This square-to-round tenon adaptor from CSC LED is precision-engineered to provide a secure and stable transition between square pole tops and round tenon-accepting fixture mounts. Constructed from heavy-duty, corrosion-resistant materials, the adaptor is designed to endure harsh weather conditions — including the freezing temperatures, ice, and moisture common across Canadian climates. Its robust build quality ensures long-term structural integrity, keeping your mounted fixture safely in place through every season.

The adaptor is cUL listed and CSA approved, meeting all relevant Canadian electrical and structural safety standards for outdoor mounting hardware. This certification gives homeowners confidence that the product has been rigorously tested and is fully compliant for residential and general outdoor use. When paired with compatible CSC LED fixtures and FL-series mounts, it forms part of a complete, standards-compliant lighting assembly that meets or exceeds local code requirements.

Installation is straightforward and designed with the DIY-friendly homeowner in mind. The adaptor seats securely onto compatible square pole tops and provides a standard round tenon output for slip-fitter-style fixture bases. No specialized tools or professional expertise are typically required — just basic hardware and a few minutes of setup time. This makes it an ideal solution for property owners looking to retrofit existing poles with modern LED area lights, flood lights, or post-top fixtures without undertaking a full infrastructure replacement.

By enabling easy fixture upgrades, this adaptor plays a key role in helping homeowners transition to energy-efficient LED technology. Rather than leaving an outdated pole unused or investing in costly new installations, you can simply adapt what you already have and mount a modern, high-performance LED fixture on top. It's a practical, cost-effective approach to improving your property's outdoor lighting performance and curb appeal.
