Cal-Royal DFG888-US32D – Frequently Asked Questions

1) What door width and weight can the Cal-Royal DFG888 floor closer handle?
The DFG888 concealed floor closer is sized for glass doors of 29.5 to 39.4 inches wide (750-1000mm) weighing up to 220 lbs (100kg). Those two limits work together: a door at the top of the width range and near 220 lbs is at the edge of what this closer controls. Wider or heavier entrance leaves need a heavier-duty body such as the Norton Rixson H28 Series concealed floor closer.
2) How much floor pocket do I need to cut for the Cal-Royal DFG888?
The closer body measures 7.32 x 2.68 x 1.42 inches (186 x 68 x 36mm), so the pocket has to take that footprint plus the cement case. Base seat adjustment gives you +/- 0.12 inch (3mm) fore and aft, +/- 0.12 inch left and right, and 4 degrees of alignment, which is why the floor does not have to be preset dead accurate before the unit goes in.
3) Does the Cal-Royal DFG888 work on a door that swings both ways?
Double action, yes. The DFG888 opens 150 degrees in both the left and right direction, so it suits a center-hung glass door that swings in and out. It is not an offset-hung closer; for a 3/4 inch offset pivot arrangement you want a Norton Rixson 20 Series or 127 Series floor closer instead.
4) Should I order the DFG888 with hold-open or the non hold-open version?
Hold-open on this closer catches the door at 90 degrees, which is what you want on a retail or office entrance where deliveries and traffic need the leaf parked open. If the opening is on a fire-rated or smoke separation, or the door simply must self-close every cycle, order the DFG888-NHO non hold-open instead. Both are stock configurations, and both come in Duronodic and Satin Stainless Steel cover finishes.
5) I need a floor closer for an all-glass storefront door. Is the Cal-Royal DFG888 the right type?
For a frameless glass entrance leaf between 29.5 and 39.4 inches wide and under 220 lbs, yes. A concealed floor closer carries the door's weight at the bottom pivot and hides the mechanism in the slab, which is why glass entrances use them instead of an overhead closer that would need a header and a visible arm. If the leaf is heavier than 220 lbs or hung on 3/4 inch offset pivots, look at a heavy-duty body such as the Norton Rixson 127 Series.
6) What is the difference between the Cal-Royal DFG888 and the Dorma BTS80 floor closer?
They cover different scopes of supply. The Cal-Royal DFG888 is a concealed glass floor closer sold as a complete unit for all-glass commercial doors, rated for doors 29.5" - 39.4" wide and up to 220 lbs., with 150 degrees of double action opening and a 90 degree hold-open built in as stock. The Dorma BTS80 is a heavy duty closer body only from the BTS80 Series, so the cement case, spindle and any glass door patch fittings are ordered separately to complete it. If you want one part number that arrives ready to set in the floor under a glass leaf, the DFG888 is the one; if you are matching an existing BTS80 pocket and only the body has failed, the BTS80 replaces the body alone.
7) Our spec calls for a Grade 1 floor closer. What should we use instead of the Cal-Royal DFG888?
Two floor closers carry a stated Grade 1 rating. The Dorma BTS75V is a Grade 1 floor closer body supplied with its cement case, less spindle, in a non hold open function. The Norton Rixson H28 Series is a Grade 1 heavy duty concealed floor closer built for offset-hung doors. If the drawing names Grade 1 outright, quote one of those; the Cal-Royal DFG888 is the concealed glass floor closer for double action all-glass leaves up to 220 lbs. with a 90 degree hold-open, and it suits openings written around door weight and swing rather than a graded callout.
8) Can the Cal-Royal DFG888 be used on an offset-hung aluminum or hollow metal door?
The DFG888 is a concealed glass floor closer, engineered for commercial glass door installations in double action swing with 150 degrees of opening. For a door hung on offset pivots, the Norton Rixson H28 Series is a heavy duty Grade 1 concealed floor closer made for offset-hung doors, the Rixson 127 Series is a heavy duty 3/4" offset closer for deep reveal applications, and the Rixson 20 Series is a standard duty 3/4" offset hung closer with 180 degree door swing capability. Confirm the pivot offset on the frame before ordering, since the 3/4" offset units and the DFG888 are set up for different door hanging entirely.
9) Can the closing speed on the Cal-Royal DFG888 be adjusted after install?
Closing speed and braking speed are both adjustable on the DFG888, so you can slow the final latching action on a busy entrance or speed the sweep on a lighter leaf without pulling the unit. That matters on a glass door where a hard close puts stress on the patch fittings.
10) What finishes does the Cal-Royal DFG888 floor closer come in, and will they match my other entrance hardware?
Two cover finishes: Duronodic (dark bronze anodized) and Satin Stainless Steel. Both are offered with or without hold-open, so you can standardize a whole bank of entrance doors on one finish and still mix hold-open and non hold-open leaves where the building requires it. Satin stainless is the usual pick alongside stainless patch fittings and rails; Duronodic suits bronze anodized storefront.
11) Will the Cal-Royal DFG888 open a full 180 degrees?
No. The DFG888 tops out at 150 degrees of opening, in both directions. If the opening needs the leaf to swing flat back against the wall, a 180 degree closer such as the Norton Rixson 20 Series is the one to look at.
12) Do I need to order a separate cement case with the Cal-Royal DFG888?
No. The DFG888 is a concealed unit measuring 7.32" long, 2.68" wide and 1.42" thick, with a base seat adjustable plus or minus 0.12" backward and forward, plus or minus 0.12" left and right, and 4 degrees of alignment, so the floor does not have to be preset. Among the offset-hung floor closers the case is a separate line: the Norton Rixson 25 Series cement case is a heavy duty galvanized steel case ordered as its own package, and the Dorma BTS75V ships with its cement case but less spindle. That difference is worth catching at takeoff so a case does not end up missing from the order.
13) I need a non hold open floor closer. What are my options besides the Cal-Royal DFG888?
The DFG888 itself covers it: alongside the stock 90 degree hold-open, it is offered as DFG888-NHO in a non hold open build, in both Duronodic and Satin Stainless Steel finishes. If the opening calls for an offset-hung door rather than a glass leaf, the Dorma BTS75V is a Grade 1 floor closer body in NHO non hold open function, supplied with cement case, less spindle. For a stairwell, corridor or any door on a fire or smoke barrier, non hold open is usually the required choice.
14) Is the Cal-Royal DFG888 rated for a fire door?
The DFG888 is a commercial concealed glass floor closer with a 90 degree hold-open as its stock build, and hold-open is generally not what you want on a labeled opening. Among the floor closers, the Dorma BTS80 carries a fire rating of No. For a fire rated opening, work from the door and frame label first and confirm the closer with the authority having jurisdiction before committing hardware.
