Can you make Assembly Fixtures for rail other than Micro Engineering?

While we encourage our customers to use Micro Engineering rail to build switches in our assembly fixtures, our fixtures are compatible with rail produced by other manufacturers. Rail produced by many manufacturers is actually 100% compatible with Micro Engineering rail and can be used in a fixture cut for Micro Engineering. Below is a table of rail dimensions for various other makes of rail.

How We Measured The Rail

All rail samples were measured using digital calipers or a micrometer and are accurate to within +/-.001".

Measurements were taken from sample rail pieces that we have on hand. All Micro Engineering samples are available as individual length of rail. All other sizes were removed from flextrack.
