SNAPP® Screen Installation Instructions

SNAPP® Screen installation is quick, simple, efficient and requires no additional parts.
• NO caps NO covers NO expanders NO adapters NO corners
Most installations can normally be performed by one person of average skill with no special tools.

You can measure and install your own screens - Follow our step by step instructions below

Step 1: Determine the materials you’ll need to order:


  • • SNAPP® Screen extrusions
  • • SNAPP® Screen mounting screws
  • • SNAPP® Screen spline
  • • SNAPP® Screen spline tool
  • • SNAPP® Screen screen material

Step 2: Ensure you have the proper tools available:Screen Porch Buy Now

  • • Measuring Tape
  • • Utility knife (with extra blades)
  • • Screw gun
  • • Spline Installation Tool
  • • Hacksaw or power chop saw fitted with an aluminum/plastic cutting blade. (We find the Freud Diablo series aluminum/plastic cutting saw blade to be one of the best to use - 80 or 96 tooth – based on blade size required. Available at any home center)

Step 3: Determine how you intend to mount (“inside” or “around” opening) (“miter” or “butt” corners)


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. Installation can be with miter or butt corners (or a combination of both if required).


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. Installation can be with miter or butt corners (or a combination of both if required).

Step 4: Width extrusions

  • • Measure the width dimensions and cut extrusion to proper size
  • • Test fit in your opening then predrill for mounting screws (Use the score line to position drill holes)
  • • Place hole 1” from each end and then no more than 12” apart
  • • Install the width extrusions

Step 5: Height extrusions

  • • Measure your height dimensions and cut extrusion to proper size
  • • Test fit in your opening then predrill for mounting screws (Use the score line to position drill holes)
  • • Place hole 1” from each end and then no more than 12” apart
  • • Install the height extrusions

Step 6: Screen installation

  • • Screen installation is similar to traditional screen rolling
  • • Watch Screen Installation Video (above) for complete screening instructions
  • • Fabric screening (polyester, fiberglass, etc.) is recommended. Avoid metal screening
  • • Screening pattern is top, bottom, prime hand side, non-prime hand side
  • • Use only SNAPP® Screen spline tool or 3/32" nylon equivalent
  • • Use only new SNAPP® Screen spline. (do not re-use spline when rescreening)

Roll screen in - then roll spline in.

Step 7: Screen trimming

  • • Run blade along the top edge of extrusion.
  • • Trim location is the same for both sides of the extrusion
  • • Use Caution: Aggressive or deep trimming will damage spline and/or weaken hold.

Watch the complete SNAPP® Screen installation process below


SNAPP® Screen is specifically designed so extrusions are simply butted together when required. (always leave a 1/16" gap between joints). Also, aluminum SNAPP® Screen and PVC SNAPP® Screen extrusions are color matched so they can be used together whenever needed.

Spline / Spline Installation

SNAPP® Screen spline (item: PF-014-500) must be used and fully seated within spline channel for proper hold. Use of other any other spline or failure to fully seat spline will result in screen pull out. Additionally, all spline tools are not the same, it is highly recommended that a SNAPP® Screen spline installation tool (item: TL13) be used for spline installation. (see web store for more information on each item)

Gazebo Installations

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. Also see GAZEBO SCREENS for additional information.

Installing SNAPP® Screen 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 in 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).

Screen Porch Warnng

Warning: SNAPP® Screen is a “build in place” / “screen in place” insect screening system and will not provide fall prevention. Further, insect screenings only intended use is to reasonably stop insects from entering the covered opening.  The misuse of insect screen may lead to injury or death. SNAPP® Screen will not stop persons, children, animals, or alike from falling out of or entering through the insect screen covered opening.
