While each type of Altimeter are mounted slightly differently, they should all be mounted with screws and spacers, or standoffs. To get the correct hole pattern on the mounting rack, place the altimeter on the mounting rack in the correct position, mark where the screw holes in the altimeter PCB are, and drill them out. The holes should be sized such that the screws you are using can thread into the duron. Make sure that you use spacers, as shown in the diagram, between the altimeter and the mounting rack. Otherwise, the barometer may be pressed against the duron and not take accurate readings.
