“Tenon Adaptor for Square Pole M” with the given UPC code “6505925386122” up until my last knowledge update in September 2021. It’s possible that this product was introduced or updated after that date.
A Tenon Adaptor is typically used to mount fixtures or equipment designed for round poles onto square poles. It allows for a secure and stable installation. The “4”” likely refers to the size of the square pole the adaptor is designed for.
If this is a real product, I recommend checking with local hardware stores, online retailers, or the manufacturer directly to obtain the most up-to-date information, availability, and specifications.
