Cal-Royal 750-ALUM-BC – Frequently Asked Questions

1) What size door does the Cal-Royal 750 door closer cover, and how do I pick the right size?
The 750 is the Size 5 closer in Cal-Royal's 700 Series. It's a sized (non-adjustable) closer, so you pick the model to match the door rather than dialing spring power down on site. The rest of the family is the 720 (Size 2), 730 (Size 3), and 740 (Size 4). Size 5 is the heaviest of the four, so it's the one for wide or heavy exterior openings; on a light interior office door a Size 5 will be harder to pull than occupants expect, and you'd step down to a 730 or 740. If you'd rather have one closer that covers a range of openings, an adjustable spring closer such as the BEST EHD9000 Series or the Norton Rixson 8501A covers sizes 1 through 6 in a single unit.
2) Is the Cal-Royal 750 closer handed, or does one part number work on left and right hand doors?
Non-handed. One 750 works on either hand, and Cal-Royal builds it for all standard commercial and residential installations without adaptors. For a property manager stocking spares that means a single part number covers every door of that size in the building, left or right. Choose the arm to suit the mounting: regular arm, parallel arm, or hold-open.
3) Will the Cal-Royal 750 hold up on a high-traffic commercial entrance?
It meets and exceeds ANSI Standard A156.4 Grade 1, which is the top durability tier for door closers and the level typically specified for schools, hospitals, and commercial entrances. The mechanism is rack and pinion inside a high tensile precision cast aluminum housing, and the hydraulic fluid is formulated for high lubricity across the closer's service life. It is catalogued for commercial use.
4) Can I mount a Cal-Royal 750 closer on the push side of the door?
Yes. The 750 ships with your choice of regular, parallel, or hold-open arm. Regular arm mounts on the pull side, parallel arm mounts on the push side with the arm tucked flat against the door face, which is the usual choice where the closer would otherwise stick out into a corridor or be a target for vandalism. The reinforced adjustable tube arm is built to suit a range of door and frame configurations.
5) My spec calls for a slide track or concealed-style arm. Can I use the Cal-Royal 750?
The Cal-Royal 750 uses a reinforced adjustable tube arm and is offered with Regular, Parallel, or Hold-Open arm choices, so it is a projecting arm closer. If the drawing calls for a track arm, the Corbin Russwin DC5230 Series is a Grade 1 surface closer with a slide track arm standard, pull side mounted, for 1-3/4 inch doors, and the Dorma 8916-JT is a Grade 1 heavy duty surface closer with a jamb track, frame face mounted on the pull side and adjustable size 1-6. For a low profile projecting arm, the Dormakaba 8616 AF86P FC SNB1 689 is a Grade 1 heavy duty closer with a flat non-hold open arm supplied tri-pack.
6) What is a Grade 1 surface closer equivalent to the Cal-Royal 750 if I need one spring size that covers a range of doors instead of a fixed size?
The Cal-Royal 750 is a fixed Size 5 closer from the 700 Series, so its spring power is set by the model you order. If you would rather stock one closer and dial the power in on site, the Arrow DCN325 is a Grade 1 surface closer with adjustable spring size 1 through 6, and the Norton Rixson 8501A is a Grade 1 tri-mount surface closer with an adjustable size 1-6 spring. The BEST EHD9000 Series is an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1-6 as well. All three cover Size 5 within their adjustment range, so one unit can be set to match a 750 on a wide or heavy door and set lower on a lighter one.
7) I have a lighter interior door that does not need Size 5 spring power. What surface closer should I use instead of the Cal-Royal 750?
The Cal-Royal 750 is the Size 5 model in the 700 Series and is built for commercial openings that need that spring power. For a lighter interior opening, the BEST SL6000 Series is a light duty Grade 1 surface closer with adjustable spring sizes, the Arrow DC314 is a light duty Grade 1 surface closer in the DC300 Series, and the Norton Rixson 160 Series is a light duty Grade 1 light commercial surface closer with an adjustable spring. The Falcon SC91A is a light duty cast aluminum surface closer certified to Grade 3 rather than Grade 1, so confirm what grade your spec calls for before using it.
8) The opening gets constant abuse and I want something heavier than a Cal-Royal 750. What are the heavy duty Grade 1 options?
