Defender Security U 10304 Chain Door Guard – Door Chain Lock for Door and Home Security, 3-5/16”, Solid Brass Construction with a Satin Nickel Finish

Buena calidad y resistencia del material de la cadena.

Os parafusos são maiores do que os buracos , tive que comprar parafusos novos

This is great if you have small kids who love to run outside without permission. We mounted them up high so the kids could not open the door (much). This far has held up well.

I purchased this item as an additional barrier of door protection as well as preventing my younger child from unlocking the doors and going outside. Works well, does the job I needed it to do and install was simple. Price point for 2 units is also affordable and efficient. Good 2 go.

This lock is highly durable and very simple to install. Highly recommend!
