Step 3: Install KRT-3
Attaching KRT-3 to a Kramer TBUS
Use this procedure to mount KRT-3 onto the following Kramer TBUS units: TBUS-1AXL, TBUS-3xl, TBUS-4xl, TBUS-5xl,
TBUS-6xl and TBUS-10XL.
Before mounting the KRT-3 onto a TBUS, you need to configure and install the TBUS inner frame (including inserts and
power sockets) and mount the TBUS onto a table.
Remember to prepare an opening in the TBUS inner frame for the retracting cable connector (for example,
use the Kramer WCP pass-through insert).

To attach KRT-3 to a TBUS:
1. From under the table, slide the KRT-3 onto one of the side
walls of the TBUS.
Make sure that the fixed cable is directed downwards and
the retracting cable is directed upwards.
2. Use the appropriate Allen key to fix the KRT-3 by tightening
the Allen bolt firmly in place and pass the retracting cable
end through the cable pass-through bushing.
The KRT-3 is now firmly fixed in place.
Attaching KRT-3 (as a Standalone) to the Underside of a Table
The thickness of the table should be at least 18mm so as not to
damage the table. Kramer Electronics is not responsible for any
damage caused to the table.
To attach KRT-3 to the underside of a table:
1. Place the KRT-3 under the table in the desired location.
Make sure that the retracting cable faces the edge of the
table.
2. Pass the 3 M4x50 screws through the table screw openings
and tighten them to fix the retractor under the table.
