45SBC - Square Base Flange
| Pipe Size: 1-1/2" IPS |
Product Description
The 45SBC – Square Base Flange is a heavy-duty base fitting designed to anchor a vertical pipe securely to a floor surface. Ideal for walkways, platforms, and areas requiring a sturdy post connection, this flange provides a strong square mounting footprint for pipe uprights. It is especially useful in applications requiring ADA-compliant handrail installations
Constructed from high-strength aluminum-magnesium alloy 535, the 45SBC – Square Base Flange offers excellent corrosion resistance and long-term durability in both indoor and outdoor environments. The fitting slides over standard IPS pipe and is secured with two zinc-plated set screws, creating a rigid mechanical connection without welding or threading. Always verify pipe size and choose appropriate anchors based on substrate and loading requirements.
