About the Pro-5 Duo Key Lockable Window Safety Lock

The Pro-5 Duo by Jackloc Window Safety Lock is a key locking window cable restrictor. It provides security against entry through windows and safety against falls, while still allowing the window to be opened up to 100mm.

The double locking system allows for the cable to removed from either side, or removed completely when not required.

The restrictor can fit most window and door sizes and types, including uPVC, Timber and Aluminium.

The Pro-5 Duo window safety lock is incredibly strong and suitable for domestic and commercial settings. It has a reinforced cable, security screws and heavy-weight body. Each Jackloc product is individually tested in the manufacturing process to hold a force of 3,600 newtons, exceeding all relevant standard requirements. The product comes with four hardened and zinc coated grade four security screws to prevent falls and help keep homes safe.

The key allows the window to be fully opened if required.

  • Standard cable length of 200mm
