CompX National DualAxess® Cam Lock

D803

DualAxess can be retrofit for existing wood or metal applications to give keyless access and to eliminate keys. The lock can be mounted vertically or horizontally on flush, overlay or lipped/overlay applications. Attach the cam for 90° latching in any direction, based on individual application needs.

To change the combination, the current combination and a valid key is needed. 10,000 possible combinations - any four digit number - are available.

DualAxess by CompX can be operated using either a combination or a key. Once unlocked, rotate the housing 90° clockwise to unlatch.
