The easy access control panel allow you to see the mode in which the door is operating in while allowing easy changes to be made. This wall version of the Smart Door has two sleeve tunnels that you affix the electronic door. This tunnel assemble will fit walls from 3 1/2" to 7" thick. There are no additional tunnel extensions available for the Small Smart Door. The Large Smart Door does have the option to add additional tunnel extensions for thicker walls. This electronic door is not recommended for cats as the flap may be too difficult to push through.
