Deltana DC50 Door Closer

Neither. The DC50 is a universal handed closer, so the same unit works on a left or right hand door. You pick handing at install by how you mount it, not on the order form. Only the finish has to be chosen when ordering.

UL Listed, yes, and Deltana classes the DC50 as a commercial product. That covers the listing itself; nothing in the DC50 record establishes a fire rating or an ANSI/BHMA grade, so if your spec calls out Grade 1, look at a closer that carries it outright, like the Cal-Royal 500S or the Arrow DC314 DC300 Series.

On the unit doors, likely; on the main entrance, no. The 75 lb load ceiling and fixed size #2 spring suit lighter interior and light commercial doors. Building entrances are normally heavier and get a medium or heavy duty closer, such as the Norton Rixson 8501A (Grade 1, adjustable size 1-6) or the Dormakaba 7414 (medium duty, Grade 1, size 1-4). Standardizing a fleet on one closer only works if every door in it falls under that 75 lb limit.

The Deltana DC50 is fixed at spring power size #2 with a 75 lb maximum load, so a heavier or wider leaf needs a closer with more spring. Heavy duty options include the BEST EHD9000 Series extra heavy-duty surface closer with adjustable spring sizes 1-6, the Sargent 1431 Powerglide heavy-duty surface closer with adjustable spring power, the Falcon SC71A Series heavy-duty surface-mount closer, and the LCN 1460T heavy duty surface-mounted closer in a powder coat finish. All four are Grade 1 except the LCN 1460T, which is listed as heavy duty in the 1460T Series.

The Deltana DC50 is a universal handed surface closer specified by size and finish rather than by a hold open arm function. For an opening that has to stand open, the Accentra 51 Series industrial closer carries a tri-packed hold open arm across sizes 1-6, and the Orca Hardware BHDC1958 series hold open closer ships with a parallel bracket for doors 1-3/4 inch thick. Both put the hold open in the arm itself, so it is set at the door rather than dialed in at the body.

The Deltana DC50 is a surface mounted closer with a die-cast aluminum body and stamped steel arm, set at spring power size #2 and UL listed for commercial use. Two light duty peers cover similar openings: the Norton Rixson 160 Series light commercial surface door closer with adjustable spring is Grade 1 light duty, and the BEST SL6000 Series is a Grade 1 light duty surface closer with adjustable spring sizes. Both of those adjust across a spring range rather than holding a single fixed power, so a door that needs more than a size 2 can be dialed up on either.

The Deltana DC50 is a UL listed commercial surface closer with a die-cast aluminum body, stamped steel arm, universal handing and a 75 lb maximum load at spring power size #2. The Corbin Russwin DC3200 is a Grade 1 surface closer in the DC3000 Series with a regular arm and a 1-3/4 inch door thickness. If the drawing calls out an ANSI/BHMA Grade 1 closer by name, the DC3200 and its DC5230, DC6200 and DC8200 stablemates are the ones written to that line, all Grade 1 for 1-3/4 inch doors.

Four: Aluminum, Duro, Gold, and White. That is the complete range on the DC50, so if you are matching closers across a building, one of those four has to work or you are into a different series.

The DC50 is a fully adjustable closer, so you can tune the closing action after it is on the door. What is not adjustable is spring power: it is a fixed size #2 unit. Closers with adjustable spring power, like the Accentra 1101BF (sizes 1-4) or the Arrow DCN325 (sizes 1-6), let you change the force at the opening instead.

Surface mounted. The DC50 body screws to the door or frame face with the arm reaching across to the other, so no door prep, no floor coring, and no concealed pocket in the frame. That makes it a retrofit option on an existing door that has never had a closer.

The Deltana DC50 is a universal surface mounted closer supplied in a set configuration. When the mounting position is not settled until the installer is at the frame, a tri-pack closer covers all three: the Dexter DCH1000 Series is a Grade 1 surface closer with tri mount for regular, parallel or top jamb mounting with a full cover, the Norton Rixson 1600 Series is a Grade 1 tri-mount closer with 180 degree swing, and the Arrow DCN325 is a Grade 1 surface closer with regular and parallel arm tri-pack and adjustable spring size 1-6.

No. The Deltana DC50 is a surface mounted door closer that controls the swing and closes the door. The Stanley Security 327 heavy wardrobe pivot and the Stanley 341 wardrobe pivot for flush recessed or overlay doors are hanging hardware, carrying the door for 1-3/8 or 1-3/4 inch and 1-1/8 to 1-3/8 inch leaves respectively. Likewise the Arrow DCN500DP parallel drop plate is a mounting bracket for the DCN500 closer, not a closer. None of the three will close a door on their own.

The Deltana DC50 body is die-cast aluminum with a stamped steel arm, and its substrate is aluminum throughout. For a door where a cast body is preferred, the Sargent 281 Powerglide is a cast iron surface closer with heavy-duty Grade 1 construction, and the LCN 1261 is a surface closer with cast iron construction and adjustable spring sizes 1-5, rated light to medium duty. Falcon's SC81A and SC61A use cast aluminum instead, at medium duty and light to medium duty.

The Deltana DC50 is offered in aluminum, duro, gold and white finishes at spring power size #2, specified by finish rather than by a delayed action function. For an opening that needs the door held back briefly, the Orca Hardware BHDC1958 delayed action closer and the BHDC2011 delayed action closer both come as a regular arm with parallel bracket, tri-packed non-hold open, for 1-3/4 inch doors.

The Deltana DC50 has a die-cast aluminum body and is UL listed for commercial use at size #2. For a storefront leaf specifically, the Norton Rixson 1600 Series aluminum storefront door closer uses tri-style mounting and is Grade 1 heavy duty in the 1600BC Series. The Falcon SC91A is a Grade 3 light duty cast aluminum surface closer, which sits at a different grade line than the Grade 1 storefront unit.

The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer, and the Deltana DC50 is a UL listed commercial surface closer at spring power size #2 with a 75 lb maximum load. They serve similar light commercial openings, but they are written differently on a spec: a job that calls for ANSI/BHMA Grade 1 will not take the Grade 2 unit, and needs something like the Calibre CA5501 standard arm surface closer or the Arrow DC314, both Grade 1.
