Product Description

Overview

The KPC-A1446 Railing Base Flange is an A535 aluminum-magnesium alloy slip-on pipe clamp for 42.40 mm (1.66") outside diameter tube. It anchors a vertical tube 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 a generic pipe mount. This flange is shaped around that handrail and guardrail use case.

Key Features

  • Specialized railing base flange anchors vertical tube 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 tube 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
