5-meter electric ignitors that work with most remote firing systems. They are specifically made for consumer fireworks and clip right onto the fuse with a tight hold - no taping required! (Wiring Note: these are best run in parallel instead of series)
Fuse Connex are great for helping put your show together! These "X" shaped clamps tie multiple fuses together, and are designed so that the fuses pass fire without all the hassles of zip ties, tape, or other means of connecting fuses.
