Issue:
In which orientation are the isolators placed underneath base rail?
Resolution
- Isolators should be oriented with the widest side perpendicular to the base rail in order for the mounting slots to be accessible.
- Secure the isolators to the mounting surface using the mounting slots in the isolator base plate. Do not fully tighten the isolator mounting bolts at this time.
- Align the mounting holes in the base of the unit with the threaded positioning pins on the top of the isolators.
- Lower the unit on to the isolators and secure the isolators to the unit with a nut.
- Level the unit within a 1/4" length and width (refer to submittal and IOM)
- Fully tighten the isolator mounting bolt.
The "ears" of the isolators that stick out past the rail will have a metal plate inside the rubber to allow for the bolts to tighten.
For installations where the "ears" will be floating over the edge of a rail/beam, a metal plate could be welded to the beam to support the entire isolator.
