Original electrical trade vintage catalog for SEYLER MANUFACTURING COMPANY, was located at Butler Plane Road, Pittsburgh, PA. Manufacturers of pole line construction specialties include anchoring materials, guying, pole fittings, grounding equipment, bolts and screws, braces, brackets, clamps and hardware. Shown are Thimbleys anchor rod, bonding clamp, ground rod, pie expansion bolt and more. Disbound from a large 1944 electrical construction materials book, this unique old two page technical specifications brochure would display wonderfully matted and framed. A marvelous addition to your retro electric equipment library. Contains a small amount of residual glue on edge.
