The best surface to fix a safe into is concrete as this provides the most solid fixing. If you have a wooden floor please check with your insurance company they are happy with this. On a wooden floor the joist is the best point to fix to as this is a fixed point below the floor and generally more solid.
To install the safe to a floor you will need to choose an ideal location, put the safe into position and then mark the hole. Then remove the safe and drill where you have marked, check the instructions or bolt size for the size of hole that you will need to drill. Once your fixing hole or holes are drilled put the safe back into position and then using the bolts provided tighten them up.
You will need various tools to complete this task such as a drill or socket set, if you do not feel 100% confident then we can also arrange installation for you. Please contact us for more details.
