CR441 Adjustable Size 1–6 Grade 1 Door Closer
The Cal-Royal CR441 Door Closer is a heavy-duty hydraulic closer for compatible commercial and institutional doors. Its adjustable size 1–6 spring power, separate closing and latching speed controls, and standard adjustable back-check allow the closer to be set for the opening. The CR441 is non-handed and supports standard, top jamb, or parallel arm installation with the appropriate preparation.
Practical Uses
Consider the CR441 for suitable doors in commercial buildings, schools, universities, healthcare facilities, government offices, retail spaces, and hospitality properties. It is a replacement option where the mounting pattern, door and frame geometry, arm arrangement, and required closing power are compatible.
The full plastic cover provides a finished appearance over the closer body. Seven listed finish choices help coordinate the closer with the surrounding door hardware without changing the basic closer selection.
Installation and Replacement
Choose the mounting arrangement before marking holes: standard, top jamb, and parallel arm installations have separate templates. Check door width and weight, frame clearances, arm clearance, opening angle, and the mounting surface against the manufacturer's instructions. The listed door-weight range is 30–260 lb, but weight alone does not establish suitability for every opening.
The closer is factory preset to size 3 and adjustable through sizes 1–6. Set spring power for the actual opening, then adjust closing and latching speeds using their separate regulating valves. Follow the instructions for back-check adjustment; back-check controls opening resistance and should not be treated as a substitute for an appropriate door stop.
The existing listing identifies a parallel arm bracket, wood screws, sex bolts, and machine screws in the installation kit, along with self-tapping screws and a closer adjustment gauge. Confirm the supplied fasteners suit the door and frame construction. After installation, test from several opening positions and verify that the door closes and latches reliably without excessive impact.
Problems It Helps Address
- Uncontrolled closing speed: Separate closing and latching adjustments help tune the closing cycle.
- Inconsistent final latching: Adjustable spring power and latch speed support setup for the opening when the door, hinges, and latch are properly aligned.
- Rapid opening: Standard adjustable back-check provides opening resistance within the manufacturer's operating range.
- Different mounting conditions: Non-handed construction supports standard, top jamb, and parallel arm arrangements with the correct template.
- Worn commercial closers: Grade 1 construction offers a replacement option where mounting and operating requirements match.
At a busy office or school doorway, people should be able to pass through while the door returns at a controlled pace and latches behind them. If it closes too quickly or stops short of the latch, inspect the complete opening and adjust the CR441 according to its instructions rather than simply increasing spring power to overcome a binding door.

Optional Delayed Action
CR441 DA is the optional delayed-action configuration, not a selectable option shown in this listing. The existing series information describes an approximately 20-second factory delay between 70° and 0°, adjustable up to one minute. Confirm the exact delayed-action model and its operating settings before ordering if this feature is required. Delayed action should not be confused with a hold-open function.
Opening Force and Reliable Latching
Important: A closer selected, installed, and adjusted for ADA or other reduced-opening-force requirements may not provide sufficient power to close and latch the door. Door location and operating conditions can also affect closer performance. Check opening force and reliable closing together on the complete installed opening rather than assuming that the closer alone establishes accessibility.
The existing listing describes the CR441 as UL listed for fire-door use. Verify the selected closer, mounting arrangement, and any accessories against the requirements of the complete labeled assembly. Optional hold-open arms and specialized accessories are not established as included with this listing.
