Secure T-12 LED Tube Mounting

The Kupo clamp fits T-12 LED tubes measuring 38 to 42 mm in diameter. Its aluminium die-cast body and rubber-lined jaws grip the tube firmly without marring the finish. A steel spring keeps the jaws closed under vibration. Two mounting threads are provided: a 1/4"-20 female socket on the base and a 3/8"-16 female socket on each side.

For studio and location lighting crews

Gaffers and videographers who need quick, reliable attachment of T-12 tubes to stands, arms or rigs will appreciate the secure lock and dual thread options. The clamp supports loads up to 4.4 lbs, so heavier fixtures or large modifiers exceed its rated capacity. Users with tubes outside the 38-42 mm range must choose a different clamp size.

38-42 mm tube diameter compatibility

This single measurement decides whether the clamp fits your LED tube. Measure the tube before ordering; the spring-loaded jaws only accommodate diameters between 38 mm and 42 mm.

Questions about this item

What tube diameters does the 38-42mm clamp actually grip?

The jaws are sized for T-12 LED tubes between 38mm and 42mm, so any tube in that range locks in without play.

Which threads are on the clamp for attaching arms or stands?

A 1/4"-20 female thread sits on the bottom and a 3/8"-16 female thread on each side for standard grip gear.

How much clear space is needed to mount the clamp on a tube?

The die-cast aluminium body with rubber liners fits straight onto the tube; allow room for the side threads and the spring-loaded jaws to close fully.
