These in my opinion are THE best arms to go with... they are MUCH more versatile than the "L" arms.WAY more customizable. A+

Customer Reviews
Overall rating: 5.0 / 5 from 26 reviews.
Hi Beastgrip! The Lt/Rt Mounts are excellent! One possible issue is while they work perfectly on the iPhone 17 Pro's cage, on the BeastMod, only the Lt side has 1/4-20 hole/pegholes for the Lt Mount. The Rt side of the BeastMod does not have 1/4-20 hole/pegholes for the Rt Mount. There may be times I might want to hand-hold the BeastMod as well. I am sure I can work around this, but you might consider remedying this by giving the BeastMod a place to attach the Rt Mount (even if it means only fitting one of its two pegs). If you would like to discuss this you can contact me personally via Lkgraves111@gmail.com. Thank you!
TH!
Very solid piece. But since I’m using it with an older cage (xs iPhone) I had to place some rubber pieces between the cage and the arm due to the pin slots. Overall happy on the design and use.
The Beastcage for iPhone 16 Pro Max is everything you think it should be! I included the LT and RT sidemounts when I bought the cage and I'm glad I did. Love them!
Even though it’s not listed to work with beastgrip pro where there is a will there is a way. Wanted more of a grip and this mount works perfect with or without side handle.
Good product!

Items are great!

As usual, robust build quality. Immaculate finish and adds so much versatility to a rig!
merci! service client incroyable
I've been using your products for a few years now and have recently added to my current setup. The Beastcage for my iPhone 14 Pro Max is the heart and soul of my production. The filter adapter used for my circular polarizer gives me greater image control. The benefits of this and more can be seen in productions like the one below (follow the link). https://youtu.be/gIphar9xdMg Best regards and keep up the great work, Kevin Dove
Added something new to my photography gear
This bracket was recommended by support to add a side handle to the left side of the Beastgrip Pro, and it does so very nicely! I especially love the rosette and tons of mounting holes. Well designed!
Solid. A fantastic accessory Keeps the cage light so you don’t need an outer cage.
Very solid and well built, attached easy peasy on my Beastgrip Very very happy with the purchase!
Awesome build quality and in a pinch these work just fine as handles.
Great products
