24 mm Motor Retainer Set

The Estes 24 mm Motor Retainer Set gives educators and program leaders a simple way to improve motor installation during model rocket activities. Its threaded design securely holds compatible motors while making it easier to prepare rockets for launch and remove used motors afterward.

Simplify Launch Day Preparation

Efficient motor changes can help keep classroom demonstrations, club launches, and camp activities moving on schedule. Students can spend less time struggling with motor retention and more time observing flight performance, reviewing results, and preparing for the next launch.

Built for Repeated Educational Use

The retainer set is molded from heat-resistant ABS plastic for lightweight strength and lasting durability. Its reusable construction makes it a practical component for programs that conduct multiple builds or launch sessions throughout the year.

Support Hands-On Rocket Design

This 24 mm Motor Retainer Set is well suited for custom rocket projects that introduce students to motor mounts, propulsion systems, and component selection. Compatible with Estes C11, D12, and E12 motors, it gives learners a reliable retention solution as they apply engineering concepts to a working model rocket.
