Power tool guide rail
Accessory to a power tool, such as a straight, swivel or angle jig for a circular saw, and can also be referred to as a fence. The guide rail system provides an acute method of cutting material.Elevator shaft guide rail
Guide rails are part of the inner workings of most elevator and lift shafts, functioning as the vertical, internal track. The guide rails are fixed to two sides of the shaft; one guides the elevator car and the other for the counterweight. In tandem, these rails operate both as stabilization within the shaft during routine use and as a safety system in case of emergency stops.Roadway guide rail

According to the US Federal Highway Administration, the terms guardrail and guiderail are synonymous.Several types of roadway guide rail exist; all are engineered to guide vehicular traffic on roads or bridges.
