** CAUTION **
Aggressive or deep trimming
will damage spline and/or weaken hold.
“Around” the opening with butt corner installation: Top and bottom extrusion (widths) are always sized to be the full opening + 7/8”. (This will give you the needed additional length for the notch and overlap required on each end) Typically the notch will be 7/16” x 5/8” but size can change based upon installation conditions. Heights are cut to fit in between the width extrusions.
Safety Warning: This product is a “build in place” / “screen in place” insect screening system and will not provide fall prevention. Further, insect screening and sunshading materials only intended use is to reasonably stop insects from entering the covered opening. The misuse of insect screen and sunshading materials may lead to injury or death. These items will not stop persons, children, animals, or alike from falling out of or entering through the insect screen or sunshading material covered opening.
Instaling SNAPP® in Arches / Radii
PVC: It is generally much easier to install the extrusion using the “around” the opening method. The PVC extrusion simply flexes easier. On a slow or long radius, the extrusion will fit with little effort. On fast or tight radii you may need to employ a heat gun to help soften the flange. You should also reduce the screw spacing to 6” or as needed for your application. The same points are true for “inside” the opening installations except that relief cuts may be required to compress the extrusion in fast or tight radii. Test fit the extrusion prior to determine the best installation method.
ALUMINUM: All points as noted above except that on fast or tight radii use of a commercial bender may be needed. Caution: When using a commercial bender, fast or tight radii bends may crack the applied powder coat finish. Best practice is these cases is to only bend unfinished (mill) extrusions and apply finish after bending -or- use the appropriate color matching PVC extrusion in the arch location(s).
Step 6-1: Spline in top of opening and fully attach screen material. Ensure spline is fully seated into spline channel.
Step 6-2: Spline in lower extrusion. Pull downward tension on screen material while installing spline. This will tighten up the screen panel substantially. Most of your tension will be obtained during this step. Ensure spline if fully seated into spline channel.
Step 6-3: If your right-handed, install the spline on the right side next / If your left-handed, install the spline on the left side next. Ensure spline if fully seated into spline channel.
Step 6-4: Install spline in final remaining side. Pull lateral tension on the screen while installing spline. This step will tighten up the screen fully and create a clean flat installation. Ensure spline if fully seated into spline channel.
Adjustments for metal materials: Screening pattern is the same except that the screen should be fully worked into the extrusion prior to installing spline. This eliminates trimming. To achieve this, overlap the top extrusion by 1/8” to 3/16” with the screen material. Work the screen into the extrusion fully. Angle cut the corners last. Install the spline in one full motion across the top. Repeat steps for bottom extrusion while putting downward tension on the screen. Repeat steps for prime hand side. Repeat for non-prime hand side – again while pulling lateral tension. If performed correctly there should be no trimming and screen should be flat with a clean appearance. Another trick (not required) is to use a step spline tool to form a clean edge prior to installing spline …. This will give a crisp clean edge all around.
Screen material is installed in a
traditional screening fashion.
Use only a 3/32” or 1/16” nylon
wheel spline tool and new OEM spline.
(do not re-use spline when rescreening)
Safety Warning: Please follow all common and accepted safety practices and ensure that you are proficient in the proper and safe operation of any tools, equipment or procedures required to install this product.
Standard Installation Instructions
• Modify directions as needed based upon your application •
• Extrusions can be butted together for longer runs •
• Leave a 1/16” gap between all joints •
• Largest tested singe opening size: 10’ x 12’ •
INSIDE THE OPENING
As the installation name implies, the extrusion is installed within or “inside” the opening. The extrusions can be mounted at any point within the opening provided enough room exists for screen installation. (Also see notes section below) Installation can be with miter or butt corners (or a combination of both if required). Click on any item at right to enlarge.
AROUND THE OPENING
When installing the extrusion “around” the opening, the extrusion head will be located outside of the opening itself. This gives a picture frame effect or reveal which tends to be complimentary to most installations. This is the preferred method when screening arches. (Also see notes section below) Installation can be with miter or butt corners (or a combination of both if required). Click on any item at right to enlarge.
Spline must be properly sized and fully seated within the spline channel for hold. If spline is incorrect in size, or not fully seated, installation failure will occur. Use our .170 poly spline for all fiberglass and Super Screen screen materials. Use our .140 poly spline for all .025g sunblocking screen materials. Do not reuse poly spline - it is a one time use product. Do not use PE or rubber spline - failure will occur.
A cautionary note when installing the extrusion. (Particularly along the base of openings or when installing deep within an opening) Test fit at the location of installation and ensure you will be able to fit your hand and the spline tool for screen installation. The design of the extrusion allows for installation as installed but some may find this too tight. In these cases, add a spacer as shown.
Column faces will typically be angled away from each other in traditional gazebo installations. The extrusion can be mounted directly to the columns or a wedge can be installed first. Extrusion can be mounted “inside” or “around” the opening or as required to facilitate installation.
“Inside” the opening with butt corner installation: Top and bottom extrusion (widths) are always sized to be the full opening. Heights are cut to fit in between the width extrusions. The gap shown in the photo left is normal and notching of the height extrusions is not required.
