E3 Union & Fortress Decoder.
- The E3 Decoder is a simple and effective tool to decode the ERA Fortress and Union Strongbolt. The system works by decoding each of the levers in turn and then using a make-up key to open the lock.
- This system works on the old ?hidden curtain? ERA Fortress as well as the new one. It also decodes and opens the Union Strongbolt.
- Unlike other systems this one is not restricted in its use by the lock?s warding. The lever next to the cap can be read as easily as the others.
- Manufactured in the UK.
