Cal-Royal 420-P-ALUM – Frequently Asked Questions

1) Is the Cal-Royal 400 door closer handed, or does one unit work on both left and right hand doors?
One unit works either hand. The 400 Series is a non-handed universal design, so the same closer installs on a left or right hand door with no adaptor and nothing to order per opening. For a property manager stocking spares that means one part number per size and finish covers every door of that weight in the building, rather than a left and a right on the shelf.
2) Does the Cal-Royal 400 closer come with the parallel arm mounting bracket, or do I have to buy it separately?
The bracket is in the box. Each 400 Series closer ships with a parallel bracket, machine screws, and self-tapping wood screws, plus the reinforced adjustable tube arm. All nine orderable combinations are the parallel arm configuration. What is not included is a drop plate or a soffit/shoe support bracket, so if the opening has a narrow top rail or a stop that will not take the parallel bracket, plan on that separately.
3) Is the Cal-Royal 400 Series ANSI Grade 1 or Grade 2?
Grade 2. The 400 Series meets and exceeds ANSI Standard A156.4 at Grade 2, which suits general commercial and multi-tenant residential traffic. If a spec or a facility standard calls for Grade 1 on the opening, the 400 will not satisfy it and you want a Grade 1 surface closer instead, such as the Sargent 1431 Powerglide or the BEST HD8000 Series, both heavy duty Grade 1 units.
4) The Cal-Royal 400 comes in fixed sizes 2, 3, and 4 - what closer gives one part number that covers a range of door sizes instead?
The Cal-Royal 400 Series is sized: 420-P is Size 2 for 55 to 100 lb doors, 430-P and SM430-P are Size 3 for 88 to 143 lb doors, and 440-P is Size 4 for 120 to 187 lb doors, so the size is chosen at order time. If you would rather stock one closer and dial the spring on site, the Accentra 1101BF carries adjustable spring sizes 1-4, the Arrow DCN314 is adjustable size 1 through 4, and the Arrow DCN325 and Norton Rixson 8501A both cover adjustable sizes 1 through 6. The Calibre CA9901 covers sizes 2-5 with a tri-pack arm. This matters for property managers and MRO buyers standardizing one SKU across a mixed door fleet.
5) I need the door to stay open on its own - does the Cal-Royal 400 do that, or do I need a different closer?
The Cal-Royal 400 Series is a hydraulic closer with a reinforced adjustable tube arm and dual valves regulating closing and latching speed; hold open is not part of that arm arrangement. For an opening that has to stand open, the Accentra 51 Series is supplied with a tri-packed hold open arm across sizes 1-6, the Orca BHDC1958HO/PA is a hold open closer with a parallel bracket, and the Stanley Security A45-501HL is a long hold open arm standard, top jamb closer. If the requirement is delayed closing rather than hold open, the Orca BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket.
6) The Cal-Royal 440-P Size 4 is not enough for a heavy exterior door - what closer handles more?
The Cal-Royal 400 Series tops out at 440-P Size 4, rated for door weights of 120 to 187 lbs. Above that, heavy duty closers carry the load: the Sargent 1431 Powerglide and Sargent 281 Powerglide are heavy duty Grade 1 surface closers, the 281 with cast iron construction, and the LCN 1460T is a heavy duty Grade 1 commercial closer in a powder coat finish. The Falcon SC71A and Design Hardware 416 Series are also heavy duty surface closers, and the Dormakaba 8616 is a Grade 1 heavy duty closer with a flat non-hold open arm supplied tri-pack.
7) Which closer should I use instead of the Cal-Royal 400 on an aluminum storefront door?
