I do not think the pull down handles will work with the bear claws but I have never looked at their function to confirm this. If you have the push button handles it will work fine. See my write up I posted previously to your initial thread on this subject.

If you have the pull down handles you may have to analyze how they operate to see if a way to activate the latch can be fabricated. None of these are true plug and play systems. You will have to "make" it work unless you plan to use door poppers.

As for security I am using the push forward feature of the inside door handle to lock my doors. Works just fine.
