Cal-Royal 500PBF-DURO – Frequently Asked Questions

1) Will the Cal-Royal 500 Series closer work on an ADA interior door, and how heavy a door can it handle?

The Cal-Royal 500 Series is a barrier free closer built for ADA-compliant interior doors, non-sized and fully adjustable through spring sizes 1 to 5, covering doors from 30 to 260 lbs. Because the spring power is adjustable rather than fixed, one closer can be dialed down for a light office door or up for a heavier corridor door, which is what makes it work for accessible openings where opening force has to stay low.

2) Does the Cal-Royal 500 closer fit the existing mounting holes on a door I am replacing a closer on?

It uses a universal mounting hole pattern based on the standard size #4 pattern at 9-1/16 inches, which is the common commercial layout, so on a retrofit where the old closer used a standard #4 prep the holes line up without redrilling. Measure the hole spacing on the existing door or frame first; if it is a proprietary non-standard pattern, you will be drilling new holes regardless of brand.

3) What is the difference between the Cal-Royal 500PBF and N500PBF?

Both are the same closer body; the difference is what ships in the carton. The 500PBF comes packed with the PA bracket only. The N500PBF is the complete install kit: slim plastic cover (500COV), sex bolts (970), and the PA bracket (505). If you are hanging a closer on a hollow-core or mineral-core door where you need to bolt through, or you want the cover included instead of buying it separately, order the N500PBF.

4) Is the Cal-Royal 500 Series closer Grade 1, and is that enough for a school or hospital corridor?

It is factory tested to meet or exceed ANSI/BHMA A156.4 Grade 1, the top commercial durability tier for door closers, and it is specified as a commercial product. Grade 1 is what most institutional specs call for on corridor and public-area doors, so it satisfies the line item where a drawing says A156.4 Grade 1 surface closer.

5) I need the door to stay open on its own. Will the Cal-Royal 500PBF do that?

No. The 500PBF and N500PBF ship with a PA bracket and a regular closing arm, not a hold open arm, so the door returns to closed every time. For a genuine hold open, order a closer specified with one: the Accentra 51 Series comes with a tri-packed hold open arm, and the Orca BHDC1958HO/PA is a hold open closer with parallel bracket for 1-3/4 inch doors.

6) What is a direct Grade 1 surface closer alternative to the Cal-Royal 500 series if I need a non-handed adjustable unit?

The Cal-Royal 500 series is a Grade 1 non-sized closer fully adjustable across sizes 1 through 5. Close equivalents in adjustable Grade 1 surface closers include the Calibre CA9901, a Grade 1 tri-pack arm ADA surface mount closer covering sizes 2 through 5, and the Norton Rixson 8501A, a Grade 1 tri-mount surface closer with an adjustable size 1-6 spring. Both are surface mounted like the 500 and cover the mid-range spring powers a barrier free interior opening needs.

7) I need a closer with more spring power range than sizes 1 to 5 - what should I order instead?

The Cal-Royal 500 series adjusts across sizes 1 through 5 for doors 30 to 260 lbs. Where an opening needs size 6 spring power, the Arrow DCN325 is a Grade 1 surface closer with adjustable spring size 1 through 6, the BEST EHD9000 is an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1-6, and the Imperial USA TC4300 is a heavy duty Grade 1 size 1-6 ADA closer. All three extend the top of the adjustment range past size 5.

8) The Cal-Royal 500 closer is a non-hold-open unit. What comparable closer holds the door open?

The Cal-Royal 500 series ships in the 500PBF configuration with a PA bracket and in the N500PBF configuration with slim plastic cover, sex bolts and PA bracket, neither of which is a hold open arm. For a hold open function, the Accentra 51 series is an industrial closer with a tri-packed hold open arm across sizes 1-6, the Orca BHDC1958HO/PA carries a tri-packed hold open arm with a parallel bracket, and the Stanley A45-501HL is a long hold open arm standard for top jamb mounting.

9) What should I use instead of the Cal-Royal 500 on a heavy exterior or high traffic door?

The Cal-Royal 500 series is engineered for interior doors weighing 30 to 260 lbs. For heavy duty service, the Sargent 1431 Powerglide is a heavy-duty Grade 1 surface closer with adjustable spring power, the Falcon SC71A is a heavy-duty Grade 1 surface-mount closer, the LCN 1460T is a heavy duty surface closer in a powder coat finish, and the BEST HD8000 is a heavy duty Grade 1 surface closer. Each is rated heavy duty rather than to an interior barrier free door weight range.

10) I need delayed action on an accessible opening - does the Cal-Royal 500 offer it, and what does?

