25 lb Lead Ballast Weight with Mounting Holes – 2–4% Antimonial Lead

25 lb Lead Ballast Weight with Mounting Holes – 2–4% Antimonial Lead

Heavy-duty approximately 25 lb lead ballast and counterweight cast in the USA by Rock Shot Products. Made from 2–4% antimonial lead, this weight provides a compact, dense solution for applications where substantial weight is needed in a relatively small footprint.

Two approximately 1/2" diameter mounting holes, spaced approximately 8" center-to-center, make the weight easier to secure to a chassis, bracket, platform, equipment frame, or other suitable mounting location.

Why Antimonial Lead?

The addition of antimony produces a harder, more durable lead alloy than pure lead while retaining lead's high density and compact size. For ballast and counterweight applications where pure lead is not specifically required, this alloy provides an excellent combination of weight, durability and value.

Please Note: These are cast metal products. Surface texture, casting marks, discoloration, minor oxidation, dimensions and exact weight may vary slightly from piece to piece. These cosmetic variations are normal and do not affect their intended use.

Safety Notice: Lead and lead alloys can expose you to lead, which is known to cause serious health effects. Wash hands thoroughly after handling and keep away from children. Use appropriate precautions when drilling, cutting, grinding, melting or otherwise modifying lead products.
