Is Your Home Vulnerable to Sliding Door Leaks?

When wind-driven rain sneaks through sliding glass door tracks, it can feel like just a drip—but it’s often the start of serious damage.

Puddles forming near your door track signal costly flooring or drywall repairs
Storm stains? Probably mold forming behind walls
Moisture creeping in unnoticed weakens finishes, baseboards, and structure

Don’t wait for damage you can’t see. Protection at the track level can stop it before it spreads.

How the HF Diverter Works: Engineered for Total Protection

Invented by South Florida resident Howard Foster, the HF Diverter is a patented sliding door track insert that blocks water and strengthens security—without permanent modifications or complex tools.

Drop-in design that forms a watertight barrier in your sliding door track
Custom-sized to fit your exact sliding glass door dimensions
Resists wind-driven rain and high-pressure flooding
Easily removed and reused—season after season

Security Protection That Works Behind the Scenes

Your sliding glass door may be inviting problems beyond water. The HF Diverter adds a tamper-resistant barrier at the track—strengthening your security without visible hardware.

Hard to manipulate from the outside—unlike basic locks
Maintains door functionality while enhancing defense
Designed to stay in place even during storms and intrusive pressure

Custom-Fit Protection: Because Every Door is Different

Generic guards often leave gaps, fall out, or interfere with door operation. HF Diverter is crafted to match your door and climate.
