 1/4"-20
With its internal female diameter of 1/4" and its external male 3/8" diameter, you will be able to screw this small adapter in any device with a 3/8" female thread (as some microphones, LED lamps, flashes, monitoring screens, controller...), and fix the accessory on your tripod, its quick release plate or any other supports with a 1/4"-20 male thread.
And, if your accessory has a bigger 5/8" female thread, add this other Adapter ADP-58M38F. Just screw the ADP-38M14F inside.
The photo below shows the ADP-38M14F reducer screwed inside the Adapter ADP-58M38F.
This allows a conversion 5/8" to 1/4"
A very useful accessory, all in metal conception.
