This handy 4 or 1 igniter connector allows you to plug into certain firing systems, at least cutting the "squibbing" time by 1/3. Think of the time this will save you in the heat/cold, or when a show prep time is running late. Each match color coded to know which cues you are connected to.
4 group igniters, add 0.36 to the igniter cost.
Single igniters, add 0.09 each for the quick connect
