◆ Designed in international standards: ASTM A-153, ANSI C29.5, ANSI C29.6,
◆ Materials: ANSI standard nylon alloy or cast lead threads for pin type insulators
◆ Body: steel hot dip galvanized
◆ Large bases distribute loads without crushing flat wood crossarms.
◆ Long shank pins come complete with a square washer, square nut and concave locknut
◆ A square wrenching shoulder is provided above the base for rotating the insulator groove into position
◆ Short shank pins for steel crossarms are furnished with a square nut and split coil lockwasher
