Leaf Springs

• Leaf Springs are found on Half Window Screens as well as Window Full Screens.
• These type springs are most common on the Top of many Window Full Screens as well as on the Top or Side of Window Half Screens.
• Leaf Springs are installed in pairs about 3-4 inches from the corners.
• They may be located on the Top or the Side of the window screen depending on the type window.

Tension Springs               

• Tension Springs are found on Half Window Screens as well as Full Window Screens.
• These type springs are most common on the Side of 'Horizontal Slider' Window Half Screens.
• Tension Springs are installed in pairs about 3-4 inches from the corners.
• They may be located on the Top or the Side of the window screen depending on the type window.
• Tension springs will retract fully into the frame if necessary during installation.

Wire Loops (Wood Hardware)

• This 'Combination' of hardware is called "Wood Hardware" as it is normally used on older style wooden single hung windows that open from the bottom.
• Two Wire Loops are attached to the Bottom of the Screen about 3-4 inches from each corner.
• The Jiffy Hangers attach to the side of the outside window frames very close to the top. This allows the window frame to slide up into the Jiffy Hangers, then the bottom of the screen is pulled in toward the window frame.
• The Round Head Screws are screwed into the bottom window sill adjacent to the Wire Loop locations.
• After pulling the bottom of the window in all of the way, the Wire Loops are slipped over the top of the Round Head Screws.

Spring Plungers                     

• Spring Plungers are found on some window screens around the nation.
• There are typically either 2 or 4 Spring Plungers on each screen.
• They can be located on Top, Bottom or Sides at various locations.
• Some Spring Plungers fit into round holes making accurate measurements critical.
• Some Spring Plungers simply fit into the track running the full length of the window frame and accurate placement may NOT be critical.
• When ordering, you must specify the exact location of the Spring Plungers as measured from the corners. (EXAMPLE: 2 plungers on top 3 1/4 inches from corners).

Bale Springs                                 

• Bale Springs are common on many newer Aluminum windows and may work on some older ones.
• Bale Springs are found on Half Window Screens at the Top.
• The Bale Springs clip behind the window center bar to hold the top of the screen in place.
• Bale Springs are installed in pairs about 3-4 inches from the corners.
