This Qualman Rocketry BT70 Model Rocket Divider keeps your parachute, shock cord and wadding near the top of the rocket. Also, includes a built-in Kevlar shock cord mount that is further away from the ejection charge in comparison with connecting the Kevlar shock cord to the engine mount. This durable divider is precision laser cut from 1/8 inch thick lite ply. A divider is used with recovery wadding or a Nomex cloth (not meant to replace a baffle). Fits inside a BT70 size body tube.
