Before You Buy

Key Buying Factors

01

Mounting Type

Choose between door-mounted or wall-mounted based on your home's construction. Door-mounted models are easier to install, while wall-mounted provide more flexibility in placement and can be larger.

02

Weatherproof Seal

Look for dual-flap or magnetic seals that prevent drafts, rain, and snow from entering. The MaxSeal line features our team's favorite weather-resistant designs.

03

Flap System

Single-flap is simpler and more flexible; dual-flap adds insulation and better security. Consider your climate and how much energy efficiency matters.

04

Locking Mechanism

Sliding or twist locks allow you to restrict pet access (e.g., keep pet in at night). Some models feature dual locks for added security. We recommend models with easy-to-use locks.

05

Pet Size Compatibility

Measure your pet's height and width at the shoulder. Check the actual opening size of the pet door, not just the overall frame. Our picks include small to extra-large options.

06

Durability & Materials

Reinforced frames, impact-resistant flaps, and UV-stabilized materials ensure longevity. Security Boss products use high-quality plastics and aluminum components.

Living With It

Care, Cost and Maintenance

Clean Flaps Regularly

Wipe flaps with a damp cloth to remove dirt and paw prints. Use mild soap if needed. Avoid abrasive cleaners that can scratch the plastic.

Check Seal Integrity

Inspect weatherstripping and magnetic seals every few months. If gaps appear, replacement strips are often available from the manufacturer.

Lubricate Hinges and Locks

Apply a silicone-based lubricant to moving parts yearly. This prevents sticking and ensures smooth operation in all weather.

Pro tip

When measuring for a pet door, always measure your pet's width at the widest point (usually hips) and add at least 1-2 inches for comfortable passage.

Frequently asked questions

What is the difference between door-mounted and wall-mounted pet doors?
Door-mounted models install in an existing door panel, which is simpler and less invasive. Wall-mounted models require cutting through wall materials but offer more placement flexibility and often larger sizes.
How do I measure my pet for a pet door?
Measure your pet's height from floor to top of shoulders, and width at the widest point (usually chest or hips). The pet door opening should be at least 1-2 inches taller and wider than these measurements.
Are these pet doors secure against intruders?
Security Boss MaxSeal doors feature robust locking mechanisms and sturdy construction. However, no pet door is impenetrable. We recommend using the lock feature when away, and consider additional security measures like a security bar.
Can I install these myself?
Yes, all models come with installation templates and instructions. Basic tools required include a drill, saw (for wall-mounted), and screwdriver. We recommend DIY for door-mounted, but wall-mounted may require professional help if you're not comfortable cutting into walls.
How do I maintain the pet door for longevity?
Regularly clean the flaps and frame with mild soap and water. Lubricate hinges and locks annually. Check weather seals for wear and replace as needed. Ensure the flap moves freely to prevent stress on the mechanism.
