Cut it once.
Cut it right.

Tube notching — also called coping or fishmouthing — is cutting the end of one tube so it hugs the curve of another tube. The result is a tight saddle joint that welds up strong with no gaps. It's the joint behind every roll cage, go-kart frame, off-road bumper, and exhaust system. Our tube notching templates give you the exact cut line: print, wrap, trace, cut.

A fishmouth (or fish mouth) cut is the curved, open-mouth shape cut into the end of a tube so it saddles over another tube — the same thing as a saddle cut or cope. Cutting that curve freehand is guesswork. A fishmouth template draws the exact curve for your tube size, so the joint fits the first time.

Every PunchMapPro PDF is drawn to true 100% scale. In your print dialog, set scaling to 100% / Actual size — turn OFF "fit to page" or "shrink to fit." Each template includes a check square: measure it after printing. If the square measures exactly right, your printable template is exact and ready to wrap around the tube.

Tube coping (pipe coping) cuts a curved saddle so one tube wraps the outside of another — the classic T-joint or fishmouth. Mitering cuts a straight angle across the tube end so two tubes meet at an angle, like bumper corners. Our coping and miter templates handle the curves and the angles — every common size is a print-ready sheet.

One payment of $1 unlocks every template on the site — forever. After checkout you land in your Library with everything ready to download. No subscription, no renewals.

Roll cages, go-kart frames, off-road bumpers and rock sliders, exhaust systems, handrails, shop furniture — anything built from round tube or pipe. If the job needs two tubes to meet clean, there's a printable template for it in the catalog above.
