## Long description

The ABUS Door chain SK99 S B/DFNLI is a door security chain and lock designed for house and flat doors with narrow frame profiles. Made of hardened steel and finished in silver, the unit includes a door chain, a security ring that fits over the door handle after assembly, and a precision rotating locking mechanism that can only be opened from the inside. The mechanism contains a childproof safety catch and the product is supplied for mounting without drilling.
Advantages
The door chain is made of hardened steel for increased resistance against forced entry and features an internal childproof safety catch. A separate security ring provides an additional barrier and the rotating precision locking mechanism can only be released from the inside, improving privacy and safety. The product is supplied with a no-drill mounting option for easier installation and a slim design suitable for narrow door frames.
