47 - Rectangular Base Flange
Product Description
The Hollaender Speed-Rail® 47 – Rectangular Base Flange is a versatile mounting flange designed to provide a strong, stable attachment point for vertical pipes or posts. Its rectangular mounting plate offers increased surface contact and improved load distribution compared to round flanges, making it ideal for architectural, commercial, and industrial applications.
The slip-on barrel allows the pipe to be inserted directly into the flange and secured using zinc-plated set screws—no welding or threading required. Constructed from durable aluminum-magnesium alloy, the 47 Base Flange provides long-lasting corrosion resistance for both indoor and outdoor installations. Always verify the correct IPS pipe size before ordering.
