It is differs from multiple [[spark gap]]s in that a spark strip is mounted using two or even one [http://www.advancedspuds.com/his.htm (temp link)] hole.

	A spark strip consists of several conductive objects in a row with a short gap in between, effectively forming a line of spark gaps. As with other spark gaps, the combined width of the gaps must be small enough for the [[ignition source]] to overcome.

			Spark strips are sometimes seen as inferior to a screw based gap system, because they are often mounted on the wall of the chamber, as opposed to screws, where the spark is in the very centre of the chamber. This means that the flame from can only travel in one direction (away from the wall). A central gap allows the flame fron to spread in every direction towards the walls.
