# Overview and Features These FRC gear racks are designed to provide precise and controlled linear motion for your robot, an advantage over the sometimes unpredictable nature of pneumatics. They're made from lightweight yet robust 6061-T6 aluminum, coming in two tooth pitches (10DP and 20DP) to suit your gearing needs. And, at 35.5 inches each, you can stack them infinitely for extended travel distances!

**Notable Features** * Precise and controlled linear motion * 10DP and 20DP options * \#10-32 clearance holes * Infinite stacking * Can be stacked to increase gear face width --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
