46AHD - Heavy Duty Adjustable Base Flange
| Material/Finish: Aluminum Magnesium |
Product Description
The Hollaender Speed-Rail® 46AHD – Heavy Duty Adjustable Base Flange is a reinforced, high-strength mounting flange designed for floor or platform installations where the connected pipe must be set at a variable angle. Unlike fixed-angle base flanges, the 46AHD features an adjustable slip-on barrel, allowing the post or rail to be aligned precisely to match slopes, ramps, or non-standard layout conditions.
Its heavy-duty construction provides increased load capacity compared with standard adjustable flanges, making it suitable for structural or high-traffic installations. The pipe is secured using zinc-plated set screws, eliminating the need for welding or threading. Constructed from corrosion-resistant aluminum-magnesium alloy, the 46AHD delivers long-term durability for indoor and outdoor environments. Always verify the correct IPS pipe size before ordering.
