Product Description
Insulation-piercing clamps are critical components for installing fiber-optic communication lines and are widely used in telecommunications networks, rural broadband initiatives, and energy projects; they enable the connection of ADSS (All-Dielectric Self-Supporting) cables to support structures.
Featuring a self-adjusting clamping mechanism and high-performance plastic inserts, the clamp securely grips the cable bundle while preventing damage to the optical fibers. The main body is constructed from an aluminum alloy that combines lightweight properties with superior mechanical strength, while the integrated stainless steel bracket offers excellent corrosion resistance, making it suitable for mounting on hooks or poles in coastal and salt-spray environments.


The clamp boasts outstanding UV resistance, withstanding intense sunlight and harsh outdoor conditions without aging or cracking; it is designed for easy installation, allowing for rapid assembly without the need for complex tools.
Its reliable fastening system ensures stable tensile strength, maintaining the cable's position even when subjected to wind loads, temperature fluctuations, and tensile stress.
JASCO offers a variety of anchoring clamp models to accommodate different types of fiber-optic cables.
As a professional supplier of fiber-optic products, JASCO delivers consistent quality and supports OEM customization services.
