Upgrade Your Slider

Better Grip. Better Security. Built for Your Sliding Door.

Whisper Slider Door is proud to offer the newest sliding door upgrades from Handle-Man—including the FullGrip™ Exterior Handle and LeverGuard™ Lock System.

Designed to improve both everyday use and security, these innovative upgrades give homeowners a more comfortable way to open their

sliding glass door and a stronger, easier-to-use locking solution.

FullGrip™ Exterior Handle

Traditional sliding door handles can be small, awkward, or difficult to grip. The FullGrip™ Exterior Handle is designed for a more natural, full-hand grip that makes opening and closing your sliding glass door easier.

Benefits of the FullGrip™ Handle

Comfortable full-hand grip
Durable die-cast aluminum construction
Clean, modern appearance
Designed to retrofit many existing sliding glass doors
Available in multiple finishes
Ideal for everyday convenience and easier access

LeverGuard™ Lock System

If your sliding glass door still uses a traditional thumb-turn lock, the LeverGuard™ Lock System offers an upgraded approach to securing your door.

The patent-pending LeverGuard™ replaces the standard thumb-turn with an easy-to-operate lever actuator while providing a clear visual indication that your sliding glass door is locked.

Why Upgrade to LeverGuard™?

Easier locking and unlocking
More secure engagement
Visible locked position
Comfortable, intuitive operation
Integrates with the FullGrip™ Exterior Handle
Professional installation available

Already Have a Sliding Door Lock?

A standard lock may technically secure your door, but that doesn’t mean it provides the best combination of security, access

ibility, convenience, and peace of mind.

Handle-Man’s newest products are designed specifically to improve the way homeowners interact with their sliding glass doors every day.

Whether your current handle is difficult to grip, your lock is frustrating to operate, or you simply want to upgrade an aging patio door, Whisper Slider Door can help determine whether a Handle-Man upgrade is right for your home.

Professional Handle-Man Installation

Proper installation matters.

Whisper Slider Door can professionally install Handle-Man products while inspecting the condition and operation of your sliding glass door to help ensure everything works together properly.
