The crossarm insulator pin supports pin type insulators on crossarms in electrical distribution systems. It features internal threads compatible with National Electrical Manufacturers Association (NEMA) standards, such as 1-inch or 1-3/8-inch sizes, to securely hold insulators in place.
Constructed from galvanized steel complying with American Society for Testing and Materials (ASTM) A-153 specifications, the pin includes nylon threads that eliminate handling and disposal concerns associated with alternative materials. The nylon threads meet all American National Standards Institute (ANSI) performance and dimensional requirements, providing a firm yet resilient fit. These threads are more impact resistant than lead alternatives, enhancing durability in various environmental conditions.
The forged design incorporates flats for wrench engagement and a wide base to optimize load stress distribution across the crossarm. In clamp type variants, the clamping design requires no cutting or drilling of the crossarm, and the back plate features raised projections to prevent slippage during installation and use. Specifications include a threaded area length of 3 units and a weight of approximately 4.65 pounds, with options for different NEMA thread sizes to accommodate various insulator types.
Each pin is shipped with all necessary galvanized steel hardware assembled and ready for installation in straight line, angle, or corner construction applications.

Frequently Asked Questions (FAQS)
How do you ensure that your crossarm insulator pins meet industry standards for reliability and safety?
RaxPower's insulator pins are hot-dip galvanized per ISO 1461 standards, with a mean coating thickness exceeding 85 microns. They are constructed from steel with a galvanized coating that complies with ASTM A-153, ensuring durability and corrosion resistance. All pins meet ANSI performance and dimensional requirements for guaranteed compliance.
What are the benefits of nylon threads on insulator pins?
Nylon threads eliminate handling and disposal concerns associated with lead threads, provide a firm yet resilient insulator fit, are more impact resistant, and meet all ANSI performance and dimensional requirements, making them a safer and more sustainable choice.
Can the Crossarm Insulator Pin be used for different construction types?
Yes, clamp type crossarm pins (saddle pins) from RaxPower can be used for straight line, angle, or corner construction without the need for cutting or drilling the crossarm. The back plate has raised projections to prevent slippage, ensuring a secure and stable attachment. They are shipped with all necessary hardware assembled, simplifying installation.
What features contribute to the durability and strength of your insulator pins?
Our pins feature a forged design with a wide base to distribute load stresses and flats for wrench engagement, ensuring greater strength and accurate sizing. This manufacturing process enhances product longevity.
What thread sizes are available for the Crossarm Insulator Pin?
The RaxPower Crossarm Insulator Pin supports pin type insulators with 1 NEMA internal thread or 1-3/8 NEMA internal thread on the crossarm.
What is the weight of the Crossarm Insulator Pin?
The weight is approximately 4.65 pounds for certain models, as specified in the product details.
