Shutter padlocks – also known as straight shackle padlocks - are characterised by a rectangular, U-shaped body, with a sliding bolt to close the loop across the forks. They were designed specifically for attaching to hasps on rolling or sliding shutters where access to the lock may be difficult due to being close to the ground. Armoured models are available for increased security and there are many versions offering British Standard compliance and good level CEN ratings. Straight shackles generally resist sawing by rolling in situ, whilst the body shape makes attack by bolt cutters difficult.
Amongst the many designs available, the Viro Mini Condor is especially well suited as a shutter padlock, as it features an extra thick 23mm shackle, floor fixing device, hardened cylinder, and an armoured, drill resistant case. Armoured models are also produced by Ifam, Abus, and ezlok. easylocks can supply a wide range of shutter padlocks from leading manufacturers, with a number of keying options and security levels for different applications.
