TownSteel TDC-70-AL – Frequently Asked Questions

1) Do I have to order a TownSteel TDC-70 door closer handed for a left or right hand door?
No handing to specify. The TDC-70 closer body is a non-handed aluminum casting, so one unit works on either a left or right hand door. What you do pick is the arm: regular arm, parallel arm with CUSH stop, hold open parallel arm, hold open CUSH parallel, or delayed action. That choice is driven by which side of the door you are mounting on and whether you want the door to stop or stay open, not by the swing of the door.
2) Will one TownSteel TDC-70 closer cover both a light interior door and a heavy exterior entrance?
Spring power on the TDC-70 is adjustable through sizes 1 to 6, so a single closer covers narrow interior doors up through wide exterior entrances. That is why it is the one to stock if you are standardizing across a building with mixed door sizes: you set the power at install instead of ordering a different size per opening. TownSteel rates the series for heavy traffic, exterior or interior, at ANSI/BHMA Grade 1.
3) Which TDC-70 arm do I order if the door swings out and there is no room on the pull side?
Take a parallel arm version. On an out-swinging door you mount on the push side, and the TDC-70 parallel options are the CUSH arm (which builds the stop into the arm, so you do not need a separate floor or wall stop) and the hold open parallel arm. The plain regular arm mounts on the pull side of the door and is the wrong pick for that opening. If you want both the built-in stop and a hold open, the hold open CUSH parallel arm combines them.
4) Is the TownSteel TDC-70 closer ADA compliant for a barrier free opening?
Yes. TownSteel states the TDC-70 series is barrier free and ADA compliant, and the size 1 to 6 spring adjustment is what gets you there: you dial the power down to meet the opening force limit on an accessible interior door, then still have the range to handle a heavier exterior leaf elsewhere in the building.
5) What is a straight equivalent to the TownSteel TDC-70 door closer from another brand?
The closest peers are Grade 1 surface mounted closers built for medium duty commercial openings. The Sargent 1331 is a Grade 1 medium duty surface door closer with a universal aluminum body, and the Norton Rixson 8501A is a Grade 1 medium duty tri-mount surface closer with an adjustable size 1-6 spring, which matches the TDC-70's adjustable spring power range. The BEST HD7000 Series is another Grade 1 medium duty surface closer with adjustable spring power and backcheck control. All three cover the same class of interior and exterior commercial door the TDC-70 is specified for.
6) What door closer should I use instead of the TDC-70 on a high traffic exterior entrance that takes abuse?
Step up to a heavy duty Grade 1 body. The BEST EHD9000 Series is an extra heavy duty Grade 1 surface closer with adjustable spring sizes 1-6, the Sargent 1431 Powerglide is a heavy duty Grade 1 surface closer with adjustable spring power, and the Falcon SC71A is a heavy duty Grade 1 surface mount closer. The Sargent 281 Powerglide uses cast iron heavy duty construction rather than the aluminum cast body the TDC-70 uses. All keep the Grade 1 certification the TDC-70 carries while moving up a duty class.
7) I need a delayed action closer so residents have time to get through the door. What else offers that besides the TownSteel TDC-70?
The TDC-70 offers a delayed action option with an adjustable delayed action closing valve. Among other brands, the Orca Hardware BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket, and the Orca BHDC2011DA/PA is a delayed action closer in the same configuration. Both are tri-packed non-hold open arm closers for 1-3/4 inch doors. Delayed action is the feature to confirm on any substitute, because it is an option on the body rather than something an arm change adds later.
8) I need a hold open closer. What can I use besides the TownSteel TDC-70 hold open arm versions?
The TDC-70 covers hold open with both a hold open parallel arm and a hold-open CUSH parallel arm. For hold open from other brands, the Accentra 51 Series is an industrial closer with a tri-packed hold open arm and size 1-6 adjustable spring, and the Orca Hardware BHDC1958HO/PA is a hold open closer with a parallel bracket for 1-3/4 inch doors. Confirm the hold open is a factory arm rather than a field add, since the arm determines whether the door stays put at the open position.
9) The architect's drawing calls for a concealed or slide track closer. Does the TownSteel TDC-70 meet that, and what does?
The TDC-70 is a surface mounted closer with regular arm, parallel arm, and CUSH parallel arm options, so a drawing calling for a track arm needs a track closer. The Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard, pull side mounting, for 1-3/4 inch doors, and the Dorma 8916-JT is a Grade 1 heavy duty jamb track closer with frame face mounting, pull side, adjustable size 1-6. Both put the arm in a track rather than in a projecting linkage.
10) My spec requires an ANSI Grade 1 closer. Which alternatives to the TDC-70 also meet Grade 1, and which do not?
