No. Cables per Port
With or without
cable attachment
IMPORTANT: Store unused components and installation
instructions in bag and keep inside closure for future cable ter-
minations. If these parts are lost, you will need to order the
above 450 B/Gel cable kit to terminate future cables.
3.0 Open Closure
Note: Before opening a sealed closure make sure all air is bled
from the closure, use the valve in the dome to do this.
1. Remove the dome to base clamp. Pull the clamp slightly to the
side and lift the clamp handle, use the feet of the clamp to pry
against the two posts to spread the clamp open. Open one side of
the clamp all the way and pull it back on itself quickly to remove it
from the dome and base (Fig. 1).
2. Remove the dome from the base of the closure.
Note: Using a FOSC ACC 450 closure workstand makes
installations easier (PML #941802-000).
3. If a gel seal is already installed loosen the gel seal by turning the
tail of the seal counter-clockwise until the seal is loose. Unsnap each
of the two wire clips and remove the base from the metal frame.

4.0 Cable Preparation
Note: The maximum slack storage lengths listed in the chart
at right will be limited more with higher count Loose Buffer
Tube (LBT).
Note: Cable range is .35" to 1" diameter.
IMPORTANT: Small round or flat cable installations -- If cables
are less than 0.35” in diameter or flat drop style, an additional
step is required for cable sealing in the port. In this case the
cable diameter must be build up to the minimum 0.35” diame-
ter. In addition, if multiple small cables like these are to be
installed in a single port, it is imperative that gel is applied
between the cables before installing them into the gel port.

tions or FOSC 450 Single Small Cable Kit installation instruc-
tions for further details.
