Perform Length Adjustments (Inner Envelope Openers)

inner envelope opener.

adjustments only. But, when needed, these (except the Middle Opener) can
be moved laterally.

Thumbscrews
a. Position the inner envelope openers so they do not touch the edge
of the window. In unusual circumstances, i.e., vertical windows, it
may be necessary to place the opener on the window to prevent the
opener from catching on the window's edge.
b. Tighten the thumbscrews for the adjusted openers.
2. Press down then pull one of the knobs on the top of the frame to deter-
mine how far the insertion edge of one inner envelope opener, goes into
the envelope.
3. If necessary, loosen the knob on the insertion edge of the Inner
envelope opener, and adjust until it goes at least 5 mm into the top panel
of the envelope.
