Paw-Lock for interior French doors. Just slide over the door knobs of a set of French doors and keep those pesky animals from opening them up. Customizable to various dimensions, including but not limited to the listed sizes. Each size has a built in tolerance of approximately 1/4" around each knob post. The measurement I need is center of one door knob to the center of the other. The design assumes 1" posts behind the knob and about 1/2" clearance between the knob and the door for the lock to slide behind the knob. If your posts are smaller than 1" please let me know. Perfect for limiting accessibility to any room with French doors, including pets. Your knob center size not listed? Select custom and in the personalization specify the distance between the door knob centers. Even if your size is listed you can customize the text or request no writing/text. The default text is PAW - LOCK. There is also a place for buyers notes to add any detail you believe is necessary. Those notes follow the lock through production. If you have questions feel free to reach out via Etsy message.
