Cal-Royal DPF-4-DURO – Frequently Asked Questions

1) Does the Cal-Royal DFG888 hold the door open, and at what angle?
Hold-open is at 90 degrees. The door stops and stays there when you swing it to square, which is what you want on a retail or office entry during delivery hours. If you do not want that behavior, order the DFG888-NHO, the non hold-open version of the same closer.
2) Can a glass door on a Cal-Royal DFG888 swing both directions?
Yes, it is a double action closer, opening up to 150 degrees left and right. That makes it suitable for a two-way traffic entry where people push through from either side. Handing is not something you specify on this one, since it works both ways out of the box.
3) How much adjustment does the Cal-Royal DFG888 base seat give if the floor pocket is not perfectly placed?
The base seat moves plus or minus 0.12 inch (3mm) forward and back, plus or minus 0.12 inch (3mm) left and right, and gives 4 degrees of alignment adjustment. That is your margin for a cement case set slightly off, and it is also why the DFG888 does not require a preset on the floor before the pour. On glass, where you cannot trim the door to hide an error, that adjustment is what saves the install.
4) What is the difference between the Cal-Royal DFG888 floor closer and the Dorma BTS75V?
The Cal-Royal DFG888 is a concealed glass floor closer built for frameless glass doors, with a 150 degree opening angle for both left and right hand double action operation, hold-open at 90 degrees, and a rated door weight of up to 220 lbs. The Dormakaba BTS75V is supplied as a floor closer body only with cement case, less spindle, and is a Grade 1 unit with a non hold-open function. So the two differ on hold-open: the DFG888 holds the door at 90 degrees, while the BTS75V is NHO and returns the door to closed every cycle. If the DFG888 hold-open is not wanted, Cal-Royal builds the DFG888-NHO for exactly that case.
5) My spec calls for a Grade 1 floor closer - which floor closers carry a Grade 1 rating?
Among the commercial floor closers Cal-Royal, Dormakaba and Norton Rixson build, the Dormakaba BTS75V floor closer body is Grade 1, the Norton Rixson H28 Series concealed floor closer for offset-hung doors is Grade 1 heavy duty, and the Norton Rixson 25 Series floor closer cement case is Grade 1 heavy duty galvanized steel construction. If the submittal has a Grade 1 line item on it, those are the parts that answer it directly.
6) Is the Norton Rixson 25 Series cement case a substitute for the Cal-Royal DFG888?
No - they are different parts in the assembly. The Norton Rixson 25 Series item is a floor closer cement case in heavy-duty galvanized steel, the box that gets set in the floor, and it is Grade 1 heavy duty. The Cal-Royal DFG888 is the closer itself, a concealed glass floor closer measuring 7.32 in. long by 2.68 in. wide by 1.42 in. thick with an adjustable base seat that trims plus or minus 0.12 in. front to back and side to side plus 4 degrees of alignment. Ordering the 25 Series cement case will not give you a working closer, and it will not accept the DFG888 body.
7) I need a floor closer that swings the door a full 180 degrees - does the Cal-Royal DFG888 do that?
The Cal-Royal DFG888 opens to 150 degrees, left and right, in double action configurations. If the opening truly needs 180 degrees, the Norton Rixson 20 Series is a 3/4 in. offset hung floor closer with 180 degree door swing capability, built as a standard duty unit. Note that the 20 Series is an offset hung design, so the door prep is different from the frameless glass arrangement the DFG888 uses.
8) The building's glass doors are already on Cal-Royal DFG888 closers and one is failing - can I drop in a Dorma BTS80?
Treat that as a different part, not a drop-in. The Dormakaba BTS80 is a concealed floor closer body only, heavy duty, in the BTS80 Series. The Cal-Royal DFG888 is a concealed glass floor closer with its own adjustable base seat that trims plus or minus 0.12 in. backward and forward, plus or minus 0.12 in. left and right, and 4 degrees of alignment, and it needs no floor preset. To match the existing doors, stay on the DFG888 - it comes in Duronodic and US32D satin stainless steel - and pick DFG888-NHO only if that door is meant to close every time rather than hold at 90 degrees.
9) Should I use a hold-open floor closer or a non hold-open one on a glass entry door?
Hold-open, the standard DFG888, parks the leaf at 90 degrees, useful on entries where staff need the door propped for carts or deliveries. Non hold-open, the DFG888-NHO, always returns the door to closed, which is what you want on a door that has to stay latched for security or on any opening where a propped door defeats the purpose. Both are the same body and the same 220 lbs capacity, so the choice is purely about whether the door should be able to stay open on its own.
10) I need a non hold-open floor closer for a fire-rated or secure opening. What are my options besides the Cal-Royal DFG888?
On the Cal-Royal side, order the DFG888-NHO, the non hold-open build of the same closer. From another brand, the Dormakaba BTS75V is a Grade 1 floor closer with a non hold-open function, sold as a body only with cement case and less spindle, so you would need to specify the spindle separately. Which one fits depends on the door: the DFG888 is a frameless glass closer with a 29.5 to 39.4 inch width range, while the BTS75V is a general concealed floor closer body.
11) Does the Cal-Royal DFG888 floor closer come with the cement case, or do I order that separately?
The DFG888 is described as a standard concealed glass floor closer with an adjustable base seat and no floor preset required, so the adjustment for a slightly off pocket is built into the closer itself. If you are pricing a job where the case is a separate line, note that some floor closers are sold that way: the Norton Rixson 25 Series cement case is a stand-alone galvanized steel case item, and the Dormakaba BTS80 is sold as a body only. Confirm the case arrangement on your order before the slab goes in.
12) We are standardizing floor closers across a building on heavy duty units - what are the heavy duty options?
The Dormakaba BTS80 concealed floor closer body is heavy duty, the Norton Rixson H28 Series concealed floor closer for offset-hung doors is heavy duty and Grade 1, the Norton Rixson 127 Series 3/4 in. offset closer is heavy duty, and the Norton Rixson 25 Series cement case is heavy duty. The Norton Rixson 20 Series is standard duty, so it sits outside a heavy duty standardization. Note the openings differ: the H28 and 127 are offset-hung designs, while the Cal-Royal DFG888 handles the frameless glass doors up to 220 lbs. in the same building.
13) Which floor closer should I use on a fire-rated opening?
Not the Dormakaba BTS80 - it is a heavy duty concealed floor closer body carrying a fire rating of No. The Cal-Royal DFG888 is a concealed glass floor closer with hold-open at 90 degrees, and hold-open behavior is generally not what a fire-rated opening wants in the first place; Cal-Royal builds the DFG888-NHO as the non hold-open version, and the Dormakaba BTS75V is likewise a non hold-open unit. Confirm the fire listing with the authority having jurisdiction for the specific opening before you commit.
14) What finishes does the Cal-Royal DFG888 come in?
Two: Duronodic (dark bronze anodized) and US32D satin stainless steel. On a floor closer the only visible part is the cover plate and the top patch hardware, so pick the one that matches the rest of the glass door patch fittings and rails rather than the frame.
