Cal-Royal 300PBFCOV-DURO – Frequently Asked Questions

1) Will one Cal-Royal 300PBFCOV door closer cover different door weights, or do I have to order a specific size?
One unit covers the range. The 300PBFCOV is non-sized and fully adjustable from size 1 through 4, handling doors from 30 to 185 lbs, so a property manager can stock a single closer for interior offices, corridors and heavier entry doors and dial in the spring size on site. That is what makes it practical for standardizing across a building instead of carrying four fixed-size closers.
2) Do I need to know the door handing before ordering the Cal-Royal 300PBFCOV closer?
No. The 300PBFCOV is a non-handed, universal closer, so the same unit works on left hand and right hand doors. One part number covers every opening on the job, which cuts down what you have to keep on the truck.
3) Will the Cal-Royal 300PBFCOV line up with the mounting holes from the closer I am taking off?
It uses a universal mounting pattern with standard size #4 mounting holes spaced 9-1/16 inches apart, which is the common commercial pattern, so on many retrofits it drops onto existing prep without re-drilling the door. Measure the hole spacing on the old closer before you pull it: if it is 9-1/16 inch centers on a #4 pattern, you are lined up.
4) Does the Cal-Royal 300PBFCOV meet ADA opening force requirements for a barrier free door?
It is built for ADA Barrier Free applications, and the adjustable range from size 1 up is what lets you set the spring low enough to bring opening force down on an accessible interior opening. An optional adjustable delayed action is also available, which holds the door open longer so someone using a walker or wheelchair can clear the doorway.
5) Is the Cal-Royal 300PBFCOV closer rated Grade 1 for a school or hospital corridor?
Factory tested to meet or exceed ANSI/BHMA A156.4 Grade 1, so it qualifies for the commercial-grade spec an institutional buyer is usually working to. Cal-Royal lists it for office and retail, hotels, healthcare, educational and industrial buildings, in both new construction and renovation work.
6) The door is too heavy for a 185 lb surface closer - what should I use instead?
The Cal-Royal 300PBFCOV is adjustable through sizes 1 to 4 for doors weighing 30 to 185 lbs, so a heavier leaf needs a different closer type. Norton Rixson offers heavy duty center hung floor closers with higher capacities: the 28 Series single acting is rated to 350 lbs door weight, the 328 Series single acting to 325 lbs, and the 40 Series center hung floor closer with cement case to 300 lbs. All three are Grade 1, heavy duty, and are floor closers requiring a cement case or floor prep rather than the 300PBFCOV's surface mounting on a 9-1/16 inch hole pattern.
7) Can I use a Cal-Royal 300PBFCOV on a double acting door?
The 300PBFCOV is a surface mounted hydraulic closer with a universal, non-handed mounting pattern intended for standard commercial swing doors, and it controls the door in one direction of swing. For a double acting opening, the Norton Rixson 30 Series is a center hung double acting heavy duty floor closer rated to 200 lbs door weight, Grade 1, and it is set into the floor rather than mounted on the door or frame.
8) Does the Cal-Royal 300PBFCOV come with a cover, and how big is it?
A full plastic cover is included as standard, in the COV / 400 style, measuring 2 W x 3 H x 10-1/8 L inches. If you need the closer body concealed for appearance in a lobby or guest corridor, that is already in the box; there is no separate cover to order.
9) What adjustments can I make on the Cal-Royal 300PBFCOV after it is installed?
Closing speed and latching speed are controlled independently by two separate regulating valves, so you can slow the sweep without losing the push needed to latch. There is also a standard adjustable back-check valve that resists a door being thrown open hard, which protects the door, the frame and the closer itself. Spring size is adjustable across the 1 to 4 range.
10) Can I get the Cal-Royal 300PBFCOV with a hold open feature?
The 300PBFCOV as described carries a regular arm with dual valve control, back-check, and an optional adjustable delayed action, which slows the door rather than holding it. If you need a true hold open, that is an arm or track function: Deltana offers the DCHA1050 hold open arm for its DC10 closer, and LCN offers the 4040SEH-3038 hold open track for the 4000 Series. Match the arm to the closer family it belongs to, since these are not interchangeable with the Cal-Royal body.
11) What finishes does the Cal-Royal 300PBFCOV closer come in?
Three: aluminum, duronodic, and gold. Aluminum and duronodic are the usual picks for matching existing commercial door hardware, gold for finished lobby and hospitality openings.
12) Is the Cal-Royal 300PBFCOV closer suitable for a house or apartment interior door?
It is classed as commercial hardware, sized and tested for commercial traffic in offices, retail, hotels and institutional buildings. It will function on a residential door within the 30 to 185 lb range, but the reason to buy it is Grade 1 commercial duty on a multi-family or MRO opening rather than a single home interior door.
13) For a fire rated opening, is the Dorma 15323 offset bottom arm an alternative to a Cal-Royal 300PBFCOV?
They are different kinds of item. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, standard duty, and it carries no fire rating. The Cal-Royal 300PBFCOV is a complete surface mounted hydraulic closer with dual regulating valves for closing and latching speed, a standard adjustable back-check valve, and factory testing to meet or exceed ANSI A156.4 Grade 1 for commercial use.
