Rusan Q-R adapter M52x0.75 for Ø61 mm (ARM52-61)

The Rusan ARM52-61 adapter is an accessory intended to couple devices with an M52x0.75 thread to objectives or external barrels with a 61 mm external diameter. It is part of the ARM52 series and uses the conventional clamp adapter system to mount clip-on units and other threaded devices.

The ARM52-61 variant refers to the ARM52 series with a 61 mm external diameter. The device-side thread is M52 x 0.75, allowing attachment of equipment that uses that thread pitch. The product weight is 0.164 kg and it is classified as a "conventional" clamp adapter.

It is compatible with devices featuring an M52x0.75 thread. The ARM52-61 code explicitly identifies the 61 mm diameter version within the ARM52 family; other diameters are available as separate ARM52-<diameter> variants.

Orders must specify the ARM52-<diameter> code, so use ARM52-61 to request the 61 mm variant.