The TownSteel TDC-70 is ANSI/BHMA Grade 1. If a substitute has to hold that certification, the Corbin Russwin DC8200, the Dexter DCH1000, the Cal-Royal 500S, and the Calibre CA9901 are all Grade 1 surface closers. Two peers that get quoted as closer substitutes do not carry Grade 1: the Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, and the Falcon SC91A is Grade 3. On a job where the submittal names Grade 1, those two will not clear review even though they hang on the same door.
11) What looks like a substitute for the TownSteel TDC-70 closer but is not one?
The Arrow DCN500DP is a parallel drop plate for the DCN500 closer, not a closer itself. It is a mounting accessory, so ordering it in place of a TDC-70 leaves you without the closer body. Also check cover: the Arrow DCN314 and DCN325 are Grade 1 surface closers supplied less cover, while the Dexter DCH1000 is supplied with a full cover. On a finished lobby or storefront the exposed body changes the appearance, which is part of why the TDC-70 is specified for openings that need both appearance and reliability.
12) The TownSteel TDC-70 is barrier free and ADA compliant. What other closers meet that?
The TDC-70 is barrier free and built for ADA compliance. Comparable ADA and barrier free closers include the Cal-Royal 500S, a Grade 1 barrier free closer with adjustable back-check; the Cal-Royal N900PBF, a barrier free Grade 1 hydraulic surface closer; the Calibre CA9901, a Grade 1 ADA surface mount closer with a tri-pack arm in size 2-5; the Calibre CA4001, a Grade 1 adjustable spring tension ADA hydraulic closer; and the LCN 1250, a light duty closer with all-weather fluid. Barrier free operation depends on adjusting the spring down to the opening force the door requires, so confirm the size range covers your door.
13) What is the delayed action option on a door closer actually for?
Delayed action holds the door open at the wide part of the swing for a few seconds before the closer begins its normal sweep, so someone pushing a cart, a bed, or an armload of stock gets through before the door starts back. On the TDC-70 it is an adjustable valve and it is ordered as its own arm configuration. Hospitals and any opening with wheeled traffic are where it earns its keep. If nobody needs extra crossing time, the standard regular arm is the simpler order.
14) Should I use a hold open closer or a closer with a separate door stop?
A hold open arm keeps the door parked open where you set it, which is what you want at a receiving door or a room being aired out. A CUSH arm does something different: it stops the door at the arm so the leaf never slams into an adjacent wall, but it still closes. The TDC-70 offers each on its own and a hold open CUSH arm that does both. One caution: a hold open closer should not go on a fire rated opening that needs to self close.
15) I need a delayed action closer. Is the TownSteel TDC-70 the only option?
No. TownSteel offers delayed action on the TDC-70 as an ordered configuration in both aluminum and Duro finish. Orca Hardware also lists delayed action closers, the BHDC1958 Series delayed action with regular arm and parallel bracket and the BHDC2011 Series delayed action, both stated for 1-3/4 inch doors. The Orca units come tri-packed with a non hold open arm, so mounting flexibility is built into the box rather than chosen when you order.
16) Is the TownSteel TDC-70 heavy enough for a hospital corridor or a busy storefront?
That is the exact application TownSteel builds it for. The TDC-70 is a Grade 1 medium to heavy duty closer aimed at hospitals, storefronts, business offices, and cafes, places where the closer is on show and cycles all day. Needle bearing construction in the body is what carries the cycle count. For a hospital corridor specifically, the delayed action version is worth ordering so beds and carts clear the opening.
17) What does ANSI/BHMA Grade 1 mean on a door closer, and does the TDC-70 have it?
The TDC-70 series carries ANSI/BHMA Grade 1, the highest of the three grades in the standard and the one written into most commercial and institutional specs. On closers it means the unit passed the top cycle and performance tier rather than the lighter Grade 2 or Grade 3 tiers. If your drawing calls for Grade 1 surface closers, this series meets that line. For contrast, a Grade 2 closer like the Cal-Royal 400 Series would not.
18) Is there a simpler door closer than the TDC-70 for a low traffic interior office door?
For light traffic interior openings, the Arrow DC314 is a light duty Grade 1 surface mounted closer, the BEST SL6000 Series is a light duty Grade 1 surface closer with adjustable spring sizes, and the Norton Rixson 160 Series is a light duty Grade 1 light commercial surface closer. The Falcon SC91A is a light duty cast aluminum surface closer certified to Grade 3 rather than Grade 1. The TDC-70 is built for medium to heavy duty traffic, exterior or interior, so a light duty body is the narrower choice where the door sees occasional use.
19) I have to standardize closers across a whole facility. Which alternatives to the TDC-70 also adjust across the full size 1-6 range?