The Cal-Royal 400 Series uses a rack and pinion mechanism in a cast aluminum body with a reinforced adjustable tube arm and a parallel bracket. For a narrow-stile aluminum storefront, the Norton Rixson 1600 Series aluminum storefront closer is built for that opening with tri-style mounting, Grade 1 and heavy duty. Where the frame face is the only available mounting surface, the Dorma 8916-JT is a Grade 1 jamb track closer for frame face mounting on the pull side, adjustable size 1-6. Slide track is also available from Corbin Russwin as the DC5230, a Grade 1 surface closer with a slide track arm standard and pull side mounting.
8) Does the Cal-Royal 400 Series meet ADA, or should I look at a closer that states it?
The Cal-Royal 400 Series meets and exceeds ANSI Standard A156.4 at Grade 2, with dual regulating valves that let the installer tune closing and latching speed independently. Closers that state ADA in their own description include the Calibre CA9901 tri-pack arm size 2-5 ADA surface mount closer, the Calibre CA4001 with adjustable spring tension, the Calibre CA8001P parallel arm size 1, the Imperial USA TC4300 Series Grade 1 heavy duty size 1-6 ADA closer, and the LCN 1250 Series in sizes 1-5. For a facility writing ADA opening force into the spec, those are the ones that carry the claim on the part.
9) Can you adjust the closing and latching speed separately on a Cal-Royal 400 closer?
Yes, two independent valves. One regulates the general closing sweep and the second controls latching speed over the last few inches of travel, so you can slow a door that slams into the frame without making the whole swing sluggish, or speed up the latch on a door that stalls before the latchbolt engages. That is the adjustment you make on a call-back when a tenant complains the door bangs.
10) Does the Cal-Royal 400 door closer have back check to stop the door hitting the wall?
Back check is an option on the 400 Series, not standard on every unit, so it has to be called out when ordering along with the optional full cover. Back check matters on an exterior opening where wind can throw the door past the arm, and on any door where there is a wall or a fixture behind it. If back check is a hard requirement on the spec, the Norton Rixson 1600BC Series and the BEST HD7000 Series are surface closers built around backcheck control.
11) Cal-Royal 400 versus an adjustable spring size door closer, which should I buy?
It comes down to whether you know the door weight. A sized closer like the 400 Series is set at the factory for its weight band, so you specify Size 2, 3 or 4 up front and the unit arrives matched to the door. An adjustable spring closer covers a span of sizes in one part number and gets dialed in on site, which is what you want when you are ordering ahead for openings you have not measured or standardizing one SKU across a mixed building. The Arrow DCN314 covers spring sizes 1 to 4 and the Norton Rixson 8501A covers 1 to 6 if that is the route you need. Buy the 400 when the openings are known and consistent.
12) Can I use the Cal-Royal 400 door closer on apartment corridor and unit entry doors?
Yes, it is built for exactly that mix. The 400 Series is a commercial closer rated Grade 2 and is used on multi-tenant residential, office, school, healthcare, retail, industrial and municipal openings. Size the unit per door: a typical hollow metal unit entry usually lands in the Size 2 or 3 band (55 to 143 lbs), while a heavier corridor or stairwell leaf runs into Size 4 territory at 120 to 187 lbs.
13) Is the Cal-Royal 400 a hold open closer?
No. The 400 Series is a standard closing unit with an adjustable tube arm, so the door returns closed every time. If the opening needs to stand open, that is a different arm function and a different order: the Accentra 51 Series and the Orca BHDC1958HO both use a hold open arm. Do not put a hold open on a fire rated opening unless it is a listed hold open release device.
14) I need a closer with delayed action for an accessible door. Does the Cal-Royal 400 do that?
No, the 400 Series regulates closing speed and latching speed only, with no separate delayed action valve. For an opening where someone needs extra time to clear the door, the Orca Hardware BHDC1958DA and BHDC2011DA are delayed action closers built for 1-3/4 inch doors.
15) The Cal-Royal 400 has a cast aluminum body - which comparable closers use cast iron instead?
