This 7lb. weight came with my Losmandy GM 8 mount, which I purchased second hand. It is machined, not cast. It has the proper resilient tip on the thumbscrew to prevent marring of the counterweight shaft surface. Since I already have two 7lb. weights, this one - the ugly one - has to go.
The dimensions are approximately 1.255 I.D. x 4.9 O.D. x 1.25 inches.
