The KPC-A1409 3 Way 90° is an A535 aluminum-magnesium alloy slip-on pipe clamp for 42.40 mm (1.66") outside diameter tube. It connects three pipes meeting at right angles for cube-frame corners, 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 cube corner defines the whole display case or frame. This fitting keeps three axes square in a lighter alloy body with a polished corrosion-resistant finish.
Key Features
Three-way right-angle body connects three pipes at a cube or display-case corner.
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
