Deltana DC70 Door Closer

Handing is not a factor. The DC70 is universal, so the same closer goes on a left-hand or right-hand door and you only need to pick the finish. For a property manager stocking a few spares across a building, that means one part number covers every opening.

No hold-open function is part of the DC70. It closes the door every time, which is what you want on a door that has to stay latched. If you need the leaf to stand open, look at a hold-open arm closer such as the Accentra 51 Series or the Orca BHDC1958HO, both of which are built with a hold open arm.

The DC70 is rated to a 140 lb maximum load at Spring Power Size #3, which puts a wide or heavy exterior leaf outside its range. For heavier doors, step to a heavy duty surface closer with a larger adjustable spring range: the BEST EHD9000 Series is an extra heavy-duty surface mounted closer with adjustable spring sizes 1-6 and Grade 1, the Sargent 1431 Powerglide is a heavy-duty surface closer with adjustable spring power and Grade 1, and the Falcon SC71A is a heavy-duty Grade 1 surface-mount closer. All three reach spring powers above the DC70's fixed size #3, which is what a heavier or wider door needs to latch reliably.

The DC70 is a surface mounted closer with a fixed Spring Power Size #3, a die-cast aluminum body and a stamped steel arm, rated to a 140 lb maximum load and UL and CUL listed. The nearest like-for-like light duty surface closers are the Falcon SC91A, a light duty cast aluminum surface-mount closer, and the Norton Rixson 160 Series light commercial surface closer with adjustable spring. Both sit in the same light duty surface-mounted class; the difference is that the DC70 is supplied at one fixed spring size while the SC91A and 160 Series are built around an adjustable spring, so on a mixed set of openings the adjustable units can be dialed per door and the DC70 is selected by matching the door to size #3.

The DC70 carries UL and CUL listing and is classed for commercial use, and it is ordered at a fixed Spring Power Size #3. When a drawing or spec calls out a Grade 1 closer by name, choose a peer that states Grade 1 directly: the Corbin Russwin DC3200 is a Grade 1 regular arm surface closer, the Cal-Royal 700S is a Grade 1 dual valve sized closer with adjustable tube arm, the Norton Rixson 8501A is a Grade 1 tri-mount surface closer with adjustable size 1-6 spring, and the Dexter DCH1000 Series is a Grade 1 surface closer with tri mount and full cover. For an institutional standardization program where every opening has to trace back to a stated grade, those are the units to write into the schedule.

The DC70 is a universal handed surface closer supplied with a stamped steel arm and no hold open function. When the opening has to stand open for deliveries, cart traffic or move-ins, use a closer built with a hold open arm: the Accentra 51 Series is a tri-packed hold open arm closer covering sizes 1-6, the Orca Hardware BHDC1958HO/PA is a hold open closer with a parallel bracket for 1-3/4 inch doors, and the Stanley Security A45-501HL is supplied with a long hold open arm for top jamb mounting. Choosing hold open is an arm decision, so it has to be made at the time of order rather than added to a closer later.

The DC70 is a commercial surface mounted closer rated to a 140 lb maximum load at Spring Power Size #3, sized for doors within that weight. A full aluminum storefront entrance with a narrow top rail is a different problem: the Norton Rixson 1600 Series aluminum storefront closer is a heavy duty Grade 1 unit with tri-style mounting made for that application, and the Dorma 8916-JT is a heavy duty Grade 1 jamb track closer for frame face, pull side mounting with adjustable size 1-6 spring, which suits openings where a track arm is wanted instead of a projecting arm. Glass front installers working storefront should specify from those rather than a fixed size #3 unit.

The closing action is fully adjustable on the DC70. The spring power itself is fixed at size #3 with a 140 lb door limit, so what you are tuning is the hydraulic action, not the power. If the opening needs a different spring size, you want an adjustable-size closer instead.

Die-cast aluminum body with a stamped steel arm. Aluminum keeps it light enough for residential and light commercial doors, but if you are putting a closer on a high-traffic entrance or an abuse-prone opening, a cast iron body such as the Sargent 281 Powerglide or the LCN 1261 is the tougher build.

Four finishes on the DC70: Aluminum, Duro, Gold, and White. White and Aluminum are the ones that disappear against a typical painted or aluminum frame; Gold is the one to pick if you are matching brass-tone lever trim already on the openings.

For a fleet of similar interior doors, yes, and the reason is the fixed spec: size #3, 140 lb limit, universal handing, one SKU per finish. You are not sizing each opening or ordering left and right versions. Where it breaks down is any door over 140 lbs or an exterior leaf catching wind, and for those a closer with adjustable spring sizes is the better standard.

The DC70 is a surface mounted closer with universal handing and a fixed Spring Power Size #3. When the mounting position is still open on the drawing, a tri-pack closer ships the brackets for more than one position: the Arrow DCN325 is a Grade 1 surface closer with regular and parallel arm tri-pack and adjustable spring size 1-6, the Dexter DCM1000 Series is a Grade 1 surface closer with tri mount covering regular, parallel or top jamb, and the Dormakaba 8616 AF86P FC SNB1 689 is a Grade 1 closer with a flat non-hold open arm supplied tri-pack. Buying tri-pack keeps one part number good whether the closer lands on the pull side, the push side or the frame face.

Both are commercial hydraulic surface closers, but they are described by different measures. The DC70 is specified by spring power and load: fixed Spring Power Size #3, a 140 lb maximum load, die-cast aluminum body with a stamped steel arm, UL and CUL listed. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, and the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check. If the deciding factor is a stated ANSI grade on a purchase spec, the Cal-Royal units carry one; if the deciding factor is matching a known door weight and a UL listing, the DC70's 140 lb rating and UL and CUL listing are the figures to work from.

No. The DC70 is a complete surface mounted door closer with a die-cast aluminum body and stamped steel arm. The Arrow DCN500DP is a parallel drop plate for the DCN500 - a mounting bracket that lowers the closer body on the frame or door face so a parallel arm installation clears the stop or the frame face. It contains no hydraulics and closes nothing on its own. A drop plate is ordered alongside a closer when the mounting surface is too narrow, never in place of one.

The DC70 is a fixed Spring Power Size #3 surface closer with universal handing and a stamped steel arm; it does not offer a delayed action function. Where an opening serves slower traffic and the door needs to stay open longer before it begins to close, specify a delayed action unit: the Orca Hardware BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket for 1-3/4 inch doors, and the Orca BHDC2011DA/PA is the same delayed action arrangement in the BHDC2011 Series. Both are tri-packed non-hold open arm closers, so the mounting position can still be chosen at install.

No. The DC70 is a surface mounted door closer that controls the swing and closing of the door. 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 from 1-1/8 inch to 1-3/8 inch. Pivots carry the weight of the leaf and set its axis of rotation; they do not close it. A pivot-hung door still needs a closer if it has to self-close.

The DC70 is offered in Aluminum, Duro, Gold and White over a die-cast aluminum body. When a property manager is matching an existing run of closers on a different appearance, closers whose finish treatment is called out include the Dormakaba 7303 Series standard duty closer in a painted finish and the LCN 1460T heavy duty closer in a powder coat finish. Both are surface mounted like the DC70, so the mounting approach on the door stays familiar while the exposed cover or body appearance changes.
