MaxSeal® PRO Pet Door
Best Insulating Dog Door for Walls
Most Secure Pet Door | Durable Hinged Flaps
The MaxSeal® pet door is made with high grade aluminum material that is naturally rust resistant. This door will not only last but will look great throughout the life of the door. The durable piano hinged vinyl flaps are UV treated and weatherized to prevent shrinking, cracking, discoloring and warping. Most flap brands simply do not hold up against harsh environments (direct sunlight, extreme temperatures, overuse, etc). Staggered stainless strike plates are riveted to the sides and base of the flap, connecting to powerful embedded magnets in the aluminum frame, creating an exceptional air seal.
Best Pet Doors by Design™The MaxSeal® PRO comes standard with a 10" trim-to-fit solid aluminum tunnel. For larger walls a 16" trim-to-fit tunnel is optional. This solid tunnel design deters moisture issues that can develop in cheaper design products. Indoor / Outdoor carpeting is included with your purchase to line the sides and bottom of the tunnel. We recommend using silicone to adhere the carpet to the tunnel. This will allow you to easily remove the carpet for replacement every few years. Adhesive can make this removal process very difficult.
Note: Existing MaxSeal® Customers can Upgrade their MaxSeal models by purchasing the interior security panel and the hinged replacement flaps for their size of door. Call us if you would like any assistance.

Congratulations on your purchase of a MaxSeal Door by Security Boss.
The following is a step by step guide for installing your MaxSeal product.
A SAFETY REMINDER!
Always wear eye protection and gloves when appropriate.
Tools You May Need:
Flat tipped screw driver
Scissors or snips
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 wall model (includes inner frame with attached tunnel and outer frame)
Indoor Outdoor carpet
Insulated Security Panel
1-1/4 inch #6 Phillips Head Screws
1-1/4 inch #6 Security Screws for Tamper proof installations
7/64 inch drill bit
Tools You May Need:
Tools you may need: (will vary depending on the type of wall where you install the pet door)
Circular saw with wood or masonry blade
Drywall saw or jigsaw
5/16 inch masonry bit (if installing in concrete)
Philips head screw driver
Standard head screw driver (for Security Screws)
Step 3: Find a suitable area for your wall model. Wall models have an Insulated security panel that lift out vertically (side loaded panel models are available as needed). Make sure there is enough room to remove this Panel. To install in a framed wall, place the door between studs. Mark the stud locations and position the door between the studs. Check both sides of the wall to make sure the area you cut is free of wiring and plumbing.
Step 4: Position the MaxSeal tunnel against the interior wall. Trace the perimeter of the tunnel upon the wall. Check the dimension of the wall marking against the measurements of the tunnel. Make sure your opening is square and level.
(We recommend that you use the rough-cut information below as sometimes the outer perimeter of the tunnel can vary. You may also make a template with the rough-cut information for your size pet door, then trace from the template on the wall).
Based on door sizes
Rough Cut Required
8 1/8x 9 5/16
9 1/8x 10 13/16
11 1/8 x 13 13/16
13 1/8x 17 13/16
13 1/8x 21 13/16
13 1/8x 26 13/16
14 1'/8x 25 13/16
17 1/8x 21 13/16
17 1/8x 25 13/16
17 7/8 x 33 13/16
The above measurements are exact dimensions, you may add slightly depending on the accuracy of your cut.
Step 5: Cut a small hole near the center of the traced outline in step 4. Look for obstructions within the wall. The smaller the opening the easier the repair should obstructions be found. Use your hand to feel for any obstructions that may not have been seen.
Step 6: If there are no obstructions then cut the inside wall on the lines traced in step 4. Use a drywall saw or utility knife. Once the interior lines have been completely cut, remove the drywall and insulation from the opening.
Step 7: At each corner of the cutout, use a long drill bit to drill through the exterior fascia. Use a Masonry bit for stucco or stone exterior construction.
Step 8: On the exterior wall, find the corner holes you drilled in Step 7 and draw your tunnel outline on the wall. Make sure your opening is square and level.
Step 9: Drill two additional holes at each corner that are on the tunnel outline. Elongate these holes so you can insert a reciprocating saw blade.
Step 10: Use a reciprocating saw to complete the exterior cutout of the opening.
Step 11: Place the inside frame with attached tunnel through the wall cutout. From the outside, hold the inside frame tight against the wall by reaching through the door opening. Mark the tunnel with a marker along the outside wall.
Step 12: Remove the interior door frame and tunnel from the hole. Cut the tunnel along the marked lines in step 11 with tin snips to make the tunnel fit your wall thickness.
Step 13: Insert the inside frame and tunnel back into the opening. From the exterior, Sleeve the outside frame into the tunnel. Use the supplied drill bit to drill through the pre-drilled holes into the tunnel. Insert supplied screws into the drilled holes. The number of side screws varies with the size of pet door. (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 14: Caulk between the outside frame and the outside wall at the top and both sides. DO NOT CAULK AT THE BOTTOM OF THE OUTSIDE FRAME. This will restrict the drainage of moisture from inside the door.
Step 15: Measure the width of the tunnel between the door frames and cut the included carpet to the correct width and length to cover the distance between the door frames. To keep the carpet in place use silicone adhesive. Press the carpet into the bottom of the tunnel first, then attach it to the sides of the tunnel.
Step 16: Use window cleaner and a soft towel to remove any fingerprints from the interior or exterior flaps
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 no airspace between the magnet and the strike plate. Once the magnets are positioned properly, your replacement flaps is installed.
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.
