What the thread found

• The M2 top stage uses inch-standard threads (1/2-13), whereas most rod manufacturers supply metric threads (M12), causing many rods with internal threads to be incompatible.
• Tiffen M2–compatible 15 mm rods with 1/2-13 threads are supplied by Zacuto and Berkley Systems, with Berkley offering more length options.
• Tiffen manufactures matching rods directly but they are difficult to source online.
• Alignment problems attributed to rods may originate from the Tiffen monitor bracket itself not being perfectly square rather than from the rod.
• One operator reported that standard 15 mm rods fit the M1 model; checking the manufacturer's manual is advised before purchase.

Depends on

• Thread standard differs between Tiffen M2 and typical aftermarket rod suppliers.
• Alignment tolerance in the monitor bracket design.
