Canister Swivel Connector "SMK" for NBC - Masks

The use of optical equipment, such as guns or binoculars, with an NBC mask with a centre filter is always a problem.

Our jointless knee allows the bearer to swing the filter to the right or left without disconnecting it, and it will stay in the decided position.

  • 100% tight while swinging!
  • No reduction of the airflow!
  • The weight of the filter remains centred within the mask.
  • It is always possible to change the position of the filter.
  • Fits any mask with a NATO-standard thread.
