Crossarm
Crossarm Pins are forged in one piece from alloy steel with large bases to distribute loads without crushing flat wood crossarms. A square wrenching shoulder is provided above the base for rotating the insulator groove into position.
Long shank pins come complete with a square washer, square nut and concave MF locknut. Short shank pins for steel crossarms are furnished with a square nut and split coil lockwasher.
Material:
- Pin: Forged Steel
