Parts of a Window Guard

Simple Yet Strong Design

Guardian Angel Window Guards are sleek and simple while complying with the ASTM F 2090-13 standard for window fall prevention devices with emergency escape release mechanisms.

  1. End Post - The end posts are made from 3/4” square tubing and mount to the frame of your window.

  2. Cross Bar - These cross bars provide the main stability for the window guard and can telescope to adjust the width/height of the guard. Our window guards come in either 3, 4, or 5 cross bar models depending on the fixed side dimension.

  3. Support Bar - This support bar provides structure for the cross bars and tie the assembly into one piece.

  4. Adjustable Side - This side of the window guard telescopes to accommodate a range of window widths.

  5. Fixed Side - This side of the window guard has a fixed dimension and is typically selected for how wide open your window is. For example for sliding windows, you pick the fixed side length according to how wide the window opens.

  6. Release Button - Each guard is equipped with 4 quick release buttons for installation, removal, and emergency situations.

 
 

Sizing & Fit

To select the right size guard (or guards) you’ll want to measure your window opening. See below for measurement guides based on window type.

3 Measurement Steps (using the diagrams above!)

  1. First measure the MAXIMUM OPENING of your window. This measurement will coincide with the fixed side of the window guard. Typically this will be the longer of the two dimensions although it doesn’t need to.

  2. Next measure the WIDTH/HEIGHT of the window opening with the window fully open. This will define the adjustable side of the window guard. This dimension will also determine whether the guard will be a 3, 4, or 5 cross bar model.

    Rather than using a larger 4 or 5 cross bar model for larger windows, we recommend using multiple small guards. This gives you the flexibility to mount two guards side by side, or you can mount one on each end of the window allowing for both the top and bottom windows to be opened if desired.

  3. Last measure to ensure you have at least 3/4” depth of trim to mount the guard to. This is pretty standard but there are exceptions! With your window fully closed you should be able to measure at least 3/4” from the face of your window to the edge of the trim. If the depth of the frame is less than ¾ inch, the guard will need to be installed on the outside of the window frame (on the molding or wall around the window). Please reach out to us before ordering for support!

Fit

Now that you have your window opening dimensions you can select your window guard fitment. Window guards can either be installed one per or multiple per window for maximum flexibility. For example for a large sliding window you could install two narrow guards side by side or one wide guard.
