The COR757 2 section boom arm can be fitted to the COR751, 752 & 753 light stands. The counter balance weight can be adjusted to accommodate the different weights of the range of Interfit lights. The brass end stud is reversible with both 1/4 and 3/8th threads.

I got this as part of a larger kit a while back and it's use has exceeded the original needs. Now I use it mostly on location, handheld by an assistant, and with modified flashguns. Because it's light (being made of rigid aluminum tubing) it's not terribly difficult to hold out while in full extension in order to get more challenging shots. And the lock stops on both the head and the extension part have never slipped even when under heavy load. A perfect complement to this would be the Lastolite LL LS2499 Waist Holder. It makes holding this boom over long jobs easier and more stable. While aluminum will bend a bit, if you're mounting a huge softbox to a monolight it might make more sense to get the chrome boom from Westcott since it's very rigid (I use this in studio) and can easily manage the heaviest loads. I know that I will get another one of these booms eventually, and I have no hesitation recommending it...
Recently, I decided to create a home studio setup with three simple lights and a backdrop. I needed a boom to be able to place a large softbox directly over the camera, or in situations where I needed overhead support for a hair light. I placed the boom assembly (with my Photogenic PL06 monolight attached) on a sturdy light stand, secured it using the supplied plastic clamp, and placed the counterweight on the end of the boom. The mass of the counterweight immediately snapped the cheap plastic clamp holding it in place, and the whole assembly fell off of the light stand to the floor, strobe head and all. Instead of this model, I would highly recommend purchasing one of Adorama's other boom systems, such as one from Bogen/Manfrotto or Adorama's own house brand. The Interfit boom just wasn't up to the job, unless you only need to support a small strobe head or tungsten light. Even then, it's a risky venture.
