ABUS ABTS21540 Cadena de puerta con anilla de seguridad, acero niquelado, 215 mm

Secure your home with the ABUS ABTS21540 door chain, featuring a robust 215 mm nickel-plated steel chain and an integrated security ring (Überwurfring) that prevents the chain from being slipped off the lock when the door is ajar. This durable deterrent is ideal for inward-opening doors, offering basic security and peace of mind.

Overview

The ABUS ABTS21540 is a classic door chain designed to allow partial opening of the door while preventing unauthorized entry. The chain is made of hardened steel with a corrosion-resistant nickel-plated finish, ensuring long-lasting performance. The security ring is a key feature: it prevents the chain from being lifted off the lock pin, a common vulnerability in standard door chains. Installation is straightforward with the included mounting screws, and the two mounting plates (each 60 x 20 mm) provide a secure fit on both the door frame and door leaf.