The Cal-Royal 500 series controls closing and latching speed through two separate regulating valves and adds an adjustable back-check valve. For a delayed action function instead, the Orca BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket, and the Orca BHDC2011DA/PA is a delayed action closer with a regular arm and parallel bracket; both are listed for 1-3/4 inch doors.

11) The Cal-Royal 500 ships with a parallel arm bracket - what closer do I order for a slide track or slim line arm opening?

The Cal-Royal 500 series comes packed with a PA bracket in both the 500PBF and N500PBF configurations, which is a swing arm setup. For track hardware, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard for pull side mounting, and the Dorma 8916-JT is a Grade 1 surface closer with a jamb track for frame face pull side mounting, adjustable size 1-6.

12) If my spec calls out ANSI A156.4 Grade 1 and Falcon, which Falcon closer meets it and which does not?

The Cal-Royal 500 series is factory tested to meet or exceed ANSI standard A156.4 Grade 1. Among Falcon closers, the SC81A is a Grade 1 medium duty cast aluminum surface closer, the SC61A is Grade 1 light to medium duty, and the SC71A is Grade 1 heavy duty. The Falcon SC91A is a Grade 3 light duty closer, so it will not satisfy a Grade 1 call-out.

13) What closer do I use on an aluminum storefront door where the Cal-Royal 500 is not the right fit?

The Cal-Royal 500 series is built for interior commercial doors 30 to 260 lbs on a universal #4 mounting hole pattern. On an aluminum storefront frame, the Norton Rixson 1600BC series is a heavy duty Grade 1 aluminum storefront closer with tri-style mounting, and the Dorma 8916-JT is a Grade 1 heavy duty closer with jamb track frame face mounting on the pull side, which suits narrow top rails.

14) Do I need to order anything extra to get a finished cover on the Cal-Royal 500 closer?

Depends which pack you buy. The N500PBF already includes the slim plastic cover, part 500COV. With the 500PBF you get the PA bracket only, so add the 500COV cover (2" W x 3" H x 10-5/8" L) separately, or step up to the stainless steel full cover, part 500COV 32D, where the opening is on public display and you want a metal finish rather than plastic.

15) Will a door closer stop a door from slamming into the wall when someone throws it open?

That is what back-check does, and the Cal-Royal 500 Series has a standard adjustable back-check valve. It cushions the swing hydraulically near the end of the opening arc so the door, frame and closer arm are not shocked by a forceful push, common in wind-loaded entries and high-traffic corridors. It is not a substitute for a door stop or overhead stop at a hard limit, but it takes the violence out of the open swing.

16) Can I adjust closing speed and latching speed separately on the Cal-Royal 500 closer?

Yes, they are on two separate regulating valves. Dual valve control means you can slow the main sweep for accessibility while keeping a faster last few degrees so the latch actually throws into the strike. That is the usual fix when a door drifts to the frame and stops short without latching.

17) Should I use an adjustable size 1-5 closer or a fixed-size one for a building with mixed door weights?

For a mixed fleet, non-sized wins. The Cal-Royal 500 Series covers spring sizes 1 through 5 in one unit, so a property manager can stock one part number and dial each opening in on site rather than carrying separate sizes per door. That also means a closer pulled off one door can be reused on another. Fixed-size closers only make sense when every opening is identical and already specified.

18) What is a good alternative to the Cal-Royal 500 closer if I need a heavier duty unit for an exterior or high-abuse door?

The 500 Series is a barrier free closer for interior doors 30 to 260 lbs. If the opening is exterior or takes real abuse, move to a heavy duty Grade 1 unit: the BEST HD8000 Series or EHD9000 Series, the Falcon SC71A, the Sargent 1431 Powerglide, or the Dormakaba 8600 Series 8616 with flat arm are all heavy duty Grade 1 surface closers. Same mounting concept, more spring and body capacity.

19) What is the closest equivalent to the Cal-Royal 500PBF from another brand?

For an adjustable ADA Grade 1 surface closer in the same class, the Calibre CA9900 Series CA9901 is a tri-pack arm ADA closer covering sizes 2 to 5, and the Calibre CA4000 Series CA4001 is an adjustable spring tension ADA hydraulic closer. The LCN 1250 Series is a light duty ADA-compliant closer with sizes 1 to 5, the same spring range as the Cal-Royal 500. Where a spec calls for a named architectural brand, the Norton Rixson 1601P or the Sargent 1131 are Grade 1 medium duty adjustable surface closers.

20) Do I need sex bolts to install a door closer, and are they included with the Cal-Royal 500?

Sex bolts through-bolt the closer so the load is carried by the door skin on both faces rather than screws biting into a hollow or composite core, and many institutional specs require them on wood doors. The N500PBF includes them (part 970). The 500PBF does not, so if you are mounting on a wood or hollow-core door and need through-bolting, take the N500PBF pack.

