This is a bracket that mounts to a 3" metal rail, to be used without drilling into the rail. Separate hardware will need to be purchased. I also placed a thin pad between the bracket and the rail to reduce the chance of scuffing. This has worked out well in our home.
I do not take responsibility for your poor prints or your children or dog breaking through the bracket and falling down the stairs. Bracket is very durable, but I take no liability of its use once printed by someone else.
