How are I-Line blank extensions installed?

Used on HCW, HCP, HCWM and HCR-U interiors:

If a branch breaker, 400 amp frame or larger, is being replaced with a smaller frame breaker, a blank extension is required to fill in the gap left by the larger breaker.
If a branch breaker, 400 amp frame or larger, is removed and is not replaced with another breaker. a blank extension is used in combination with a blank filler to fill the space.
The blank extension snaps into place against the deadfront with its smooth side towards the breaker/filler.