The Cal-Royal 750 is a Grade 1 Size 5 closer with a high tensile precision cast aluminum body. For a heavier duty rating, the BEST HD8000 Series and BEST EHD9000 Series are both heavy duty Grade 1 surface closers, the Falcon SC71A Series is a heavy duty Grade 1 surface closer, and the Sargent 1431 Powerglide is a heavy duty Grade 1 surface closer with adjustable spring power. The Sargent 281 Powerglide is heavy duty Grade 1 with a cast iron body rather than aluminum, which matters if you want the heavier housing material on a high abuse door.
9) I need delayed action so a wheelchair or a cart can clear the door. Is the Cal-Royal 750 the right closer for that?
The Cal-Royal 750 controls closing and latching speed through two separate regulating valves and offers optional backcheck, which cushions the swing on a forceful opening. Backcheck and delayed action are not the same function. If the opening needs the door to pause before it starts to close, the Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket for 1-3/4 inch doors.
10) I need an ADA compliant closer with adjustable spring tension rather than a fixed Size 5. What are my options?
The Cal-Royal 750 is the fixed Size 5 model of the 700 Series, with the line also offered in Size 2, Size 3 and Size 4 for matched application sizing. If the opening has to be adjusted down to meet an ADA opening force, the Calibre CA9901 is a Grade 1 tri-pack arm size 2-5 ADA surface mount closer, the Calibre CA4001 is a Grade 1 adjustable spring tension ADA hydraulic closer, and the Imperial USA TC4300 Series is a heavy duty size 1-6 ADA closer. The LCN 1250 Series is a light duty closer in sizes 1-5 with all-weather fluid and is described as ADA compliant.
11) I am replacing a Cal-Royal 750 on one door in a building where the rest run a different brand. What lines give me a Size 5 capable match across a whole property?
The Cal-Royal 750 covers Size 5 as a fixed size. To match it while standardizing the rest of a property on a single adjustable line, the Accentra 2701 Series is an architectural closer with adjustable spring sizes 1-6 and tri-pack mounting, the Accentra 51 Series covers size 1-6 with a hold open arm, and the Norton Rixson 8501A is a Grade 1 tri-mount closer adjustable size 1-6. Each of those spans Size 5, so the same part number can be set high on an exterior door and low on a light interior one. The Accentra 1101BF covers sizes 1-4 only, so it will not reach Size 5.
12) What does backcheck do on a door closer, and do I need it?
Backcheck cushions the door near the end of its opening swing so it can't be flung into the adjacent wall or slam the arm against its stop. On the Cal-Royal 750 it's an optional function that helps reduce hardware damage from forceful opening. You want it on exterior doors that catch wind, on doors with no wall stop, and anywhere occupants shove doors open hard. On a protected interior opening it matters much less.
13) How do I adjust the closing speed and the latching speed separately on the Cal-Royal 750?
There are two separate regulating valves on the 750, one for closing speed and one for latching speed. That's what dual valve means here. Closing speed governs the door's travel through most of the swing; latching speed governs the last few inches where it has to overcome the latch and any weatherstrip. So you can slow the general sweep for occupants while keeping enough snap at the end to seat the latch, without one adjustment fighting the other.
14) Can the Cal-Royal 750 replace an existing surface closer without drilling new holes?
The 750 uses a universal hole pattern and Cal-Royal builds it for both new construction and retrofit work, so in many cases it lands on existing prep. What decides it is the pattern already in your door or frame: pull the old closer, check the hole spacing against the 750's template before you commit, and be ready to use a filler or shim plate if the old unit had a proprietary layout.
15) I have a mix of door sizes in one building. Should I buy sized closers or adjustable ones?
Sized closers like the Cal-Royal 750 are set at the factory for one door size, so each opening gets the matched model out of the 700 Series (720, 730, 740, 750). That's clean when the door schedule is known and you want consistent feel across identical openings. If your doors vary, or you're stocking spares for a portfolio and don't want four part numbers on the shelf, an adjustable-spring closer covers a band in one unit: the Norton Rixson 8501A and the BEST EHD9000 cover sizes 1 through 6, the Calibre CA9901 covers 2 through 5, and the LCN 1250 covers 1 through 5. Trade-off is that adjustable units have to be set correctly at install, and a wrongly set one is the usual cause of a door that won't latch.
16) Is the Cal-Royal 750 ADA compliant for opening force?
The 750 is a Size 5 closer, which is the heavy end of the 700 Series. ADA interior opening force limits are met by reducing spring power, so a Size 5 is generally the wrong choice where an opening-force limit applies. If ADA compliance is the requirement, ZenSupply carries closers specified for it directly, including the Calibre CA9901 (ADA, size 2-5), the Calibre CA4001 adjustable spring tension ADA closer, the Imperial USA TC4300 (size 1-6 ADA), and the LCN 1250, which is listed as ADA compliant.
