Designed to screw into the trim around a door frame to secure network or speaker cables. Put a screw through the hole and add a wire tie (cable tie)-- done. The wire tie can be replaced without unscrewing anything. There is enough clearance and a slight upward ramp where the wire tie fits through so the tie exits upward.
When printed, the holder is about .63" wide x .78" tall.
Sketchup file included for modifications.
