The Derby Magic timers have a standard spacing of 3 and 7/8″ lane spacing. If you have a track or need a timer that fits a different lane spacing, we are able to accommodate to your request.
The information that we need to be able to make the timer fit your track are as follows:
1) Width of the track.
2) Distance from one side of the track to the center of each lane.
3) The overall length of the track from the start gate to the timer.
When you order a custom timer, you will receive a start switch that will mount to your start gate to start the timer upon race start. Here are the dimension so that you can make sure you can mount it to your track frame.
