The Manfrotto SYMPLA Universal Mount can be used to attach various SYMPLA and non-SYMPLA accessories to SYMPLA rods or to any other standard-size 15mm rods.
The device features an open hook design, four 3/8" screw-holes, and two
1/4" screw-holes. Into the open hooks you would slide in your rods. And
into the screw-holes you can attach pretty much any 3/8" and 1/4"
On the inside of the open hooks is a spring-loaded flat bar that you
would press on with the rods as you slide the rods in. Once the rods are
in, you can lock a lever to secure them tight in place. However, even
before you lock the lever, the spring loaded bar will press up against
the rods, keeping them in place -- not securely but firmly enough to
keep the device from sliding off of the rods. (The lever is
repositionable. The looser you keep it, the weaker the flat bar will
Some 3/8" and 1/4" SYMPLA accessories that can be attached onto the
Universal Mount are the Flexible Mattebox, Shoulder Pad, V-Offset, Body
and Lens Supports and Adjustable Handles.
