Makes a 11 1/4 degree turn, 32 would be needed for a full circle, but don't use these for a full circle - 8 regular (6-12015) curved will do the job. See diagrams for use of the 1/4 curve - usually used to complete the turn of a 36 inch switch from 33 3/4 degrees to 45 degrees. Fastrack for Lionel Trains.
