300PBFCOV Interior Barrier-Free Adjustable Door Closer with Full Cover
The Cal-Royal 300PBFCOV Door Closer is a non-handed hydraulic closer for compatible interior doors requiring adjustable closing control. The 300PBFCOV offers fully adjustable sizes 1–4, separate closing and latching speed valves, standard adjustable back-check, and a full plastic cover. Its listed door-weight range is 30–185 lb, subject to the opening and mounting requirements.
Practical Uses
Consider the 300PBFCOV for suitable interior office, retail, hospitality, and institutional doors where a barrier-free closer application is specified. Adjustable spring sizing allows the installer to tune closing power for the actual opening rather than relying on a fixed-size closer.
It is also a replacement option for compatible existing installations. Compare the mounting pattern, arm arrangement, door and frame clearances, and operating requirements before assuming that existing holes or brackets can be reused. Choose from Alum, Duro, Gold, and US3 bright brass to coordinate with the surrounding hardware.
Installation and Replacement
Use the instructions and template for the chosen mounting arrangement: regular arm on the pull side, top jamb on the push side, or parallel arm on the push side. Confirm the required arm, bracket, fasteners, opening clearance, and mounting surface before marking or drilling. The existing specifications identify standard size #4 mounting holes with a 9-1/16" reference; compare the complete template rather than relying on this measurement alone.
Set spring power within the 1–4 range for the actual door and application. Adjust closing speed and final latching speed with their separate regulating valves, following the manufacturer's adjustment limits. Set back-check for the opening conditions; it is not a substitute for a suitable door stop.
After installation, test the door from several opening positions. Verify controlled travel and reliable latching without excessive impact. If the door drags or binds, correct alignment, hinges, seals, or latch issues before using closer adjustment to compensate.
Problems It Helps Address
- Closing too quickly: Adjustable hydraulic closing speed helps tune the main closing cycle.
- Inconsistent final latching: Separate latch-speed control and adjustable spring power support setup for a properly aligned opening.
- Rapid opening: Standard adjustable back-check provides opening resistance within the manufacturer's operating range.
- Different installation conditions: Non-handed construction supports standard mounting arrangements with the appropriate hardware and template.
- Worn interior door closers: Provides a replacement option where the mounting and operating requirements match.
At an interior office doorway, a well-adjusted closer lets the door return at a measured pace and engage the latch behind the person passing through. The 300PBFCOV's separate speed controls give the installer a way to tune the main sweep and final latch portion independently, while checking that the opening remains usable.

Model Selection and Operating Considerations
300PBFCOV is not the same sizing as 300PCOV. The broader series includes a 300PCOV model adjustable through sizes 3–6 for a listed 85–260 lb door-weight range. Those heavier-model specifications do not apply to this 300PBFCOV listing.
The existing series description mentions optional adjustable delayed action. This listing has finish selections only, so delayed action is not established as included. Confirm the exact configuration and package contents if a special arm, bracket, or delayed-action feature is required. Hold-open accessories are not established as included.
Barrier-free setup: Reduced opening force must be balanced with sufficient power to close and latch the actual door. Verify operating force, clearances, and reliable latching on the complete installed opening. The model designation alone does not establish accessibility compliance for every installation.
