The KPC-A1211E Corner is part of KUPO's A535 aluminum-magnesium alloy slip-on pipe clamp family for 48.30 mm outside diameter tube. It forms an interior 90° corner for mitered railing and frame joints, using 3/8" galvanized steel recessed grub screws with reverse knurled cup points for a no-weld pipe structure that can be installed with a standard hex key.
Why It Matters
Interior corners often need a neat visual transition as much as a mechanical connection. This alloy corner fitting keeps mitered pipe work clean and corrosion resistant.
Key Features
Interior 90° corner fitting supports mitered joints in railing and frame applications.
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
