SM430-P Door Closer
SM430-P Size 3 Grade 2 Hydraulic Door Closer
The Cal-Royal SM430-P Door Closer is a fixed size 3 hydraulic closer with a heavy-duty rack-and-pinion mechanism and separate closing and latching speed controls. The SM430-P belongs to the 400 Series, described in the existing specifications as meeting or exceeding ANSI A156.4 Grade 2. This listing offers the Alum finish.
Practical Uses
Consider the SM430-P for compatible commercial or residential openings where size 3 closing power and its model-specific preparation suit the door. Its non-handed design supports compatible left- and right-hand installations. Check door width, weight, mounting geometry, operating conditions, and opening-force requirements before selecting it.
For replacement work, identify the exact existing closer and compare the full template before reusing mounting holes. The SM430-P and 430-P are both described as size 3 models, but that does not establish identical dimensions, preparation, or interchangeability.
Installation and Replacement
Use the SM430-P-specific instructions and template before marking or drilling. Check arm position, opening clearance, required fasteners, and mounting-surface suitability for the actual door and frame. The series description notes a streamlined design for many installations without adapters; verify the opening rather than assuming an adapter-free replacement.
The SM430-P is a sized closer, not a multi-size adjustable-spring model. Its separate regulating valves adjust the main closing sweep and final latching speed, not the spring size. Follow the manufacturer's adjustment limits and do not remove regulating valves.
After installation, test from several opening positions and verify controlled closing and reliable latch engagement without excessive impact. If the door drags, binds, or stops short of latching, inspect hinges, seals, strike alignment, and closer preparation before changing settings. Confirm the supplied package contents and required installation hardware before starting work.
Problems It Helps Address
- Uncontrolled door return: Hydraulic regulation helps control closing speed.
- Excessive impact near the latch: Separate latching-speed control allows the final portion of travel to be adjusted independently.
- Worn SM430-P hardware: Offers a replacement option where preparation and operating requirements match.
- Different door handing: Non-handed construction supports compatible left- and right-hand openings.
- Confusion between series models: A dedicated SM430-P template helps distinguish its preparation from other 400 Series closers.
At an office or residential doorway, the door should return at a measured pace and engage the latch behind the person passing through. The SM430-P lets the installer tune the closing sweep separately from the final latch portion. If size 3 power is not appropriate for the opening, speed adjustment cannot turn the closer into a different spring-size model.

Model Selection and Optional Features
This listing is for SM430-P, size 3. The broader series also includes 420-P, size 2, 430-P, size 3, and 440-P, size 4. 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 the Alum finish selection. 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.