The Cal-Royal 400 Series houses its rack and pinion mechanism in a high tensile precision cast aluminum body. Among comparable surface closers, the LCN 1261 uses cast iron construction with adjustable spring sizes 1-5, and the Sargent 281 Powerglide is a cast iron surface closer with heavy-duty construction. Cast aluminum peers include the Falcon SC81A and SC61A, and the Sargent 1331, which uses a universal aluminum body. Cast iron and cast aluminum are different housing materials, which matters to specifiers writing a body material into the drawing.
16) Is the Arrow DCN500DP drop plate a substitute for the Cal-Royal 400 closer?
No. The Cal-Royal 400 Series is the complete hydraulic closer itself, supplied with a parallel bracket, machine screws, and self-tapping wood screws. The Arrow DCN500DP is a parallel drop plate for the DCN500 - a mounting plate that drops a closer down onto the door face, not a closer, and it is specific to the Arrow DCN500. Ordering it in place of a closer leaves you with no closer body, arm, or hydraulics.
17) I am replacing a closer on a 1-3/4 inch commercial door - which comparables state that door thickness?
The Cal-Royal 400 Series is non-handed and installs on most standard commercial and residential doors without adaptors, in sizes matched to door weight from 55 lbs up to 187 lbs. Comparable closers that state a 1-3/4 inch door thickness include the Corbin Russwin DC3200 with a regular arm, the DC6200 and DC8200 Series with a double lever regular arm on the pull side, and the DC5230 with a slide track arm - all Grade 1 surface closers. The Orca BHDC1958 closers, in regular arm, hold open, and delayed action versions, are also specified for 1-3/4 inch doors.
18) What differentiates the Cal-Royal 430-P from the SM430-P?
Both the 430-P and the SM430-P are Size 3 configurations of the Cal-Royal 400 Series, covering doors of 88 to 143 lbs with the same rack and pinion mechanism, dual speed valves, and non-handed body. If you are cross-shopping other makers at that same duty point, the Design Hardware 316 Series is rated medium to heavy duty with a tri-packed non-hold open arm, and the BEST HD7000 Series is a medium duty Grade 1 closer with adjustable spring power and backcheck control - the same backcheck feature the 400 Series offers as an option.
19) Does the Cal-Royal 400 door closer come with a cover?
The full cover is an option on the 400 Series, so the plain body is what you get unless the cover is specified. That is a decision worth making before the order goes in, because a bare closer on a lobby or tenant-facing door looks unfinished next to a covered unit. On back of house, mechanical and stair doors most buyers skip it.
20) Are the Stanley 327 and 341 wardrobe pivots alternatives to the Cal-Royal 400 door closer?
No. The Cal-Royal 400 Series is a surface mounted hydraulic door closer that controls closing and latching speed through two regulating valves. The Stanley Security 327 is a heavy wardrobe pivot for doors 1-3/8 inch or 1-3/4 inch 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. Pivots hang and swing the door; they do not close it. If you need the door to self-close, stay with a closer.
21) The Cal-Royal 400 offers a full cover as an option - which closers come with the cover already?
On the Cal-Royal 400 Series, a full cover and back-check are configurable options. If you want the cover as part of the standard build, the Design Hardware 316 Series is a heavy duty closer supplied with cover, and the Dexter DCH1000 Series is a Grade 1 tri mount surface closer with a full cover. Going the other way, the Arrow DCN314 and DCN325 are supplied less cover, which suits back-of-house and service doors where the metal body is left exposed.
22) The Cal-Royal 400 is offered in Aluminum, Duronodic, and Gold - what if I need a painted closer to match existing hardware?
The Cal-Royal 400 Series is finished in Aluminum, Duronodic, or Gold across all three sizes. Where the job calls for a painted body instead, the Dormakaba 7303 Series is a surface-mounted standard duty Grade 1 closer in a painted finish and the Dormakaba 7414 in size 1-4 is also offered painted; both are medium duty. The LCN 1460T is supplied in a powder coat finish. Property managers matching a run of doors usually pick one of these finish families and hold it across the building.
