The TR-18D Stack Separator is a Separator that allows for staging rockets vertically and in sequence.


The TR-18D adds a stage to the rocket and when activated will release the separator as well as anything attached to it, much like the TR-2C. Unlike normal decouplers, separators come free from both sides, leaving the decoupler floating.

Product description

The TR-18D StackSeparator was originally designed as an explosive cutting tool. After deciding cutting a rocket in half, just had to be a good thing, our designers set to work adapting the technique to rockets.
