UNDOR Pro Protect is compatible with most sectional (roll-up) residential garage doors. However, there are several key things to be sure of before ordering:

1. You will need a new 4" wide replacement bulb seal for the bottom of your door. We do not recommend a "Bowsen seal (the type with an inner rubber tube ).

2. Your garage floor must be in good condition, and not have any steps or a "weather lip".

3. Your door should have a single curved track at the top of your door. If you have a double track, UNDOR will not work for you. Check out our "Compatibility Information" section on our Order page for some helpful images.

In most cases, yes.

Most garage doors come standard with a smaller rubber seal. UNDOR Pro Protect will add a 1.25" gap under your door, and the standard seal on your door will not be able to close up this additional gap. Installing a new 4" wide bottom seal allows the seal to compress properly against the floor. Check out our webpage on selecting the appropriate seal: https://undorgarage.com/pages/garage-door-seals

Upgrading your seal is relatively simple, inexpensive, and ensures optimal results.

UNDOR Pro Protect is compatible with most Level 1 and Level 2 charging cables having a maximum diameter of 0.9 inches. It also works great with most garden hoses ! If your charging cable exceeds 0.9 inches in thickness, the cable may not work properly with UNDOR Pro Protect.

No — when installed properly with the appropriate 4" bottom seal.

Unlike basic rubber ramps or wedge-style protectors that leave visible gaps, UNDOR Pro Protect is a permanent solution with a sliding channel cover that seals when not in use.

Replacing your existing bottom seal with a 4" wide bulb seal is the key to a clean, gap-free result.

Aside from replacing the bottom seal on your door with a new 4" wide version, no other modifications are required.

Installation uses basic tools and does not require altering your door panels or track system.

UNDOR Pro Protect is designed to eliminate drafts, debris, and minor water intrusion when properly installed with a new 4" wide bottom seal.

This is not a waterproofing product and will not prevent water from entering your garage.

Performance depends on your specific garage door condition and seal quality.

Most homeowners complete installation in one hour or less using standard household tools.

Please watch our installation video for more information.

Basic rubber ramps may provide some amount of protection for the cable but are not a permanent solution. They often:

• have to be placed in position each time thery are in use.

• Leave a gap under the door
• Allow drafts and pests inside
• Create an uneven threshold

UNDOR Pro Protect is designed as a clean, sealed, permanent solution — not a temporary workaround.
