Manfrotto 038 Double Super Clamp

You can use a Superclamp with flat or round surfaces.

It will clamp to any pole or column under 1.75". Just be careful not to crush the carbon fiber as these clamps to have a good amount of clamping force.

Very similar products. I like Manfrotto as a company because they seam to be very meticulous with their products in general. The lever gives you great power and they do ship their 035 model with the stud. Does the Avenger model come with a stud? I did not get the impression I would have as much clamping power with the rounded knob from Avanger. I hope this helps you in making a decision Good luck

There are five holes arranged in a quincunx. I find the central hole is UNC 1/4" 20. One pair of opposite holes appear to be M5. The other pair seem unthreaded. Perhaps alignment holes for an unknown accessory? I would like to find proper specs for these holes.

100% look into the following item that will support both fixed and telescopic cross bars. Impact U-Hook Cross Bar Holders for Super Clamp - Pair BH #IMVPAUPP • MFR #VPA-UPP https://bhpho.to/3oZ1tcj

If the jaws open wide enough, it may be able to attach it. How securely is another thing. Maybe if you hang something light. I use mine on auto poles which are round & clamp attaches securely enough to hang a flash head. Best of luck.

if you purchase the Impact Short Double Female Stud for Super Clamps with 1/4"-20 & 3/8"-16 Threads, B&H # IMSRP103, you should be able to connect the Manfrotto 035RL Super Clamp with Standard Stud to the 1/4"-20 or 3/8"-16 male thread on the top of your tripod head.

The clamp can hold up to 33 lbs. If using the 1/4" threads as the connect to what is being mounted to the clamp, a load of no more than 2-4 lbs is recommended.
