Heater Vent

[redek]

I just received a new heater vent to replace my broken one. I pulled the spring out of the vent, but am not sure how to replace it. Do I thread the spring through the vent, or am I missing a clip that goes through the hole.
Thanks,
Derek

You're talking about the circular vents?

The "wire" (spring) goes into holes on the vent. You kind of bend the wire slightly and it will go in easily, then the springing action of the wire yanks the vent down and into place.
