Viewguard Security Screen Door – The Security Door In Disguise!

Learn more:

You’ve always wanted to be able to open your door to get the breeze, but were concerned about creating an “open door policy” for the bugs…. and thugs! A security door would be the next logical conclusion, but you simply don’t care for the tacky jail bars or overly busy designs found on most traditional steel jailbar security doors… and besides, who wants to deal with painting and repainting a steel security door that always rusts?!

With this very dilemma in mind, the R. Lang Company (based out of Visalia, CA) decided to revolutionize the security door industry by creating a security door that DIDN’T LOOK LIKE A SECURITY DOOR! But how do you design a security door that LOOKS like an ordinary screen door, but is as strong and robust as a reinforced security door? After many years of research and design, the Viewguard Security Screen Door is the fruit of their labors!

Built to look like a simple, nondescript screen door, the Viewguard security screen door is a security door in disguise because it has NO BARS AND NO OVERLY-BUSY DESIGNS to obstruct your view or detract from your home! Just a simple looking outer frame and a specialized stainless steel mesh!

Features & Construction

At the heart of this door, the specialized stainless steel mesh panel LOOKS like ordinary black screen fabric, but it’s actually a super tough protective barrier between you and any uninvited guests!

It’s nearly impossible to kick in, and can’t be cut with a knife, and yet, visibility looking through the screen is amazingly clear! And the airflow?? The airflow through this revolutionary stainless steel mesh is better than any other security door on the market!

The stainless steel mesh is very strong, affords awesome visibility, and allows breathtaking airflow!

The specialized stainless steel screen is locked into the outer frame with a patented mesh clamping system. The clamping system keeps the stainless steel panel rigid, and prevents intruders from being able to kick the stainless steel screen out of it’s frame.

The door’s outer frame is constructed of a beefy architectural grade aluminum extrusion! Built above and beyond the call of duty, the four separate outer frame pieces are miter cut and then joined at the corners with a super strong internal key corner system keeping the door laterally stiff and strong.

Because the Viewguard is made up entirely of high-grade 6063 T-5 architectural aluminum and 304 series marine-grade stainless steel, it’s ideal for installing in areas that don’t have an adequate overhang to keep the rain away! Areas such as side garage doors often prove dismal for traditional steel security doors which rapidly rust when exposed to wet winter conditions!

The Viewguard is backed with a LIFETIME NO-RUST WARRANTY! Wouldn’t you rather have a security door that will look good and be maintenance free for a lifetime?

One of the Viewguard’s coolest features is the continuous gear hinge system. Rather than using a run-of-the-mill pin hinge, the R. Lang Company chose to go all out by selecting a commercial grade continuous gear hinge system! One of the most expensive components on the door, it distributes the weight of the Viewguard along the entire length of the door! Unlike pin hinge systems that squeak, or are subject to break-in, the Viewguard’s commercial grade gear hinge system allows the door to be opened and closed smoothly for a lifetime of maintenance free use!

Also a first in the security door industry, the Viewguard is mounted securely in place with recessed stainless steel tamper resistant torx bolts! Because the bolts are recessed, the bolt heads are neatly covered with low profile caps! Forget the rusting, ugly exposed one-way bolts of traditional security doors! The Viewguard keeps it clean, simple and elegant!

No Gaps on the tops and sides

To make the Viewguard Security Screen door as bug-tight as possible, the top and sides of the Viewguard’s tubular outer frame are lined with gray pile weather stripping, and a rubber door sweep is installed across the bottom of the door. No gaps means no uninvited little guests!

No Gaps across the bottom

When at all possible, a new aluminum threshold is installed over the top of your house door’s threshold in order to ensure that your new Viewguard Security door ties in seamlessly with your home’s existing door for a very clean, custom, and professionally installed look! No gaps across the bottom of these doors means no mice, lizards, snakes or insects!
