Congratulations on your purchase of a MaxSeal® Door by Security Boss®.
The following is a step by step guide for installing your MaxSeal® product.

Always wear eye protection and gloves when appropriate.

Step 1: Be sure that you have ordered the correct size door for your pet. For long term use it is best to size the pet door so that the top of the door is about 2 inches taller than your pet's shoulders. The resulting bottom of the opening should be a comfortable step over height.

Step 2: Check the package you received to make sure that it contains all the necessary parts.

Complete Kit includes:
MaxSeal® French Door Model
Insulated Security Panel with replacement rivets
1-1/2" #6 Phillips Head Screws
1-1/4" #6 Security Screws for Tamper proof installations
7/64" drill bit Allen Wrench

Tools Needed:
Electric Drill
Putty Knife

Step 3: Select the pane of glass in the French Door you plan to mount your MaxSeal® pet door.

Step 4: Remove the molding around the selected pane of glass where you want to install the pet door. If you are removing more than one panel of glass, remove molding around this area.

Step 5: Remove the pane of glass and re-attach the molding in same location as removed in Step 4.

Step 6: Now you are ready to install the MaxSeal® French Door in the glass opening. Separate the interior and exterior MaxSeal® door frames. Remove the Insulated Security Panel from the inside frame.

Step 7: Put the inner frame (the one with the insulated security panel) into the glass opening in the French Door. Put the outside frame into MaxSeal® door and sleeve the pet door frame together until seated against French Door molding surface.

Step 8: Using the pre-drilled pilot holes and supplied drill bit, drill and insert one screw. Make sure the door is level. When level, tighten the inserted screw. Affix remaining screws into place using the pilot holes as guides (Security Boss Manufacturing® has included One-Way Security Screws as well as Philips head screws to give customers a tamper-proof option in their door installation.)

Step 9: Once the pet door is installed you can fill any gaps or seal the edges with caulking if desired.

General Use Information: The Insulated Security Panel will slide into place and fasten with the dead bolt lock. When removing the Security Panel from the unit, apply a slight inward pull to the panel handle while lifting. Since the panel is tight fitting in the channel, this pulling pressure will ensure that the panel rivets do not catch on the frame of the unit.

The dead bolt is retracted by pulling on the handle and turning the handle clockwise, or right, approximately a quarter of a turn. To lock the deadbolt, continue to turn the handle of the deadbolt another quarter turn and the lock will extend into the locked position under spring tension. DO NOT TURN THE HANDLE OF THE LOCK COUNTER CLOCK WISE OR LEFT, AS THE LOCK WILL LOOSEN AND NOT WORK.


Replacement rivets have been included with your hardware kit should the ones on the MaxSeal® Insulated Security Panel work loose. Install by pressing the two pieces together from opposite sides of the panel in the pre-drilled holes. The thumbscrews that attach the flaps are factory tightened. Through use, the thumbscrews occasionally loosen and therefore should be checked regularly for tightness. Re-tighten the thumbscrews using the included Allen wrench.

The magnets on all MaxSeal® doors are adjustable. This allows a precise seal no matter the weather or size of the flap throughout the years. The magnets are positioned in the frame with a pressure fit. The magnet is held by an aluminum carrier that can slide in and out of the painted frame rail. The best way to lift the magnet is by using pliers to lift the magnet out of the frame rail. BE SURE TO COVER THE MAGNET AND CARRIER WITH A TOWEL TO PREVENT SCRATCHING OF THE FRAME AND CARRIER. Only lift the magnet the minimum required to make the magnet touch the strike plate on the flap. If the magnet carrier becomes loose within the frame after adjustment, simply pry the two legs of the magnet apart and reinsert into the frame rail. The magnets are adjusted correctly when there is 0" of airspace between the magnet and the strike plate. Once the magnets are positioned properly, your replacement flaps is installed.


Child Safety:
Security Boss Manufacturing®, LLC., recommends that households with small children need to exercise proper judgment with leaving their children unattended in any area with a pet door. Pet doors come with locking panels and locking devices, using these devices minimizes any risk, but does not replace proper parental supervision.

We recommend that any consumer that installs their own pet door wear eye protection and be familiar with the construction procedures and tools of installing a pet door.

Virtually all doors use magnets for the activation of the pet door as well as in the sealing of the flaps. Customers with certain medical devices, for example Pace Maker patients, should consult their physician.
