Recovery Tethers & Line Cutters

A recovery tether is a simple device that allows you to use dual deployment out of the same opening in your rocket. We sell the Tinder Rocketry Tender Descender recovery tethers. Use the tether with a deployment bag to hold the main parachute inside your rocket until you want it to emerge. We feature three tether devices:

TD-2 Tether and Release Device - This strong tether can take a shock load of 2000 pounds and a steady state load of 1500 pounds. It activates with a few E-Matches or the J-Tek Initiator. Black powder or propellant is not needed.

Tether Protector Bag - When used inside a rocket airframe, we also sell a small Nomex bag to place your tether inside. This protects the airframe from the pin assembly when it releases (with some force) and, at the same time, prevents the hot gas from the black powder charge from damaging your recovery gear. Order a bag along with your tether if you plan to use this inside your airframe. Note that a protective layer is not required if using the TD-2 since the device is completely sealed.

Line Cutters - A line cutter is a very simple device that is used to cut a piece of nylon wire tie in order to allow your parachute to open or to release your parachute or anything else. It can also be used to reef a parachute.
