Lockking Security Lock Bars for Sliding Glass Doors with Pet Door Panels

Another version of Lockking Security Lock Bar is for Pet Door Panels.

These locks are the same as the commercial version but with a varying size range to correspond with your Pet Panel. 

The lock bar can apply pressure to the sliding door thus applying pressure to the Pet Door Panel helping to seal it.  Aligning the sliding door with the panel may be necessary. 

The Stoplock comes into play when installing a Pet Door Panel.  The manufacturers seal between the two glass panels is broken creating a draft, most pet door manufacturers supply a weatherstrip to solve this problem. 

But there is another problem, a wire can be used to tamper with the lock. That is remedied by using a Stoplock which helps secure the lock bar.
