What the 237HD Flex Arm Is

The Manfrotto 237HD Heavy-Duty Flex Arm is a 21.6-inch adjustable support arm built for photography and studio rigging. It connects via a hexagonal stud to the Super Clamp 2915 and offers a 3/8" female thread on one end plus a 5/8" stud with 1/4-20 male thread on the other. The larger 0.7" diameter gives it more rigidity than the 2896 model.

Who This Suits and Who Should Look Elsewhere

This arm suits photographers and videographers mounting lightweight fixtures such as a 150W Fresnel, small flashes like a Canon 580EX, or a lightweight webcam onto a Super Clamp. It is not for buyers who need to support loads heavier than 1lb or who require rigid positioning beyond a 90-degree angle without sagging.

What to Check Before Ordering

Verify that your Super Clamp is the 2915 model to accept the hexagonal stud. Confirm the threads on your light or accessory match the 3/8" female or 1/4-20 male ends provided. Ensure the 21.6" reach and 0.7" diameter fit your workspace and that the 1lb capacity covers your intended fixture.

Questions about this item

Does the 237HD flex arm need a Super Clamp 2915 to mount to a stand or surface?

Yes, the hexagonal stud is made to fit the Super Clamp 2915, so that clamp is required for standard mounting.

Can a 150 W Fresnel stay rigid on the 237HD when angled past 90 degrees?

The arm may bend if the load is positioned beyond a 90° angle, so keep the Fresnel closer to vertical for best support.

How can I confirm the 3/8" female thread and 5/8" stud with 1/4-20 male thread are engaging correctly after setup?

Attach a light or camera to each end; both connections should thread fully without play and the arm should hold position without slipping.
