Pull side, on door face
ANSI/BHMA A156.4 · UL 10C · ADA
Maryland, DC & Northern Virginia
A regular arm door closer mounts on the pull side of the door, with its arm reaching out to a shoe on the frame. This standard arm position gives the closer its full rated power, so heavy or drafty doors close and latch firmly. It is the most common closer setup for interior offices, storage rooms, and back-of-house doors. King Locksmith and Doors installs regular arm closers sized to your door weight, width, and traffic, and tuned to meet ADA and local fire code rules.
The arm works at full leverage, so heavy doors close and latch without slamming or sticking.
Fewer brackets and a simple template mean faster installs and lower labor costs for each opening.
Separate valves control sweep, latch, and backcheck, so we can fine-tune speed for almost any door.
King Locksmith and Doors Inc. is a commercial door and hardware company serving Maryland, Washington DC, and Northern Virginia. Our trained technicians install, repair, and replace door closers for small businesses, government agencies, hospitals, hotels, schools, and property managers. We carry grade 1 closers from trusted brands and stock common parts on our trucks. Whether you need one closer fixed or a full building upgrade, we show up on time and finish the job right.
The right regular arm closer depends on your door, your traffic, and the codes that apply to your building. Use these five factors to pick a closer that works smoothly and lasts for many years.
Closers are rated by spring size, from 1 to 6. A larger door needs a stronger spring to close and latch. Most interior doors around 36 inches wide use a size 3 or an adjustable 1–6 closer.
Heavy doors, wide doors, and doors with gaskets or smoke seals need more power. We check the width, weight, and hardware on every door before we pick a closer, so it never slams shut or fails to latch.
ANSI/BHMA A156.4 sorts closers into three grades. Grade 1 closers pass the longest cycle test and suit busy lobbies, hospitals, schools, and government buildings. Grade 2 and 3 closers fit lighter-use doors.
Choosing a low grade for a busy door leads to oil leaks, loose arms, and early replacement. For most commercial openings in the DMV, we recommend a grade 1 closer with a cast iron or aluminum body that holds up for many years.
A regular arm closer mounts on the pull side of the door. That means the closer body and arm face the room or hallway the door swings into.
This works well for interior offices, restrooms, and storage rooms. For exterior doors or public corridors where you want the arm hidden from view or out of reach, a parallel arm closer on the push side may be the better choice. We will tell you which fits.
ADA rules limit opening force on interior doors to 5 pounds and require at least 5 seconds to close from 90 to 12 degrees. A properly sized and adjusted closer meets both.
Fire-rated doors must self-close and latch under NFPA 80, so they need a UL-listed closer with no hold-open arm unless it is tied to the fire alarm. We set up every closer we install to meet code and pass your next fire inspection.
Backcheck slows the door as it opens so it does not slam into walls. Delayed action slows the first part of the closing swing, giving wheelchair users, carts, and hospital beds more time to pass.
Hold-open arms can keep non-rated doors propped open safely during busy hours. Finishes like aluminum, bronze, and black help the closer match your door hardware. We help you pick the right mix of features for each door and your budget.
Regular arm and parallel arm closers both control a door, but they mount differently. Here is how a regular arm closer compares on closing power, install cost, and daily performance.
Consideration
Regular Arm Closer
Parallel Arm Closer
Delivers full rated power to the door
Loses leverage, often needs a larger size
Simple template with fewer mounting parts
Needs an extra parallel arm bracket or shoe
Lower hardware and labor cost per opening
Extra parts and labor raise the price
Strong leverage helps doors latch every time
Weaker leverage can struggle against drafts
Simpler setup means quicker, cheaper adjustments
More parts to check during each service
