A candlepin bowling lane, almost identical to a tenpin bowling lane, has an approach area of for the player to bowl from, and then the lane proper, a maple surface approximately wide, bounded on either side by a gutter (or "channel", or trough.) The lane is separated from the approach by a "foul line" common to almost all bowling sports, which must not be crossed by players. At the far end of the lane are the pins, from the foul line to the center of the headpin (or pin #1), placed by a normally "manually"-triggered machine called a pinsetter which occupies space both above and behind the pins. Unlike a tenpin lane, which has a level surface all the way from the foul line end of the lane's approach to the back end of the lanebed's "pin deck", a candlepin lane has a hard-surfaced "pin plate" where the pins are set up, with the pin plate depressed below the lanebed forward of it. The pin plate can be made from hard-surfaced metal, "phenolic", "high density plastic", or a "synthetic" material. Behind the pin plate area of a candlepin lane is a well-depressed "pit" area for the felled pins and balls to fall into. A heavy rubber backstop, faced with a black curtain, catches the flying pins and balls so they may drop into the pit. Generally there is seating behind the approach area for teammates, spectators, and score keeping.
