Preparing the Table and Cable Cubby 1252 MS Lid
Prepare the lid and cut a hole in the surface where the enclosure will be installed. Read the following information before making a
cut.
Determine the best location for the enclosure
Ensure that the location where the Cable Cubby 1252 MS is to be installed is convenient for as many users as possible.
Ensure that the edge on which the lid opens is oriented correctly.
Ensure that there is ample space under the table for cables. Allow at least 36 inches of cable loop for each cable (see
Routing and Connecting Cables on page 10).
When installing retractors in the Cable Cubby, ensure that there is enough space for the retractor assembly under the table or
furniture (see the Dimensions with a Retractor on page 11 for retractor dimensions).
Prepare the table
ATTENTION:
• The correct dimensions for the cut in the table surface depend on the thickness of your lid material.
• If the total lid thickness is equal to or thicker than the table surface, see figure 1 on page 3.
• If total lid thickness is thinner than the table surface, see figure 2 on page 3.
• Les dimensions correctes pour la découpe dans la surface de table dépendent de l’épaisseur de votre couvercle :
• Si l’épaisseur totale du couvercle est égale ou plus importante que la surface de la table, regardez la
figure 1.
• Si l’épaisseur totale du couvercle est moins importante que la surface de la table, regardez la
figure 2.
• For a professionally-installed appearance, the mounting surface for the Cable Cubby 1252 MS requires precise cuts.
Extron strongly recommends cutting the hole via a computer numerical control (CNC) machine only.
• Pour offrir un design professionnel, il est nécessaire de couper avec précision la surface de montage du
Cable Cubby 1252 MS. Extron recommande vivement de percer le trou uniquement à l’aide d’une machine-outil à
commande numérique.
• The opening in the table for the Cable Cubby should be cut only by licensed and bonded craftspeople. Exercise care to
prevent scarring or damaging the furniture.
• L’ouverture dans la table pour le Cable Cubby doit être coupée uniquement par un ouvrier détenteur d’une licence.
Veillez à ne pas laisser de marques ni à détériorer le mobilier.

1. Cut a hole in the table for the Cable Cubby 1252 MS. See the table below to determine:
• The location and orientation of the cut on the table
• The correct size of the cut, based on the thickness of the table surface and the lid.
ALid is thicker than or as thick as the table surface BLid thickness is thinner than table surface

NOTE: A thinner lid requires a slightly larger cut
because the enclosure extends into the cut-out.

Preparing the Cable Cubby
Step 1 — Assemble Connectivity Modules
Connectivity modules allow you to populate the Cable Cubby enclosure with a combination of AAP modules, cable pass-through,
or retractors. Follow the steps below to assemble the connectivity modules of your choice.
Option 1: AAP module
Secure up to three single-space
AAP modules in the AAP frame
plate.
#4-40 Nut with
Captive Washer
Secure the AAP frame plate on the connectivity
brackets, using four of the provided #4-40 module
screws. Use a screwdriver to tighten the screws.

2Insert cables through the bottom of the connectivity bracket.
Connect cables to the AAP modules.
NOTE: After assembling the module, proceed to Step 2 — Install the Modules on page 5.
Option 2: Cable pass-through module
Secure the grommet plate
on the connectivity bracket,
using four of the provided
#4-40 module screws. Use
a screwdriver to tighten the
screws.
Insert cables through the bottom
of the connectivity bracket and
into the holes of the grommet plate. Snap the included
hole plugs into any
unused holes.

NOTES:
• After installing the bracket, proceed to “Step 2 — Install the Modules” to install the power module.
• After mounting the Cable Cubby on the table, install the Retractors (see Installing Retractors on page 8).
Step 2 — Install the Modules
Determine where the connectivity modules and power module will be installed in the Cable Cubby. The modules may be installed
on the left or right side of the enclosure and at various heights.
NOTE: Ensure that there is enough room above the modules for the Cable Cubby lid to close completely.

Mounting the Cable Cubby in the Table
1. See the dimension on figure 3 on page 3 for the mounting hole locations OR have an assistant hold the Cable Cubby against
the underside of the mounting surface.
2. Install the screws in the two center pre-drilled mounting holes on each side, leaving 1/8 inch (4 mm) of the screw head
exposed.
3. Use the two center slotted mounting holes on the mounting bracket to hang the Cable Cubby on the two installed screws.
4. Snug the two screws just so that the Cable Cubby can still be moved on its slotted holes.
5. Adjust the Cable Cubby position and alignment.
6. Tighten the center mounting screws while maintaining the position and alignment of the Cable Cubby.
7. Install the remaining mounting screws and secure the Cable Cubby to the table.

7
Step 1 — Perform height adjustment
NOTE: If the lid is the same thickness as the table, proceed to Step 2: Install trim brackets on page 8.
If the lid thickness is different than the table
thickness, loosen, but do not remove, the
wing bolts (two on each side), just enough
to allow the Cable Cubby to slide up and
down in the brackets.
Raise the unit up or down until the lid is ush with
the table top surface. Use an assistant if necessary.
1
Firmly tighten the wing bolts.

NOTE: If the lid is thinner than the table
surface, it may be necessary to relocate
the wing bolts to the bottom position of
the Cable Cubby.

Step 2 — Install trim brackets
If there is a gap, front and back, between the underside of the table and the Cable Cubby frame, install the trim brackets as follows:
Hold the trim bracket
against the underside of the
table, ush against the Cable
Cubby and centered on the unit.
Mark the three mounting holes.
Drill 1/8 inch (3 mm) diameter pilot holes,
1/2 inch (12.7 mm) deep.
