TRAPPED KEY INTERLOCKS LIMITED

Trapped Key Interlocks Ltd. is the authorised Irish distributor for Castell Safety International, the world‑renowned developer of trapped‑key interlocking technology since 1922. Drawing on the legacy of Stewart Andrews Engineering Ltd., the company supplies robust safety devices that lock or release movable parts only when a preceding component is securely positioned, thereby enforcing the correct sequence of operations and protecting both personnel and plant.

The core offering centres on a complete range of Castell trapped‑key interlock systems, which can be mounted directly onto equipment across the energy, industrial and logistics sectors. These solutions provide physical risk control that goes beyond traditional lock‑out/tag‑out methods, preventing accidental or unauthorised movements, reducing equipment damage and ensuring compliance with health‑and‑safety regulations. Trapped Key Interlocks Ltd. works closely with customers to design, install and maintain integrated interlocking solutions that are simple to operate yet uncompromising in safety.

Based in Dublin, the company serves organisations throughout the Republic of Ireland that require reliable, sequence‑controlled safety systems for harsh or safety‑critical environments. Their commitment to integrity, knowledge and long‑standing relationships makes them a trusted partner for any operation where safety cannot be compromised.
