29mm Model Rocket Motor Retainer Set

Easy to install and easy to use. This is a good retainer for the price and an excellent alternative to the more expensive metal retainers which can cost as much or more than the rocket they are used on. After a few launches of E-G class motors, my first pair are holding up well. My only nit is that it is a bit bulky. On smaller diameter rockets, the closure is larger than the rocket. On one use, I sanded down the ribs to make the model a bit more aerodynamic. I just bought two more packs and plan to use these on all my 29mm motor mounts.
