Line Hardware Inc. was organized in 1970 to produce custom and standard line products in steel and iron for the electric utility industry. In time, products made of copper, bronze and aluminum were added to the line as well as hardware designed for telephone systems. Today, Line Hardware seeks to serve its customers with well designed and tested products which meet the ever changing needs of the line construction industry.

Tests of LHI products are performed at state of the art, independent testing laboratories.

To insure quality finished products we start with quality raw material and use the best, most practical, manufacturing processes available. Ferrous castings are made of ductile iron, grade 654512, which provides higher strength and greater elongation than other cast irons. Steel products are made of domestically sourced hot rolled steel, typically A-36. Bronze and aluminum alloy products are made of the grade most suitable for the product, considering the electrical conductivity, strength and machinability required. Copper products are made of C110 Copper Electrolytic Tough Pitch.

All product weights and standard packaging information are contained in the Weight and Packaging Guide that accompanies this catalog. All weights listed are packed weights. LHI products are packaged in durable cartons and palletized. To ease handling, standard packages are kept under 60 lbs.. and pallet weights do not exceed 3,000 Lbs.. Each carton is clearly labeled with product catalog number, description, quantity and weight. Your special packaging requirements should be indicated when request for quotation is made and when placing orders.

Hot dip galvanizing is the industry accepted solution to corrosion of ferrous line hardware. The products of LHI are galvanized in accordance with the latest revision of the ASTM A-153 standard for zinc coated steel and iron hardware. After fabrication, each part goes through a ten step process in modern galvanizing facilities to provide the best possible finish. A visual inspection of the cooled parts is performed to ensure complete coverage. Random testing with a hand held magnagauge is performed to check for proper mil thickness.

We keep many of the commonly used line, hardware products in stock. This enables us to meet the occasional critical needs of our customers. Items quoted as “in stock” are subject to prior sale and may not be available when ordered. Not shown in this catalog are the many custom products made to meet the special requirements of our customers. We are prepared to make these items when there is adequate quantity to justify tooling and production expense. Please contact us regarding your special material need.
