Deadlocks: Detainer

Detainer deadlocks, formerly renowned under the Chubb C-Series banner, offer exceptionally robust security for external timber doors. Utilising a highly sophisticated detainer mechanism rather than standard levers, these heavy-duty mortice deadlocks provide superior resistance against picking, drilling, and forced entry. Ideal for both commercial and domestic properties, many of these high-security locks are fire-rated for timber doors and feature tens of thousands of key differs to prevent unauthorised duplication, making them an industry-standard choice for premium physical security.
