Thread adapter for studio mounting

The Manfrotto adapter converts a standard 1/4" x 20 thread into a smooth 3/8" mounting stud. It lets photographers and videographers attach larger lighting heads or accessories to smaller light stands or clamps. The knurled grip provides secure hand tightening without tools.

Sustained load on the 3/8" stud

The 20 mm mounting area height and 25 mm overall height keep the connection compact under continuous weight. The all-metal construction resists stripping during repeated rigging and de-rigging cycles. It is not suited for loads that exceed the 1/4" base thread rating or for permanent structural installations.

Questions about this item

Does the 25 mm overall height add noticeable leverage or wobble when the adapter is used on a light stand all day?

The adapter is a solid metal stud with a 25 mm total height including the knurled grip, so it adds minimal leverage and stays rigid under continuous studio lighting loads.

What thread size must my existing light or camera gear have for this adapter to screw on?

Your equipment needs a standard 1/4" x 20 thread; the adapter screws onto that and provides a 3/8" mounting stud for larger accessories.
