Quick Reference: What You Need
Before You Start: Frame-Mount vs Wall-Mount
How you measure depends on your mounting method. Understanding this first will ensure accurate measurements.
Frame-Mount
Bars attach directly to the window frame. Best for wood or vinyl frames with sufficient depth.
- • Inside frame width
- • Inside frame height
- • Frame depth (must be 1.5"+ for mounting)
Wall-Mount
Bars attach to the wall around the window. Required for metal frames or thin frames.
- • Total opening width (including frame)
- • Total opening height (including frame)
- • Add 2-4" for bracket overlap
Step 1: Measure the Width
The width measurement is the horizontal distance your bars need to span.
For Frame-Mount:
- 1Measure from the inside left edge of the frame to the inside right edge
- 2Take measurements at top, middle, and bottom of the window
- 3Use the smallest measurement (windows aren't always perfectly square)
SWB Bar Width
All SWB models have a fixed 16-inch bar width. For windows wider than 16", install multiple units side-by-side. For example, a 32" window needs 2 units.
Step 2: Measure the Height
The height measurement determines where your bars will be positioned vertically.
For Frame-Mount:
- 1Measure from the inside top edge of the frame to the inside bottom edge
- 2Take measurements at left, center, and right sides
- 3Use the smallest measurement
Telescopic Advantage
SWB bars have telescopic height adjustment:
- • Model A: 35" to 65"
- • Model B: 35" to 61"
- • Model A/EXIT: 35" to 65"
As long as your height falls within this range, no exact measurement is needed— the bars adjust to fit!
Step 3: Check for Obstructions
Before ordering, note anything that might interfere with installation:
- Window handles/cranks: Ensure bars won't block operation
- Locks: Must remain accessible after bar installation
- Trim/molding: May need to be accounted for in measurements
- AC units: Seasonal units may require removable bars
- Window sensors: Alarm sensors shouldn't be blocked
Common Measurement Mistakes
Recording Your Measurements
Keep a record of each window you measure. Here's a simple format:
Which Model Do You Need?
| Your Height Range | Model A | Model B | Model A/EXIT |
|---|---|---|---|
| 35" - 61" | |||
| 61" - 65" | — | ||
| Bedroom (egress required) | — | — |
Ready to Order?
With your measurements in hand, you're ready to choose the right model. Remember: telescopic adjustment means you don't need perfect measurements!
