Simply bolt it to the floor using the fixings supplied and place your caravan hitch onto the ball, lower the sliding mechanism onto the top of your hitch and secure this in place with 2 padlocks into the holes that match up (padlocks not supplied).
Pictures shows how (rectangular / shutter) padlocks cannot be cropped, also there is the added anchor point for a chain should you want extra security or secure any other items.
Can be used in conjunction with other hitch locks where the hitch lock does not cover the hitch were the tow ball goes in as shown in some of the pictures.
Fully galvanised so no rusting, chipping or flaking issues.
