The design of the ULTION WXM has been evolved with a new two-part plug that has increased engagement with a new curved cap, as well as the entire section now being moulded from molybdenum and not brass.
Brisant says this strengthening is then coupled with the thicker WXM key shape and composition. Improved drill protection has also been delivered and it still houses 20 anti-drill points, but the clutch is shielded with the molybdenum section of the plug. There are also now two locking pins, which fire into the body of the attack pin rather than across it. All the pins used in this area of the lock are made from hardened stainless steel 630.
The thicker key has also enabled the Brisant team to remove the five passive top pins and introduce two additional pin lengths to lower the active pins, whilst concurrently increasing the apex differentials between the heights, making the lock harder to pick. The new pin heights produce in excess of 260,000 working differs, more than doubling the maximum requirement for the TS007 3 Star grade 6.
