Customer Questions & Answers

  • Question: What are the key features of the Dorma RTS88-105-NHO-3 Overhead Concealed Door Closer?

    Answer: The Dorma RTS88-105-NHO-3 features a non-hold open function, making it ideal for maintaining smooth door operations in commercial and residential environments. It is specifically designed for overhead concealed installation, ensuring a clean aesthetic without visible hardware. The size 3 body accommodates doors weighing between 75 and 110 pounds, allowing for versatility in various applications such as office spaces, retail shops, and hotels. The efficient hydraulic mechanism ensures consistent closing speeds to minimize slams, making it suitable for high-traffic areas.
  • Question: How do I install the Dorma RTS88-105-NHO-3 door closer?

    Answer: Installation of the Dorma RTS88-105-NHO-3 requires proper planning and basic tools. Typical installation involves mounting the closer inside the door frame, with attention to alignment and height specifications. It's recommended to consult the product manual for specific instructions and details on drilling patterns. For optimal performance, ensure that the door and frame are square and free from obstructions. This door closer is ideal for applications in schools and hospitals where door performance is paramount for safety.
  • Question: What is the difference between a non-hold open and a hold open door closer?

    Answer: A non-hold open door closer, like the Dorma RTS88-105-NHO-3, allows the door to close smoothly after being opened, but doesn’t keep it in an open position. This is beneficial for ensuring the door remains closed when not in use, enhancing security and privacy. In contrast, a hold open door closer retains the door in an open state until manually closed. Non-hold open models are suitable for locations where door movement or constant closure is necessary, such as fire-rated doors in commercial buildings.
  • Question: What applications are best suited for the Dorma RTS88-105-NHO-3?

    Answer: The Dorma RTS88-105-NHO-3 is ideal for a variety of applications, particularly in environments requiring discreet door hardware, such as offices, hospitals, and educational institutions. The concealed design not only enhances aesthetic appeal but also provides functional benefits, ensuring the door operates silently. High-traffic areas benefit from the door closer's durability and reliability, making it a perfect choice for both interior and exterior doors that require consistent operational integrity.
  • Question: Can the Dorma RTS88-105-NHO-3 be used on all types of doors?

    Answer: The Dorma RTS88-105-NHO-3 is designed for use with medium weight doors and is generally compatible with standard wooden and metal doors. Its functionality is best realized when installed on doors weighing between 75 and 110 pounds. It’s not recommended for very lightweight or very heavy doors, as this could affect performance and longevity. In settings such as shopping malls or office buildings, it provides effective closure while maintaining a modern look in various door designs.
  • Question: What are the closing speed adjustments available with this door closer?

    Answer: The Dorma RTS88-105-NHO-3 allows for closing speed adjustments, which can be tailored to meet specific needs. Users can adjust the low-speed and latch-speed to create a smoother closing experience, reducing the risk of door slamming. These adjustments make it suitable for environments like hospitals where patient safety is paramount. The level of customization offered ensures that the door behaves as desired, accommodating different user scenarios and preferences.
  • Question: Is maintenance required for the Dorma RTS88-105-NHO-3?

    Answer: Routine maintenance of the Dorma RTS88-105-NHO-3 is minimal but essential for optimal performance. Regularly check for any signs of wear, and ensure that the closer is properly lubricated to avoid squeaking or stiff operation. In environments such as schools or offices, periodic checks help maintain functionality, ensuring doors close correctly without interruptions. Keeping the closer clean and free from debris will also prolong its lifespan and reliability.
  • Question: What is the installation height recommended for the Dorma RTS88-105-NHO-3?

    Answer: For optimal functionality, the Dorma RTS88-105-NHO-3 should ideally be installed at a height of 40 to 42 inches from the finished floor to the centerline of the closer. This standard positioning ensures effective door operation and accessibility, particularly for users of different heights. It is especially important in public buildings, where universal access is mandated, making it crucial for compliance with safety and accessibility standards.
  • Question: Can this door closer be adjusted for different door weights?

    Answer: While the Dorma RTS88-105-NHO-3 is categorized for medium-weight doors between 75 to 110 pounds, it allows for some adjustment in closing speeds and forces to cater to slightly different weights. However, for doors outside this range, it’s advisable to select a closer specifically rated for that weight class for optimal performance. Scenarios in commercial spaces, such as office doors or conference rooms, benefit greatly from the door closer's adaptability in different settings.
  • Question: Where can I buy the Dorma RTS88-105-NHO-3 Non Hold Open 105 Overhead Concealed Door Closer Size 3 Body Only?

    Answer: You can buy the Dorma RTS88-105-NHO-3 Non Hold Open 105 Overhead Concealed Door Closer Size 3 Body Only from Ubuy in UK.
