R. Lang’s Tru Frame Sliding Security Doors

The Tru Frame Sliding Security door is manufactured by the R. Lang Company out of Visalia CA. The R. Lang company has been in business for over 7 decades manufacturing window screens, screen doors, and security doors. One of their latest creations is the Sliding Security Door.

Because they have so much experience under their belt, R. Lang’s sliding security doors are some of the best designed, smoothest operating doors in the market.

Stainless Steel Security Screen Mesh:

At the heart of the Tru Frame Sliding Security door is the woven stainless steel security screen mesh. This stainless steel mesh looks very similar to ordinary screen, but it can’t be kicked in or cut with a knife! It provides excellent two-way visibility, and unsurpassed     bug-tight airflow giving you the ultimate in security and peace of mind. Our customers are always surprised at just how clearly they can see out through their newly installed Sliding Security Screen Door! The screen mesh is only available in the black powder-coated paint finish for maximum two-way visibility and to mimic regular window screen as much as possible.

The outside edges of the stainless steel mesh are held securely in place so the panel can’t easily be kicked in (see Video), and the stainless steel screen mesh can’t be cut through with a knife. The days of having to put up with rusty jail bars mucking up your view and negatively affecting your property values are officially over.


Tru Fame Sliding Security Screen Doors come with a single point locking system. Activated with a throw lever located at the handle, the sliding security door locks in exactly the same manner as most sliding glass patio doors. It is not possible to unlock the sliding security door from the outside because it is not built with a traditional lock with a keyway. This lock’s simple robust design ensures years of trouble- and maintenance-free use.
In addition, an innovative interlock keeps would-be thieves from getting a pry bar behind your sliding security screen door in order to pry it open and forcefully gain entry into your home.

Outer Frame & Mounting:

R. Lang’s Sliding Security Doors slide within a heavy-duty extruded aluminum pre-hung outer frame which is mounted directly to your home. This extruded outer frame is either a single or double wide track to allow one or two sliding security door panels to slide back and forth. The outer frame protrudes out away from the home, 1 3/4 inch for a single door, or 2 7/8 inches for a double door configuration.

The entire door assembly is mounted to your home’s 2X4 walls using very long torx head screws. Once the sliding security door is closed and locked, the heads of the torx screw mounting hardware are not exposed to the outside, thus rendering it impossible for an intruder to remove the door without destroying it in the process.


Even though the R. Lang Tru Frame sliding security doors are heavy duty, they glide effortlessly because they come with fully adjustable wheels on top and bottom containing sealed stainless steel needle ball bearings. These wheels ensure your kids can come in and out of the door incessantly like they always do…. Only this time, your patience will wear out long before your new sliding security door does!

Available Colors

For the best two-way visibility, the sliding security screen door’s stainless steel mesh is always black. The Lock Handles are also always black. The outer frame of the sliding security screen door is available in two standard colors: a powder-coated White paint finish, or an Anodized Bronze finish.

Most customers will choose the color that most closely matches their home’s existing sliding glass door frame color. For an additional fee, you can also get your Tru Frame Sliding Security Door in a Tan or Almond color, as well as a myriad of other custom colors

Unsurpassed Durability

This will be the last screen door you’ll ever need to buy! The door’s heavy-duty construction will help to ensure it’ll put up with your kids and pets with ease!

Because the Tru Frame Sliding Security Screen Door’s frame is constructed of architectural-grade heavy-duty aluminum extrusions, it is guaranteed never to rust and will give you years of maintenance-free breeze! In addition, the Tru Frame Sliding Security Screen Door glides effortlessly on a fully adjustable wheel system containing sealed stainless steel needle ball bearings for years of maintenance-free use.
