Playfield and backbox glass sizes

Playfield glass must be tempered. Most WPC games take 21 x 43 x 3/16 inch. Wide-body games (Indiana Jones, Judge Dredd, Star Trek: The Next Generation, Popeye, Demolition Man, Road Show, Twilight Zone) take 23.75 x 43 x 3/16 inch; The small cabinets of Safe Cracker and Ticket Tac Toe take 3/16 inch glass measuring 36.5 by 18.5 inches. The translight cover glass is 18 7/8 x 27 inch (Safe Cracker 18 7/8 x 19 1/2), about 1/8 inch thick, and need not be tempered.
