MaxSeal French Door Model MaxSeal French Door Example

MaxSeal French Doors are made to order to fit the opening created by your existing panes of glass. You can replace one or more panes of glass to make room for a pet door. Some customers even will enlarge the opening by cutting into the side or footer of the door.
For more info see Installation Variations

These doors are ordered based on the opening that they will be installed into. If you are replacing one pane of glass, simply measure the exposed glass as you see it; (This will be the opening that the pet door is installed to). If you want a larger pet door than the size panes in your door, simply measure the opening you will have (more than one pane or larger due to cutting into the side or bottom of door).

Special Note: Your French pet door will have a flap size that is 2" smaller in width & height. (Due to the frame of the door itself). If you measure your pane of glass as 10"w x 10"h, then your pet door will have a flap that measures approx. 8"w x 8"h.

Important Notes:
 1. If you have a single panel of glass with faux partitions in your door, do not attempt to cut the glass.  Most all doors (Unless very old) are made with safety glass.  If you attempt to cut it, the glass will shatter
  2. These doors are custom made. You will be emailed a custom sign off release that you understand these are custom made an non-refundable. Make sure of your measurements or call us for assistance.
 3. Our Pet Door Experts are here to assist in anyway we can, however, the customer bears ultimate responsibility for ordering the correct item and installing properly in the appropriate door.

Installtion Sequence for Installing a Pet Door into French Pane Doors

Measuring for & Installing your French Door Pet Door is very simple. (You must have individual -removable panes of glass. You cannot cut an opening into a single-solid pane of glass, your entire door glass will shatter as doors are made with Tempered-Safety glass.)


Step A: Measure the exposed glass pane as you see it; without removing the molding. The door made for you will have a flap that is 2" smaller in width & height. (Make sure this resulting flap size will be large enough for your pet.)


Step B: Remove the molding around the selected pane of glass where the pet door will be installed. (If you are using more than one pane, remove molding around area.).

Step C: Remove the pane of glass and put the molding back around the opening (without glass pane).

Step D: Your pet door comes apart into 2-frames. These frames sandwich the opening and adjust to the molding thickness. Drill pilot holes for screws (the 2-frames each have a lips that glide over each other to adjust to the molding thickness. Where these two lips overlap is where the pilot holes are drilled). Put screws into pilot holes and tighten.

Note: you may at a later time remove the pet door and re-install the pane of glass.
