Charge Released Locking Mechanism
Tether is a small but
strong retaining device released by a reloadable pyrotechnic charge.
Tether is machined from 7075 aluminum with all stainless steel components.
Tether only weighs 1.7 ounces prepped, fits in a 38mm airframe, and is able
to hold and release under 500 pounds of load.
Tether has many uses, but its most popular use is to achieve two-stage recovery
with one compartment.
You can modify any existing altimeter-controlled rocket, without structural
modification, to take advantage of drogue-at-apogee/low-altitude-main deployment,
on the range and in just minutes.
Tether was the 2001 winner of WildHobbies.com
Reader Choice Award for Rocketry Innovation of the Year.
Tether is manufactured in the United States of America.