21) Is there a lighter duty closer than the Cal-Royal 500 for a low traffic interior door?

The Cal-Royal 500 series is a Grade 1 commercial closer covering doors 30 to 260 lbs. Where a lighter unit suits the opening, the BEST SL6000 is a light duty Grade 1 surface closer with adjustable spring sizes, the Norton Rixson 160 series is a light duty Grade 1 light commercial closer with an adjustable spring, the Arrow DC314 is a light duty Grade 1 surface closer, and the LCN 1250 is a light duty ADA compliant closer in sizes 1-5 with all-weather fluid.

22) Which closers are tri-mount like the Cal-Royal 500 so one part number covers regular, parallel and top jamb openings?

The Cal-Royal 500 series uses a universal mounting hole pattern built on standard size #4 mounting holes at 9 1/16 inches, for new construction and retrofit. Other closers that carry a single tri-mount part number include the Dexter DCH4000, a Grade 1 surface closer for regular, parallel or top jamb mounting, the Dexter DCM1000 in the same tri-mount arrangement, and the Norton Rixson 1601P, a Grade 1 tri-mount closer with 180 degree swing.

23) Will an Arrow DCN500DP parallel drop plate work with a Cal-Royal 500 closer?

No. The Arrow DCN500DP is a parallel drop plate for the Arrow DCN500 closer, not a closer itself, and it is built to that body. The Cal-Royal 500 series uses its own universal mounting hole pattern on standard size #4 mounting holes at 9 1/16 inches and ships with the Cal-Royal 505 PA bracket in the N500PBF configuration. The similar 500 in the two part numbers is coincidence, not shared hardware.

24) I am standardizing an office building on one closer - what Grade 1 medium duty options match a Cal-Royal 500 for a fleet buy?

The Cal-Royal 500 series is a commercial Grade 1 closer for interior doors 30 to 260 lbs, sized in the field from 1 to 5, which is what makes one part number cover a mixed set of openings. Grade 1 medium duty peers that behave the same way across a building are the Sargent 1131 and Sargent 1331, both Grade 1 medium duty adjustable surface closers, the Norton Rixson 8501A with adjustable size 1-6 spring, and the BEST HD7000 with adjustable spring power and backcheck control.

25) Which closers besides the Cal-Royal 500 offer backcheck control for a door that gets thrown open into a wall?

The Cal-Royal 500 series includes a standard adjustable back-check valve that protects the door, frame and closer from forceful opening. Peers that also carry backcheck include the BEST HD7000, a Grade 1 medium duty surface closer with adjustable spring power and backcheck control, and the Norton Rixson 1600BC series aluminum storefront closer, a heavy duty Grade 1 unit with tri-style mounting.

26) Is a Corbin Russwin DC3200 a workable replacement for a Cal-Royal 500 on a 1-3/4 inch door?

The Corbin Russwin DC3200 is a Grade 1 surface mounted closer with a regular arm, listed for 1-3/4 inch door thickness. The Cal-Royal 500 series is also Grade 1 and surface mounted, but ships with a PA bracket for parallel arm mounting in both the 500PBF and N500PBF configurations. Swapping to the DC3200 means changing to regular arm mounting on the pull side, so confirm which face of the door the existing closer sits on before ordering. The Corbin Russwin DC6200 and DC8200 are also Grade 1 for 1-3/4 inch doors but use a double lever regular arm on the pull side.

27) What finishes does the Cal-Royal 500 Series barrier free closer come in?

Four: plated aluminum, black, duronodic, and gold. All four are offered in both the 500PBF and N500PBF packs, so the carton contents do not limit your finish. Aluminum and duronodic are the usual matches for storefront and dark bronze frames; black suits painted hollow metal.

28) The PA bracket comes with the Cal-Royal 500 closer. When do I actually need it?

You need the parallel arm bracket when the closer mounts on the push side of the door with the arm running parallel to the face, which is the usual choice on corridor and exterior-facing openings where you want the closer body tucked out of the swing path and less exposed to abuse. Both the 500PBF and N500PBF include the bracket (part 505 in the N kit), so parallel arm mounting is covered in the box either way.

29) Are the Stanley 327 and 341 pivots an alternative to a Cal-Royal 500 door closer?

No. The Stanley 327 is a heavy wardrobe pivot for 1-3/8 inch or 1-3/4 inch doors up to 150 lbs and the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 inch to 1-3/8 inch. Those carry and swing a door; they do not close it. The Cal-Royal 500 series is a hydraulic surface mounted closer with dual regulating valves for closing and latching speed and an adjustable back-check valve. A pivot opening still needs a closer.
