Descripción

Our Poly Closure Cap Plug provides a professional and reliable seal for unused 1-1/2" NPS openings in traffic signal heads and mounting hardware. Designed to protect the internal components of your signal assembly, these plugs prevent water, dust, and nesting insects from entering the housing, ensuring long-term operational reliability.

Molded from high-impact, UV-stabilized polycarbonate or polyethylene, these caps are built to withstand years of exposure to sunlight and extreme weather without becoming brittle or fading. They are a cost-effective, corrosion-proof alternative to metal closure caps.

Key Features

  • Weather-Tight Seal: Designed to provide a secure fit that keeps moisture and debris out of signal housings and bracket arms.
  • UV-Stabilized Material: Engineered from high-grade polymers that resist degradation and "chalking" caused by prolonged sun exposure.
  • Standard Compatibility: Features 1-1/2" NPS threads, making it compatible with all standard traffic signal heads including Pelco, McCain, Econolite, and Eagle.
  • Corrosion-Proof: Unlike aluminum or iron caps, these poly plugs will never rust or seize, making them easy to remove for future maintenance.
  • Easy Installation: Designed with a standard "coin slot" or hex-head top for quick installation and removal using common tools.

Application & Maintenance

These closure caps are essential for maintaining the integrity of traffic signal systems in the following scenarios:

  • Capping Unused Openings: Seal top or bottom holes when a signal is mounted via a side-arm or bracket.
  • System Upgrades: Plug holes left behind when moving or removing signal sections or hardware.
  • Hardware Protection: Prevent "wasp nesting" inside mounting pipes and signal bodies, which can damage wiring, components and pose a safety threat to service personnel.
