Used on any of the top slides to add security to the drawer.
The customer will need to drill two holes in the inner side lip of the drawer to allow a nut and bolt to be used to secure the cover in place.
With the cover in place you can no longer access the rear of the drawer even if the top slide has been pulled out.
This means that if someone breaks into the vehicle they would not be able to just simply slide the top open to get to the back of the drawer.
