90 Degree Tube Notch - 1.5" Diameter x .083 Wall - DOM 1020

A 90-degree saddle cope for 1.5" OD DOM 1020 tube with .083" wall thickness — one of the most common specs in roll cage and chassis fabrication. Open this project to see the full cope geometry, then generate and print a full-scale template to wrap around your tube as a cut guide. DOM 1020 is a drawn-over-mandrel mild steel with tight tolerances, making it a go-to for structural tube work where consistent wall thickness matters for welding. The 90-degree intersection is the most common coped joint in fabrication, showing up in handrails, frame rails, cage uprights, and crossmembers.