Adjustable spring power across sizes 1 through 6 lets one part number cover interior offices and exterior entrances, which is why it matters for standardizing. The TownSteel TDC-70 adjusts from size 1 to 6. Peers with the same range include the Accentra 2701 Series, the Norton Rixson 8501A, the BEST EHD9000 Series, the Arrow DCN325, the Imperial USA TC4300 Series, and the LCN 1450. Closers limited to sizes 1-4, such as the Accentra 1101BF and the Dormakaba 7414, cover a narrower band of door widths and weights.
20) I need a non-handed closer that can mount regular, parallel, or top jamb. Which options besides the TDC-70 do that?
The TDC-70 has a non-handed aluminum cast body, so one unit covers either hand of door. For tri-mount flexibility, the Dexter DCH4000, DCL2000, and DCM1000 are Grade 1 surface closers that mount regular, parallel, or top jamb. The Norton Rixson 1601P is a Grade 1 medium duty tri-mount closer with 180 degree swing, and the Accentra 1101BF and 2701 Series ship tri-packed with a non-hold open arm. Tri-mount matters when you are stocking one closer for doors that open different directions.
21) How does the TownSteel TDC-70 differ from a cast iron door closer?
The TDC-70 uses a heavy-duty aluminum cast body with needle bearings and a slimline profile. Cast iron peers include the Sargent 281 Powerglide, a heavy duty cast iron surface closer, and the LCN 1261, a light to medium duty closer with cast iron construction and adjustable spring sizes 1-5. Aluminum body peers in the same class include the Sargent 1331 with a universal aluminum body and the Falcon SC81A, a medium duty cast aluminum closer. Body material is worth settling before you order, since it drives the look of the closer on the door as well as the weight the installer handles.
22) What closer should I put on an aluminum storefront door instead of the TownSteel TDC-70?
The TDC-70 is specified for storefronts among other commercial openings. If you want a closer built specifically around aluminum storefront, the Norton Rixson 1600BC Series is a heavy duty Grade 1 aluminum storefront closer with tri-style mounting. The Falcon SC61A is a light to medium duty Grade 1 cast aluminum surface closer, and the Dormakaba 7303 is a Grade 1 medium duty standard duty surface closer in a painted finish. Narrow top rails on storefront doors are the constraint to check against the closer body and mounting.
23) The TDC-70 CUSH arm stops the door. What other closers give me a stop in the arm?
The TownSteel TDC-70 offers a CUSH parallel arm and a hold-open CUSH parallel arm, both of which cushion and stop the door in the arm itself rather than relying on a separate wall or floor stop. Among peers, closers supplied with a flat arm include the Dormakaba 8616 with a flat arm non-hold open tri-pack and the Dorma 8916-JT with a flat non-hold open arm. If a substitute arm does not include a stop, plan on a wall stop or overhead stop to protect the door and the closer.
24) What are the medium to heavy duty alternatives to the TownSteel TDC-70 if I want to stay in the same duty class?
The TDC-70 is a medium to heavy duty closer. Peers in that same band include the Design Hardware 316 Series, a medium to heavy duty closer with a cover and a tri-packed non-hold open arm, and the Design Hardware 116 and 416 Series, both heavy duty with tri-packed non-hold open arms. The BEST HD8000 Series is a heavy duty Grade 1 surface closer, and the LCN 1460T is a heavy duty Grade 1 commercial closer in a powder coat finish. These sit between the light duty bodies and the extra heavy duty ones for doors that see steady daily traffic.
25) Can I match a Corbin Russwin closer that is already on my other doors instead of using the TDC-70?
If the rest of the building is Corbin Russwin, the DC3200 is a Grade 1 regular arm surface closer for 1-3/4 inch doors, the DC6200 and DC8200 are Grade 1 surface closers with a double lever regular arm and pull side mounting for 1-3/4 inch doors, and the DC5230 is Grade 1 with a slide track arm. All four hold the same Grade 1 certification as the TownSteel TDC-70, so matching the existing brand does not cost you the grade on the submittal.
26) What finishes does the TownSteel TDC-70 door closer come in?
Two: AL aluminum and DU Duro. Both are offered across every arm configuration, so you can run the same finish whether the opening takes a regular arm, a CUSH parallel, a hold open, or delayed action. That matters when you are closing out a corridor of doors and want the covers to match.
27) Can I use the TownSteel TDC-70 as a residential front door closer?
It is built and rated as a commercial closer, so it will work mechanically on a house door but it is more closer than a home needs and the aluminum body and exposed arm read industrial. Where it makes sense residentially is multi-family: apartment corridor doors, stairwell doors, and common area entrances all take the same abuse as a commercial opening, and the size 1 to 6 adjustment lets you set a light interior unit door and a heavier building entrance from the same part number.
