The boom arm support is a telescoping aluminum pole with adapters on either end for the 3 and 4 Way Clamp System. With the addition of two clamps it helps you stabilize your boom rig for extra safety.
I shoot classical guitar videos and use Kupo C-stands to hold main, fill and hair lights. Works great for trained models—they keep their chins up—but sitting guitarists play with their heads down, forming unsightly shadows on lower face and neck. So I use a small softbox below the mains to fill in unsightly shadows and the Kupo 4-Way Clamp is perfect for securing the softbox to the C-stand riser, eliminating the need for another light stand.
Sturdier and more solid than a super clamp when you have the right size 'tube' to latch on to. It is, admittedly, more of a special-purpose item, not as versatile as a super clamp, but when you attach it to a riser column (for example) it really becomes part of the riser.
I bought Kupo’s system for attaching accessories such as arms, light heads, cameras, etc., to their C-stands: 4-Way Clamp, Baby 5/8-Inch (16mm) Receiver and this Baby 5/8-Inch (16mm) Stud. The Baby 5/8-Inch (16mm) Stud is ideal for securing a second light head to the C-stand riser, eliminating the need for another light stand. Like the other components, it is well made and engineered.
I bought Kupo’s system for attaching accessories such as arms, light heads, cameras, etc., to their C-stands: 4-Way Clamp, Baby 5/8-Inch (16mm) Receiver, 66mm Baby 5/8-Inch Stud and this 108mm Baby 5/8-Inch Stud. The baby studs are ideal for securing a second light head to the C-stand riser, eliminating the need for another light stand. Like the other components, it's well made and engineered.
To go with this Kupo makes a couple of studs that lock into the slots in the clamps collar . It's a handy way to attach other things - flags, lights, reflectors - to a C-stand or a pipe with a one to 1.4 inch diameter. Another accessory for this clamp is an arm that supports a C-Stand arm.If you think you need a better solution than a Mafer clamp or a Cardellini clamp for this one purpose this does the job, but really it's a specialty item.
I use the Kupo 4-Way Clamp and Baby Receiver to attach a softbox to a C-stand riser, eliminating the need for another light stand. The Baby Receiver slides into a notch on the clamp and is secured with a threaded collar. It’s strong enough to hold a Magic Arm and video light so I’m happy. The only minor gotcha is the fit in the notch is a little loose no matter how tight I make the collar. It’s not coming out but tolerances are a little sloppy.
Kupo products are some of the best I've used and this is not exception!
Well built. As good as American. Just make sure to know diameter of pipe. This is a bigger one. Fits on stage 3 C stand but not on stage 1 or 2 as they are too small to grip. Great for making meace arms out of C Stands especially if you have Kupo Baby 5/8-Inch (16mm) Stud. You can use a 40 inch arm or two with a Cardellini instead of strap.
Buen soporte de aluminio para montar un reflector en un tripié. Hay que tomar en cuenta que el tornillo superior de 5/8" es grande y no es muy estandard en la mayoría de la mayoría de los reflectores. El envío fue rápido y sin problemas.
