A stabilizer is used to provide tighter coupling of disc to the turntable. It's even more so for slightly warped records. 

As we know disc stabilizers come in many forms and shapes in addition to different materials. And for this disc stabiliser, other than the weight (lower section) is of stainless steel, the handle is made of light weight alloy. It's designed so to reduce the weight in the inner segment which would improve the moment of inertia when the platter turns, without adding unnecessary extra burden to the main bearing. 

It is able to accommodate top spindle height of up to 25mm(~1") and will not damage the stylus in the event that the cartridge knock against the stabilizer weight when the needle runs over the record label.
