Circlelock Combi Interlocking High Security Portal

A Half Security Portal for Existing Doors

The Circlelock Combi is a cylindrical mantrap portal solution that has a single sliding door on one end and an opening on the other end that is mounted to an existing swing door. This unique half portal solution prevents unauthorized entry into high security areas already using fire-rated swinging doors, while saving on space and renovation costs.

A Half Portal with Security & Safety Capabilities

The Circlelock Combi is a space-saving half security portal for applications where high security is desired, but space and time for building reconstruction are a concern. The Combi can be attached to a swing door to increase fire safety and security on either the secure or non-secure side of the building. By turning a swing door into a mantrap portal solution, facilities can prevent piggybacking 24/7 and eliminate the need for manned supervision.

Suggested Segments

  • Data centers
  • Financial
  • Insurance
  • Medical / pharmaceutical
  • Government / military
  • Casinos

High Security Solutions for all Building Types

A half portal installation is cost-effective and can be implemented in a timely manner. On authorization, the sliding door of the portal opens, allowing a user to enter the Combi. An integrated security system, StereoVision 2, confirms the user is alone and the swing door unlocks, allowing the user to pass into the secure area. A secondary biometric system such as facial recognition (by others) can be used to confirm identity inside the portal, supporting two- or multi-factor authentication.

Level Up on Security Features

The Circlelock Combi comes with a number of possible security options ranging from two-way piggybacking detection up to multi-factor authentication. Our StereoVision 2 anti-piggybacking system is the most sophisticated on the market and can accurately detect and prevent two users from entering the portal on a single authorized credential. The Combi comes standard with one-way StereoVision 2 to detect piggybacking as users enter the secure area. Organizations looking to increase the security level of the Combi can also consider the following features:

  1. Two-way StereoVision 2: with optional two-way StereoVision 2, organizsations can provide additional advanced piggybacking prevention when users exit the secure area (in addition to entry).
  2. Internal biometric post: allows for mounting of an internal biometric device (by others) for two- or multi-factor authentication capabilities. This ensures that the person who presents credentials outside the portal is the same person who is inside.
  3. Bullet-Resistant Package: Bullet-resistant glass (BR3) in the sidewalls and sliding doorset along with reinforced steel endposts can buy users precious seconds to enter the secure side and flee to safety during an active shooter incident.


The Circlelock Combi complies with the following European standards:

  • UL 325 & 2593
  • CSA 22.2#247
