Measuring for your window insert:

To determine the correct range of window insert you need, open your sash window and measure from left to right inside the channel that the sash window travels up and down in. You want to measure into the deepest part of the channel since the window insert will expand due to the spring loaded end. Your measurement should be with the adjustment range chosen. You might notice that your measurement falls into two ranges, select the once that will allow soem room below and above your window width. This will allow the unit to compress enough to insert into your channel and still expand enough for a tight fit. You can always call us for personalized guidance to ensure your choice is correct.

Will These Insert fit all Sash Windows?

All Security Boss Window Insert will fit channels that are at least 1" wide.

Included Weather Stripping:

Every Security Boss Patio Insert features a replaceable bulb seal that lines both sides of the insert. This bulb seal provides a superior weather seal between the insert and the wall and sliding door. This weather seal can also be replaced if needed very easily by sliding the weatherstripping into the t-slot groove on your patio pet door.



The Weather Seal is a 3" wide vinyl weather stripping section that attaches to the back side of your sliding door. When an insert is installed, your sliding door breaks the seal between the slider and fixed panel. This weather stripping will seal out any drafts.

Adjustable Width Range:

You will notice that your Security Boss Window insert has a spring-loaded end that compresses and extends within a range of 3.25" This allows you to compress your unit to fit into the channel that you sash window travels and then extend so that the unit will fit tightly. The two easy turn locking knobs secure this end so that someone from the outside would not be able to gain entry.

 

How does my Sliding Door Lock?

We strongly suggest bracing the open sash window with a stick or an adjustable brace bar; as this immobilizes your slider and is the most effective way to secure your sliding door. We also offer several locking devices that can lock the open window to your frame via various bolt type locks.

Use of Extensions Ranges:

You can add 2 inch extensions to the top of all insert heights to extend their reach or adjustment range. These extensions snap into the top of your insert and fit tightly. No screws or hardware are required. It is possible to add more than two (2) extensions on the Security Boss Inserts. The snap in lock feature of the extensions allow for a stable firm unit regardless of the number of extensions are added.
