Combine with your choice of lighting, softboxes or umbrella's, will be strong enough to hold most types of lights but we don't recommend using the arm to support more than 1.5kg. The boom arm is fitted with a 5/8" spigot. Please Note The boom arm can actually be extended to nearly 140cm but we do not recommend you do this as their is not much overlap between the 2 segments which will cause stress on the lock nut between the 2 segments, instead move it back about 5cm. 6 MONTH WARRANTY ## Features - DOES NOT INCLUDE STAND - Telescopic boom arm with 2 sections extending from 75cm to 135cm - Nut lock has four different sized holes on each side to fit different stands - Hole diameters: 31, 24, 20, 17mm (please note that these the tightening method of the lock nut will compensate for a few mm with stands bigger in diameter to the hole sizes stated) - Lock nut can be rotated to supsend the lights at different angles - 2 Sandbags & hook provide counter-balance against the weight of the lights ## Images ![Studio Boom Arm & Lock Nut Extension Arm for Photography Light Stand/PhotoGeeks® / Standard Spigot Mount with 1/4" Thread - Image 1](https://m.media-amazon.com/images/I/41OvDP5HBUL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Very useful bit of gear, does the job *by P***L on Reviewed in the United Kingdom on 27 August 2015* I have used this with an 80 x120 softbox mounted parallel to to floor and this has not crept or moved. This was not with the boom arm fully extended as the soft box in question was quite heavy with the flash attached. But I have attached a smaller 60x60 softbox and I have had no problem with boom fully extended.As another person has mentioned mount the counter weight bag holding pin upwards, as the bag can jump off if mounted downwards, if you drop your light stand section down too quickly, as I have done. And use ziploc bags filled with rice to act as counter weights (2kg min) with big softboxes.Overall a good and well priced product, but why 4 stars. I found unlocking the boom arm nut, to change angle position, a bit awkward sometimes, especially with a heavyish softbox and the finish of the both locking nuts, to be not as good as my reflector holder boom locking nut. (and basically they are all made in the same factory, just differently branded)BUT it is a very useful bit of gear and I am glad that I bought it. (Supplier was excellent as well) ### ⭐⭐⭐ i felt like I needed 3 hands *by B***D on Reviewed in the United Kingdom on 2 October 2015* I have to say I think this is somewhat overpriced when compared to a lot of light stands on here and it wasn't exactly "plug and play" either. Basic quality control required!I found his very awkward at first, the problem was obvious, you can't adjust one side without the other side coming loose, i felt like I needed 3 hands!!! Anyway, I've solved the problem, a drop of lock-tite on the nut made the clamp function as 2 separate sides (no more "it all falls apart if you try to adjust it"). I also had to fix the clamp on the extender - the lock screw wasn't tight enough on the outer post so the extension rotated even when the thumb screw was tightened.Such a shame that I had to put it right, I'd have given it 5 stars in it's current configuration, but the slap dash way it had been assembled let it down. ### ⭐⭐⭐⭐ For what it's designed for it's great, but make sure the lighting you want to ... *by J***A on Reviewed in the United Kingdom on 20 February 2016* For what it's designed for it's great, but make sure the lighting you want to use with this does not exceed 2KG, otherwise it will be quite wobbly and has fallen on me multiple times due to my own error of not reading the supported weight.The clamp broke too, but I think this is related to using too heavy equipment. It's great for beauty dishes though which are much lighter than big octogon softboxes with strobes. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/91940552-studio-boom-arm-and-lock-nut-extension-arm-for-photography](https://www.desertcart.com.ar/products/91940552-studio-boom-arm-and-lock-nut-extension-arm-for-photography) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-21*
