FS Sleeve Length Update

F/S Sleeve Length is Changing in January

We are changing our F/S damper sleeve lengths from standard 16” long to 20” long. The longer length helps to reduce the number of units where we must install the Electronic Fuse Link (EFL) on the side opposite the actuator, which requires that you have access to both sides of the damper when installing the unit in the field.

This improvement will allow us to mount the EFL on the same side as the actuator for more units, which will save you time and money when installing our dampers.


Current and New Arrangement

Coming soon – our new Red Button EFL. Contractors will love the new features!
