Shock tube is a small diameter, three-layer plastic tube coated on the innermost wall with a reactive explosive compound. When initiated, shock tube propagates a low energy signal, similar to a dust explosion, at approximately 6,500 fps along the tube’s length with minimal disturbance to the outside of the tube.

The M81 igniter is used to ignite a cord that carries a detonation charge to initiate shock tube or time fuse blasting caps. To use, simply pull back the firing pin and the spring tension created forces the pin forward with enough force to set off the primer when the firing pin is released. The primer then ignites the cord, shock tube, or time fuse secured in the end of the igniter.
PULL FRICTION IGNITERS (CARDBOARD)
The Pull-Friction (Cardboard) type igniter is a non-electric, pull-string, friction style fuse igniter. This igniter functions by manually pulling a combustible mixture through a high-friction compression area, which ignites the combustible mixture, starting the fuse.
209 primers are used in various NONEL (non-electric blasting) initiators. They will work in mushroom starters, dual EOD starters, pen type, and various others.
