The KPC-A1246 Railing Base Flange is an A535 aluminum-magnesium alloy slip-on pipe clamp for 48.30 mm (1.90") outside diameter tube. It anchors a vertical pipe to a deck or step for handrail and guardrail applications, using 3/8" galvanized steel recessed grub screws with reverse knurled cup points for a no-weld structure that installs with a standard hex key.
Why It Matters
Railing posts need a base that reads as part of the rail system, not just a generic pipe mount. This flange is shaped around that handrail and guardrail use case.
Key Features
Specialized railing base flange anchors vertical pipe for handrail and guardrail work.
A535 aluminum-magnesium alloy keeps the fitting lightweight and corrosion resistant for outdoor or harsh environments.
3/8" galvanized steel recessed grub screws with reverse knurled cup points hold the pipe securely.
Standard hex-key installation avoids welding, specialist labor, and permanent fabrication.
Additional Technical Notes
Set Screws: 3/8" galvanized steel recessed grub screw with reverse knurled cup point
Applications
Use for railing posts, guardrail bases, deck or step-mounted pipe, access routes, recreational venues, exhibition structures, and outdoor-friendly handrail systems.
