SKU CH-DZRY-ZWGCX

Converts 1/4"-20 female threads to 3/8"-16 male threads with a 1.18" flange for stable equipment mounting

  • Converts 1/4"-20 female to 3/8"-16 male threads for versatile mounting
  • 18" flange increases surface area for stable heavy-gear connections
  • Precision threading prevents wobble and misalignment during use
  • Durable construction withstands frequent studio and location setups
  • Quick adaptation saves time when configuring camera and lighting rigs

Thread Adapter for Camera and Lighting Gear

The Kupo KS-064 converts a 1/4"-20 female thread to a 3/8"-16 male thread, letting you mount accessories with the larger fitting onto smaller threaded equipment. It is built for photographers, videographers and lighting professionals who need a reliable way to connect mismatched thread sizes on set. The 1.18" flange adds a broad contact surface that resists wobble when heavier items are attached. This adapter suits anyone expanding a kit without replacing existing stands or brackets.

Passive Mechanical Component

As a purely mechanical bushing the adapter draws no power, generates no heat and makes no noise during operation. Its solid construction means there are no moving parts to wear out or vibrate under load. The precision threading keeps the connection tight without the need for tools or locking mechanisms. Performance is consistent regardless of how long the shoot lasts.

Upgrade from Improvised Thread Adapters

This bushing replaces makeshift solutions such as stacking multiple reducers or using tape to secure loose threads. The jump is worth it when you regularly switch between 1/4"-20 and 3/8"-16 gear and need a single, repeatable connection that will not shift. It is not for users who only work with one thread standard and never encounter the other.

Questions about this item

How do I install the Kupo KS-064 adapter bushing, and what step prevents wobble?

Screw the female 1/4"-20 side onto the tripod or light stand male thread, then thread your 3/8"-16 female accessory onto the male end; tighten until the 1.18" flange seats fully against the mount surface to eliminate play.

What maintenance or replacement will the Kupo KS-064 adapter need later?

No routine maintenance is required; inspect threads periodically for wear or cross-threading, and replace the bushing if the flange cracks or threads no longer hold securely under load.

What limit appears first when the Kupo KS-064 adapter is used continuously with heavy gear?

The 1.18" flange contact area and thread engagement depth determine the maximum safe load; exceeding this causes flex or thread stripping before any other failure mode occurs.
