  • CLSTT Tandem Full Height Turnstile

    The CLSTT tandem full height turnstile includes all the same core features as our other tandem models, but adds crystal clear side panels to provide a more aesthetic appearance. Simply put, no other tandem full height product comes close to the quality, looks and performance of the CLSTT.

    Secured entry control applications

    Perimeter control   |   Employee and visitor access control   |   Time and attendance integration   |   Fence line security   |   Parking lot access   |   One way exit control   |   Unattended entry points

    Designed to last

    Superior Construction

    The CLSTT tandem full height maximum security turnstile cuts no corners. Unlike competitive models that use individual parts that must be bolted together during installation, the integral sections of the CLSTT are delivered fully welded, creating a solid, secure and structurally sound product. The clear side panels in aluminum frames enhance the appearance and improve sight lines. Details matter, especially when manufacturing a tandem full height security turnstile to stand the test of time.

    The CLSTT’s tandem space saving design requires approximately 30″ less end to end installation space than two individual turnstiles installed side by side.

    Key Features:

    Crystal clear side panels in aluminum frames

    Compact installation footprint

    Welded steel construction with no exposed bolts or fasteners

    Stainless steel top channel cover and internal parts

    High quality sealed and covered bearings

    Splined connection between the rotating section and  top channel assembly provides a precision fit that minimizes play

    Dozens of options and several finishes available

    Added Benefits:

    Fit two turnstiles in more confined areas

    Better sight lines and more aesthetic look

    Easy to install and easy to maintain


    Ready to meet your security needs

    Unsurpassed Facility Entrance Control

    The  CLSTT features electric lock control, and is richly appointed with standard features that are expensive options on competitor products.

    It provides bi-directional access control in conjunction with a facility access control system or any device that can provide a dry contact output (such as a push button). The turnstile comes with attachment points for card readers and each passage direction can be configured as either fail-safe or fail-lock. In operation, when a valid credential is presented, the turnstile unlocks, allowing a single controlled rotation in the requested direction. Unauthorized entries, or attempts to tailgate on an authorized entry, are deterred.

    The CLSTT has built in override controls that provide additional flexibility. Passage directions can be set for free passage, controlled passage or locked down.

    Key Features:

    Single or bi-directional control

    Electric lock control

    Independent fail-safe or fail-secure operation

    Speed control to provide a controlled, safe rotation

    Automatic self-centering prevents over or under travel of rotating section

    Built-in override controls

    Rugged turnstile controller integrates with any access control system

    Low maintenance

    Added Benefits:

    Secure and safe

    Intuitive for users and staff

    Integrates easily with access control systems

    Can be operated in unattended applications

    Controlled rotation minimizes physical abuse, banging and wear on components

    Simple to change between fail-safe and fail-lock operation

    Simplified integration

    Access Control and Visitor Management

    Integrating the CLSTT tandem full height electric turnstile into your facility is quick and easy. It integrates with virtually any access control or visitor management system and accommodates a wide array of credential readers. A dedicated fire system input is provided and passage outputs can be monitored to validate passage after activation, or to provide accurate people counting. The result is a full height security product that thousands of facilities worldwide rely upon for superior access control and visitor management.

    Key Features:

    Simplified integration to access control and visitor management systems

    Flexible credential reader attachment options allows use of existing readers familiar to users

    Dedicated fire input and various other available I/O

    Safety features you shouldn’t be without

    Built-in Safety

    CLSTT tandem full height turnstiles provide secure and safe operation. Built in speed control self-adjusts to the pushing force of the user. Even when a user pushes hard on the turnstile arms, the speed of rotation is controlled. This increases safety and reduces the chance of a rapidly spinning rotating section catching a user’s heel. In addition to controlling the rotation speed, Alvarado’s speed control also greatly reduces kickback of the rotating sections toward the user when the turnstiles relock. After each passage, the rotating sections smoothly returns to the home position and locks in place, ready for the next user. The unique cam design of the CLSTT also makes it mechanically impossible for a user to get locked inside the turnstile.

    In secured applications the CLSTT is typically configured for fail-lock in the entrance direction and fail-safe in the exit direction. When power is removed from the turnstile this prevents people from entering but allows personnel to exit. Turnstiles configured for fail-lock in the exit direction can also provide free egress using local key override controls. Other ordering options are available and changing between fail-lock and fail-safe is easily accomplished in the field. A dedicated input for fire systems also provides free egress in the event of emergencies.

    All weather arm and heel pads are available to slip over select arms on the rotating section for additional safety.

    Key Features:

    Speed control provides a safe, controlled rotation and smoothly self-centers rotating arms

    Self-centering mechanism to prevent entrapment

    Free egress in emergencies or loss of power

    Splined rotary to ensure correct installation

    Optional heel / arm guards for rotary


    The CLSTT full height security turnstile is independently tested and certified by LA Testing Labs. It is also CE marked.
