How to identify the version of your patio door or window security bar
When providing support, we may ask you to identify the version of your 110, 111, or 112 security bar.
If you still have the original retail packaging
If you still have the original retail packaging, check the back near the UPC code.
On the right, in small writing, you should find a number beginning with "SK110" and ending with some letters after a hyphen / dash.
Tell us what letters appear after the hyphen.
If you no longer have the retail packaging
Or your bar came in plain shippable packaging
Check the end-cap at the free end of the bar for a recessed "C" indicator, as in this image.
Tell us if you have this feature or not.
