Support Bars

Support bars help to prevent hour glassing and provide more stability to the overall frame by creating additional points of contact. Support bars do not need to be installed in the center to be effective.

There are two methods that we utilize on a daily basis:

  • Common: As the name implies, this is the most common method used in the industry. Here a pair of clips (SFC112) penetrate into the support bar (FRM516CB) at each end and the assembly is held in place in the overall screen frame by the retainer spline. This is normally used when installing support bars in our FRM516 or FRM716 frame materials. This may also be used with our FRM1716 but it is not recommended when FRM1716 is used for porch application.
  • Structural: This method requires mechanical fastening of the support bar. This creates a much more structurally solid screen frame. The point of contact between the the support bar and screen frame is solid and cannot normally be separated without damaging the screen frame or the support bar itself. This method is used standard with our FRM516E, FRM1716E, and FRM1716 materials.

Shown left: At the far left is our FRM516CB with a SFC112 installed. On the right hand side are our FRM1716E, FRM516E and FRM1716 materials. Notice how these 3 frames are notched. By notching, we have created a mounting flange for the support bar. The notch can be created with a table saw, hack saw, or any other method that will provide a clean mounting surface.

Shown left: SFC516CB and SFC112 in place prior to screening. During screen installation the retainer spline will hold the SFC112 in place. (notice how the SFC112 protrudes out of the FRM516CB and folds into the frame materials spline channel)
 



(3 photos above L to R) FRM516E, FRM1716E, and FRM1716 all shown with support bar installed. Note how the flange overlaps the overall screen frame and is secured in place. The flange you create may be a full coverage flange, as we use, or smaller.

Be sure to install all bars with the same orientation. Panels in close proximity to each other will not look professional if the orientation changes from panel to panel.
