Tube Marking Guide

The Estes Tube Marking Guide gives students a simple, reliable way to mark fin and launch lug placement lines on model rocket body tubes. By creating clear reference points before assembly, students can work more accurately and develop stronger building habits.

Build Alignment and Measurement Skills

Using the guide encourages students to think carefully about spacing, symmetry, and component placement. These hands-on steps reinforce practical STEM concepts while helping learners understand how precise construction can affect rocket stability and flight performance.

Includes a Helpful Fin Gluing Jig

The included fin gluing jig helps students keep fins positioned correctly while adhesive sets. This added support can make group activities easier to manage and gives learners more confidence as they complete one of the most important stages of rocket construction.

Made for Classrooms and Youth Programs

Reusable and easy to incorporate into model rocket activities, the Tube Marking Guide is a valuable addition to classroom supply kits, STEM labs, camps, clubs, and youth organizations. It helps educators guide students toward cleaner builds while encouraging patience, precision, and problem-solving.
