Manfrotto Adapter Stud, Diameter 3/8"and 1/4"

The Manfrotto 149 3/8" Adapter is a 50 g brass converter that transforms a 1/4"-20 male threaded tip into a 3/8"-16 tubular stud (20 mm long), enabling secure attachment of larger heads, arms, or accessories to compact stands or clamps.

The Manfrotto 149 adapter bridges 1/4"-20 threads to a robust 3/8"-16 tubular stud in a polished brass body that resists corrosion and wear. The 20 mm length provides just enough extension for clearance, while the knurled grip ensures hand-tightening without tools. Ideal for location gaffers or studio techs needing to mount ball heads, magic arms, or monitors on mini stands, clamps, or QR plates—lightweight at 50 g, it’s the perfect pocket-sized solution for hybrid photo/video kits demanding instant, fail-safe compatibility.
