A hydraulic door closer is a frequently utilized component, particularly on storm doors, designed to control door speed—preventing both excessively fast opening and closing. Damage to a hydraulic door closer can lead to rapid door closure, potentially resulting in broken glass and the need for complete door replacement. Installation or replacement of these closers is a manageable task, and this article details the process based on available documentation.
Understanding Hydraulic Door Closers
The primary function of a hydraulic door closer is to regulate the speed at which a door opens and closes. This prevents slamming, which can damage the door, frame, or surrounding objects. According to available resources, these devices are “arguably the most important part of the door,” especially on storm doors. A malfunctioning closer can lead to damage, making timely replacement or repair crucial.
Purchasing a Hydraulic Door Closer
When selecting a hydraulic door closer, determining the correct size is important. The documentation suggests measuring the width of the door using a tape measure. If a closer is already installed, extending it fully and measuring its length can also provide the necessary information. Consulting with a hardware store clerk can further assist in choosing the appropriate model.
Removing an Existing Door Closer
Prior to removing an existing door closer, it is essential to secure the door to prevent accidental closure and potential injury. The documentation emphasizes propping the door open during this process. The removal process involves locating and removing the screws on both ends of the closer using a screwdriver. Once all screws are removed, the hydraulic door closer should detach from both the door and the door jamb.
Replacing a Door Closer
Replacing a door closer is generally simpler than installing one on a door that previously lacked one. The new hydraulic door closer is positioned on the jamb, aligning the screw holes. Screws are then inserted and tightened slightly. The other end of the closer is aligned with the screw holes on the door, and screws are inserted and tightened, alternating between sides to ensure even distribution of pressure.
Installing a New Door Closer
Installing a hydraulic door closer on a door that did not previously have one requires additional preparation. This includes drilling pilot holes. The documentation specifies using a drill bit smaller in diameter than the screws to be used. It is crucial to consult the specific instructions accompanying the closer, as designs vary between manufacturers and models. To mark the drill locations, the closer should be held in place, and the screw hole locations marked with a marker. Pilot holes are then drilled through each marked location. Following this, the new hydraulic door closer can be installed using the steps outlined in the “Replacing a Door Closer” section.
Mounting Considerations and Hardware
The documentation references the potential need for a mounting plate in certain applications. Additionally, a longer connecting rod may be required if the reveal—the gap between the door and the frame—exceeds 3 inches (76mm). The documentation also notes the availability of self-drilling screws for wood and metal applications, specifying drill bit and tap sizes for machine screws (#7 drill, 1/4"-20 tap).
Door and Frame Preparation
Proper door and frame reinforcement is essential for a successful installation. The documentation emphasizes that doors and frames must be adequately reinforced to support the closer. It also notes that the dimensions provided in the installation instructions are based on standard doors and frames with specific clearances (1/8 inch), stop dimensions (5/8 inch), and door edges (square).
Important Safety and Code Considerations
The documentation includes a cautionary note regarding the potential for property damage or personal injury due to incorrect installation or adjustment. It stresses the importance of following the installation instructions carefully. Furthermore, it advises checking local building and fire codes to determine if the use of sleeve nuts and bolts is required for the specific application.
Component Parts Identification
The documentation provides a labeled diagram identifying the various components of a Hager 5100 Series door closer. These components include the backcheck valve, closer body, parallel arm bracket, power adjustment shaft, regular arm/top jamb shoe, connecting rod, insert cutouts, cover insert, forearm, screws, main arm, closer arm, closer cover, latch valve, and sweep valve. The documentation also lists the tools required for installation, including drill bits for wood (3/16 inch) and metal (9/32 inch) and a tap size of 1/4"-20 for machine screws.
Arm Types and Installation Pages
The documentation differentiates between regular arm and parallel arm installations, directing users to specific pages within the installation sheet for each type. It also addresses different door handings (left hand, right hand, left hand reverse, right hand reverse) and their corresponding installation procedures. Specific attention is given to top jamb applications, with a note indicating that a separate door and frame preparation template may be required.
Additional Hardware Options
Component Hardware Group, Inc. offers a wide range of related hardware components, including valves, walk-in refrigeration hardware, outdoor walk-in hardware, stainless steel hardware, cabinet hardware, drawer assemblies, locks, sliding door hardware, cafeteria components, and access doors. This suggests a comprehensive offering for various door and hardware needs.
Non-Handed Door Closer Limitations
The documentation explicitly states that non-handed door closers should not be installed on the exterior (weather) side of exterior doors. This limitation is important to consider when selecting and installing a door closer.
Conclusion
Installing or replacing a hydraulic door closer is a relatively straightforward process, provided the correct tools and instructions are followed. Proper preparation, including accurate measurements, secure door support during removal, and adherence to safety guidelines, are crucial for a successful installation. Consulting the manufacturer’s instructions and local building codes is also recommended. The documentation highlights the importance of these devices in preventing door damage and ensuring safe operation.
