18V Battery Swivel Cable Lock

I recently posted an Instructable titled "Cordless Power Tool Conversion 18VDC to 120/240VAC". In the tutorial I go thru step-by-step instructions to modify a dead 18V Ryobi battery into an adapter to be used with an AC/DC power supply.

In the adapter, I installed this swivel cable lock to allow the cable entering the battery case to be positioned either facing foward or rearward, depending on the tool being used.
