As an alternative to the "SF" model security fence, Journault Jourplex Inc. offers you a brand new security design to replace the conventional removable guardrail system. The integrated security fence, model ISF, consists of a rigid guardrail integrated inside an access hatch. When the access hatch is in the open position, the user can easily and quickly deploy each section of the fence to gain access to the opening in complete safety. Following its use, the operator disposes of the safety fence by compactly closing it on itself inside the access hatch.
