440-P Door Closer
440-P Size 4 Grade 2 Hydraulic Door Closer
The Cal-Royal 440-P Door Closer is a fixed size 4 hydraulic closer with a heavy-duty rack-and-pinion mechanism and separate closing and latching speed controls. The 440-P belongs to the 400 Series, described in the existing specifications as meeting or exceeding ANSI A156.4 Grade 2. Its non-handed construction and reinforced adjustable tube arm support compatible standard installations.
Practical Uses
Consider the 440-P for suitable commercial or residential doors where size 4 closing power matches the opening's requirements. It provides controlled door return without the adjustable spring-size range of a multi-size closer. Check door width, weight, mounting geometry, operating conditions, and required opening force before selecting it.
For replacement work, compare the existing closer's mounting pattern, arm arrangement, and operating requirements. A similar appearance or shared series designation does not guarantee a direct fit. Choose from the listed Alum, Duro, and Gold finishes to coordinate with surrounding hardware.
Installation and Replacement
Use the 440-P-specific instructions and template before marking or drilling. Confirm mounting clearances, required opening angle, arm position, fasteners, and mounting-surface suitability. The series description notes a streamlined design for many applications without adapters, but that is not a guarantee that every opening accepts the closer without additional preparation.
The 440-P is a sized closer: its separate regulating valves adjust closing and latching speeds, not spring size. Tune the main closing sweep and final latching portion according to the manufacturer's instructions. Stay within the adjustment limits and do not remove regulating valves.
After installation, test from several opening positions and confirm controlled closing and reliable latch engagement without excessive impact. Correct dragging hinges, binding seals, or strike misalignment before changing closer settings. Confirm supplied package contents and required mounting hardware before starting work.
Problems It Helps Address
- Uncontrolled door return: Hydraulic speed regulation helps control the closing cycle.
- Excessive impact near the latch: Separate latching-speed control allows adjustment of the final portion of travel.
- Worn size 4 hardware: Offers a replacement option where preparation and operating requirements match.
- Different door handing: Non-handed construction supports compatible left- and right-hand installations.
- Coordinating visible hardware: Three listed finishes offer appearance choices for the opening.
At a commercial or residential doorway, the door should return at a measured pace and latch behind the person passing through. The 440-P lets the installer tune the main closing sweep separately from the final latch portion. If size 4 power is not appropriate for the opening, speed adjustment does not turn it into a different spring-size model.

Model Selection and Optional Features
This listing is for 440-P, size 4. The broader series also includes 420-P, size 2, and 430-P and SM430-P, size 3. These are separate model designations, not selectable spring sizes in this listing.
The existing specifications list full cover and back-check as optional. Neither is established as included by this product's finish selections. Confirm the exact supplied configuration if either feature is required. Hold-open operation, delayed action, and adjustable spring power are not established as included.
Opening force and reliable latching: Check both on the complete installed opening. Do not infer accessibility compliance or fire-door suitability from the Grade 2 designation alone; verify the exact model documentation and project requirements.
