The SEC-5B Ejection Canisters feature a snap-top ejection charge container that holds 1.5 grams of black powder or smokeless powder. The single-use Ejection Canisters are convenient and reliable methods of deploying your recovery system.

XLEjection Canisters are for rockets with more volume to pressurize than can be done by our smaller canisters. Each Ejection Canister is tested for continuity before being packaged. Variable capacity allows you to determine how much propellant you wish to use for your particular recovery system.

Compact Ejection Canisters are designed for smaller models that use electronic ejection, but have a diameter that is too small for our SEC-5 Standard canisters. They are slim enough to fit into 13mm body tubes. CEC-5 canisters come packaged in tamper-proof ziplock bags of 5.

Large Ejection Canisters are about half again as big as the standard SEC-5a Ejection Canisters. They hold about 2.5 grams of black powder (not included). They are suitable for rockets of 4 to 5.5 inches in diameter. Each Canister has the resistance written on the side, so you can test it before use.
