The Clamp Type Crossarm Pin installs around the crossarm using a wide base that distributes mechanical loads and eliminates the need for pre-drilled holes. This approach ensures secure attachment without compromising wood or fiberglass crossarm integrity, enabling straightforward assembly in utility and electrical distribution applications.
The pin body uses hot dip galvanized steel for corrosion resistance and environmental durability. Insulator threads are manufactured from a nylon alloy compound (Joslyn Engineered Material) that delivers consistent performance under electrical and mechanical stress, supporting long-term reliability in outdoor and high-load conditions.
The forged pin body is welded to a wide base saddle for enhanced structural integrity and load distribution. Nylon insulator threads are permanently molded to the pin body and meet 1-inch American National Standards Institute (ANSI) standards for compatibility with pin-type insulators. A square wrenching shoulder above the base enables precise rotation and positioning of the insulator groove.
The assembly includes carriage bolts and a clamping plate with raised projections to resist movement; the clamp plate can be reversed for fiberglass crossarms. Depending on shank length, the pin includes either a split coil lockwasher and square nut, or a square washer, square nut, and MF concave lockwasher for secure fastening and vibration resistance.

Frequently Asked Questions (FAQS)
What is a clamp type crossarm pin?
RaxPower's clamp type crossarm pin is designed to encircle the crossarm with a broad base that distributes the load and eliminates the need for drilled crossarm holes.
How do your clamp type crossarm pins ensure long-term reliability and compliance with industry standards?
Our crossarm pins are forged in one piece from alloy steel and hot dip galvanized, with ANSI standard nylon alloy threads, ensuring durability and adherence to industry standards for electrical safety and grid reliability.
What makes your crossarm pins durable enough for high-stress environments like railway electrification?
The forged pin body with large bases distributes loads without crushing, and the hot dip galvanized steel construction resists corrosion, making them suitable for high-vibration and demanding conditions.
Can your crossarm pins be used on both wood and fiberglass crossarms?
Yes, the clamping plate can be reversed to accommodate fiberglass arms, providing versatility for different crossarm materials used in telecommunications and power applications.
Do your crossarm pins come with all necessary hardware for installation?
Yes, they are furnished with two 5/8 x 7
How are the insulator threads designed?
The insulator threads are permanently molded to the pin body using nylon alloy, conform to 1
Are different shank lengths available?
Yes, RaxPower offers both long shank and short shank pins; long shank pins are supplied with a square washer, square nut, and MF concave lockwasher, while short shank pins come with a split coil lockwasher and square nut.
