LockIt
®
Lacing Brackets
Use the included LockIt Lacing Brackets to securely fasten the HDMI cable as follows.
1. Plug the HDMI cable into the panel connection.
2. Loosen the HDMI connection mounting screw from the panel enough to allow the LockIt lacing
bracket to be placed over it. The screw does not have to be removed.
3. Place the LockIt lacing bracket on the screw and against the HDMI connector, then tighten the
screw to secure the bracket.
ATTENTION:
• Do not overtighten the HDMI connector mounting screw. The shield it fastens to is very
thin and can easily be stripped.
• Ne serrez pas trop la vis de montage du connecteur HDMI. Le blindage auquel elle est
attachée est très n et peut facilement être dénudé.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing bracket as
shown.
5. While holding the connector securely against the lacing bracket, use pliers or similar tools to tighten the tie wrap, then remove any
excess length.
