Commercial Door Hardware Supply and Installation in New York City

Commercial door hardware on a New York City storefront or office building takes a beating every single day. High-traffic aluminum and glass doors need panic bars, closers, and exit devices that are specified correctly, installed to NYC DOB requirements, and built to last. Liberty Door Supply supplies and installs commercial door hardware across all five boroughs - Manhattan, Brooklyn, Queens, the Bronx, and Staten Island - as part of full storefront fabrication scopes and as standalone hardware replacements on existing doors.

What types of commercial door hardware does Liberty Door Supply install?

We install the full range of mechanical hardware used on aluminum storefront doors, glass vestibule entries, and commercial wood or hollow-metal doors in multi-tenant buildings. The hardware categories we work with include:

• Panic bars and exit devices: Von Duprin 99 and 98 series, Detex ECL-230D surface-mounted exit alarms, and Von Duprin QEL quiet electric latch retraction devices for coordinate use with automatic openers.
• Surface-mounted closers: LCN 4040XP and 4111 series, Norton 7500 series, and Dorma TS 93G for heavy-use aluminum storefront doors. We select closing force and backcheck based on door width and wind exposure - a real factor on corner storefronts in areas like Midtown Manhattan or along the waterfront in Red Hook, Brooklyn.
• Push/pull hardware: Rockwood and Trimco pull bars, push plates, and offset pulls specified to match your storefront framing finish - clear anodized, dark bronze, or custom powder coat.
• Door coordinators and flush bolts: Required on paired aluminum doors where a panic device is installed on the active leaf. We install Von Duprin and Ives door coordinators so the inactive leaf closes first every time, preventing misalignment and latch failures.
• Overhead stops and holders: Rixson and Glynn-Johnson overhead stops protect door frames in high-traffic vestibules and prevent damage to adjacent glass sidelites.
• Thresholds and door bottoms: Pemko and National Guard Products thresholds and adjustable door bottoms, selected for ADA-compliant maximum rise and correct weathertight seal on exterior aluminum frames.

Every hardware selection starts with the door type, the traffic load, and the applicable NYC Building Code section. We do not guess at sizing. We spec it, fabricate or source it, and install it correctly the first time.

How does ADA compliance affect commercial door hardware selection in New York City?

ADA Title III and New York City Local Law requirements govern operating force, hardware height, and closer sweep timing on any door serving the public. For storefront owners and property managers in NYC, this is not optional and inspectors enforce it.

The key rules that affect hardware selection are straightforward:

1. Interior doors must open with no more than 5 lbf of force. Exterior doors have a separate standard based on conditions, but closers must still be adjusted to the slowest compliant sweep speed.
2. Hardware must be operable with a closed fist - no tight pinching or twisting. That rules out knob hardware on ADA-required accessible doors. Lever trim on panic devices or push/pull sets is standard.
3. Operable hardware must be mounted between 15 inches and 48 inches above the finished floor.

We install LCN 4040XP closers with Cush-N-Stop arms and set backcheck and sweep speed to ADA sweep timing. On doors requiring automatic operation, we coordinate the mechanical hardware with the automatic door opener, though the opener itself is a separate scope. The panic bar trim and push side hardware still need to be correct regardless of whether a door is manually or automatically operated.

NYC DOB plan examiners and special inspectors look at hardware as part of storefront approval on new construction and alteration jobs. We produce hardware cut sheets and shop drawings when your GC or architect needs them for the filing package.

When should a property manager replace commercial door hardware versus the entire door?

The answer depends on the condition of the aluminum door frame and the door slab itself. Hardware is almost always worth replacing on its own if the frame is plumb, the hinges are solid, and the aluminum is not bent or corroded through. A failed closer or a worn-out panic bar on an otherwise sound aluminum storefront door is a straightforward swap.

You should plan for a full door and frame replacement when:

• The aluminum frame is racked, bent, or pulling away from the masonry or curtain wall opening.
• The bottom rail of the door is cracked or the glass stop is failing, which is common on older storefronts in high-foot-traffic corridors in areas like the Bronx Hub or Jamaica, Queens.
• The existing frame does not have the correct reinforcement to accept the new hardware. Older storefront framing sometimes lacks the blocking or steel backup plates required for Von Duprin through-bolt panic devices.

When hardware replacement alone is the right call, we can typically complete the work in a single visit with minimal disruption to tenants or customers. When a full door replacement is needed, we fabricate new aluminum frames and doors in-house and coordinate installation to minimize storefront downtime.

Frequently asked questions

Do you supply and install hardware on aluminum storefront doors?

Yes. We fabricate aluminum storefront frames and doors in-house and install the hardware as part of the same scope. That includes panic bars, surface closers, and push/pull sets on single or paired aluminum doors.

Can you replace hardware on an existing commercial door without replacing the door itself?

In most cases, yes. We assess the existing frame and door condition first. If the door and frame are sound, we can retrofit new panic hardware, a new closer, or new push/pull sets without a full door replacement.

Do you serve all five New York City boroughs?

Yes. Liberty Door Supply installs commercial door hardware in Manhattan, Brooklyn, Queens, the Bronx, and Staten Island. We work on retail storefronts, office buildings, schools, and multi-tenant properties citywide.
