Everything from the title

One kilogram, stainless steel, 20.5 mm internal diameter, for equatorial mounts. There are no bullet points, so that is the complete specification.

The bore is the right figure to publish

Twenty point five millimetres, which slides onto the common 20 mm shaft with half a millimetre of clearance. That is the number most counterweight listings omit and the one that decides whether the part is usable at all.

Stainless steel

More corrosion-resistant than a painted cast weight, which matters for something that sits outside in the damp and gets knocked against a tripod leg. It is also denser than cast iron for the same mass.

What goes undescribed

How it locks. A counterweight that can slide is dangerous when a clutch is released and useless for balance. Every weight needs a positive screw, and this listing does not mention one.
