Overview

A CAP dumbbell from the SDRSIS-150R line, model coded 24DB, built from carbon steel and weighing 23.14 pounds, meant to fill out a fixed-weight home gym rack.

The 150R in the model name points to this piece belonging to a larger fixed-weight dumbbell line that runs up to 150 pounds, with the 24DB code marking this specific weight. Carbon steel construction favors durability over the softer feel of a rubber or urethane coating.
