The KPC-A1403 90° Elbow is an A535 aluminum-magnesium alloy slip-on pipe clamp for 42.40 mm (1.66") outside diameter tube. It forms a sharp right-angle corner between two pipes, 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
A square corner is still the backbone of many frames. This alloy elbow keeps that corner lighter, polished, and corrosion resistant.
Key Features
90° elbow geometry creates a crisp corner for pipe frames and display structures.
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 stage deck frames, shop displays, pipe-and-drape corners, exhibition builds, restaurant fit-outs, guardrails, and lightweight outdoor-friendly tubular structures.
Compatibility
Fits 42.40 mm (1.66") outside diameter tube for Schedule 40 nominal pipe. The related KPC-A1203 version fits the companion tube size in the same KPC-A family.
Frequently Asked Questions
Is this part of the aluminum-magnesium clamp family?
Yes. It is an A535 aluminum-magnesium alloy slip-on fitting, not one of the cast-iron KPC pipe clamps.
Why choose the alloy elbow over an iron clamp?
The A535 aluminum-magnesium alloy body is lighter and corrosion resistant, which helps on visual builds and environments where weight matters.
Which tube size does this version fit?
This version fits 42.40 mm (1.66") outside diameter tube. Check the sister model if your structure uses the companion KPC-A tube size.
