The ISEO 52N015 is part of ISEO's Serie 5 range, an electric rim lock built specifically for pedestrian gates and the main entrance doors of residential buildings. It's fully reversible for right- or left-handed installation, so installers can invert the same lock with a few quick setting changes rather than stocking separate left- and right-hand versions, a genuine time-saver for jobs they haven't seen yet.

The backset is adjustable to 50, 60, 70, or 80mm, so it fits a wide range of existing gate and door preparations without needing a completely new install. It's a multifunction lock too: from the inside, you can choose to open with key only, key and button, or button only, letting one lock serve different access-control setups depending on the building.

ISEO built the 52N015 to be genuinely universal, supplied with the accessories needed to install it on both wooden gates and steel main entrance doors, and the lock case and strike are made from pressed steel with anti-corrosion treatment, so it holds up to years of outdoor exposure on a gate that's opened multiple times a day. It comes standard with a 5-pin brass cylinder and three flat nickel-plated brass keys, and it connects to a standard low-voltage supply, making it straightforward to wire into an intercom or gate entry system.