17) I need a closer that holds the door open. Does the Cal-Royal 750 do that, and what else will?
The Cal-Royal 750 is offered with a choice of Regular, Parallel, or Hold-Open arms, so the hold open function is an arm selection made at order time. If you want a peer with the hold open arm called out, the Accentra 51 Series is supplied with a tri-packed hold open arm in sizes 1 through 6, and the Orca Hardware BHDC1958HO/PA is a hold open closer with a tri-packed hold open arm and a parallel bracket for 1-3/4 inch doors. The Stanley Security A45-501HL uses a long hold open arm in a top jamb application.
18) What is the difference between the Cal-Royal 750 and a tri-pack closer like the Dexter DCH4000 or Arrow DCN314?
The Cal-Royal 750 is a non-handed universal closer with a universal hole pattern, and the arm style is chosen at order time from Regular, Parallel, or Hold-Open. A tri-pack ships the hardware for more than one mounting in the same carton: the Dexter DCH4000 Series is a Grade 1 surface closer packed for tri mount, meaning regular, parallel, or top jamb mounting, and the Arrow DCN314 is a Grade 1 surface closer supplied regular and parallel arm tri-pack with adjustable spring size 1 through 4 and no cover. The Dexter DCH1000 Series is a Grade 1 tri mount closer that includes a full cover. For a stocking distributor, a tri-pack means one part number covers whichever mounting the opening turns out to need.
19) Is the Cal-Royal 750 the right closer for an aluminum storefront door?
The Cal-Royal 750 is a commercial closer built for standard commercial and residential installations without adaptors. For a narrow stile aluminum storefront, the Norton Rixson 1600 Series aluminum storefront door closer is a heavy duty Grade 1 unit with tri-style mounting made for that opening. If you go with a parallel mount on a DCN500 body, the Arrow DCN500DP parallel drop plate is the bracket that carries it.
20) My facility standard is ANSI A156.4 Grade 1. Which closers besides the Cal-Royal 750 hold that grade?
The Cal-Royal 750 meets and exceeds ANSI Standard A156.4 Grade 1. Other Grade 1 surface closers include the Corbin Russwin DC3200, DC6200 and DC8200, all Grade 1 surface closers for 1-3/4 inch doors, the Sargent 1131 and 1331 medium duty Grade 1 closers, the Falcon SC81A medium duty Grade 1 and SC61A light to medium duty Grade 1, the Norton Rixson 1601P medium duty Grade 1 tri-mount with 180 degree swing, and the Calibre CA9901, CA4001, CA5501 and CA8001P, all Grade 1. That gives a facility several Grade 1 lines to standardize on across different door weights.
21) What finishes does the Cal-Royal 750 door closer come in?
Two: aluminum and duronodic. Aluminum matches the clear anodized storefront and aluminum-framed doors most commercial entries use; duronodic is the dark bronze tone, for bronze-anodized frames and darker hardware suites. Both are the same closer underneath, so a mixed building can run one model across every opening and just order the finish that suits each frame.
22) Do I need a cover for the Cal-Royal 750, or is one included?
A slim plastic cover is offered as an option on the 750, so specify it if you want the body concealed. Plenty of commercial jobs run the closer bare, and some specs call for it, but on a lobby or a public corridor the cover is usually what the architect expects to see. Worth calling out on the order, since it isn't automatic.
23) What is the difference between a cast aluminum door closer body and a cast iron one?
The Cal-Royal 750 uses a high tensile precision cast aluminum housing. Aluminum bodies are lighter and don't corrode, which is why they dominate storefront and general commercial work. Cast iron bodies are the traditional heavy-duty alternative, used where abuse resistance outweighs weight; among the closers ZenSupply carries, the LCN 1261 and the Sargent 281 Powerglide are cast iron. If the opening is a normal commercial entry or interior door, aluminum is the standard choice and the 750 is Grade 1 either way.
24) The Cal-Royal 750 comes in Aluminum and Duronodic. What if I need a different finish on a matched set of doors?
The Cal-Royal 750 is stocked in Aluminum and Duronodic finishes. If the building standard is something else, the DORMA 7303 Series is a medium duty Grade 1 surface closer supplied in a painted finish, and the LCN 1460T is a heavy duty Grade 1 commercial closer in a powder coat finish. Both are surface mounted closers, so the mounting approach on the door is the same even though the appearance differs.
