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. Adding only .16 per igniter, this cost is quickly absorbed in labor and installation time. Please call to add these to your igniter order.
