Long, fine, uniform strands of chemical grade lead are used in the manufacture of Lead Wool, which is then twisted into 5/8” rope for use in lead shielding and caulking. Certified to meet Federal Specification QQC-40. Lead Wool is preferred for caulking joints because it requires no heat and does not contract upon cooling as does a poured joint.
Available in 5 lb. boxes, packed 50 lbs. per carton.
