Add to Cart:


  • Model: L6117
  • Brand: Evva
  • Condition: New


The EVVA OHZ keyed to differ oval half cylinder has a standard oval profile and is supplied complete with a connecting screw. The EVVA A5 system is a basic but robust 5-pin locking system and is available in many cylinder styles and with many optional special features.

Optional Special Features Available

Z - Cog Wheel Cams
Designed for use with multi-point locks or specialist mortice locks that are operated via a gear ring or a toothed rack, they can be supplied with 10, 13, 14 or 18 teeth instead of a standard cam.

CMK - Construction Keying
Cylinders installed during construction are operated by the "CMK Master Key". On completion of work the CMK is disabled by use of any Master Key or Differ Key. This removes the need to retrieve or keep track of any CMK Master Keys issued.

VAR - ABC Vario
3 sets of keys are provided, once key B is used then the A keys no longer work; when the C key is used then neither A nor B keys will no longer work.

PBP - Pre Determined Break Point
Cylinder will snap at a pre determined point to prevent entry via snapping, please note that this function is not TS007 rated.

TXT - Additional Numbering
Specific numbering or sequential numbering on keys to allow the end user to keep track of issued keys and highlight losses.

SEW - Sea Water Protections
For cylinders that are exposed to more severe environmental influences, corrosion-susceptible cylinder parts are supplied with a special surface treatment; this comes as standard for Aldridge cylinders.

SG-A - Bump Resistant
Provides protected against access via a specially milled bump key by using separated body pins.

FLEX - Adapted Entry
One or both sides of the cylinder can be operated via Square, Triangle, Hexagon or slot feature, e.g. one side could be opened with a key and the other by an 8mm socket.

ARS - Plug Pulling Protection
A special nickel silver cam connects to the plugs on both sides to protect from plug pulling attempts.

KZS - Plug Pulling Protection
Carbide components in the plug protect against plug pulling attempts.
