Closing Cycle Analysis

SLAM! Sweep Speed Latch Speed

Mastering the Arc

A door is a machine. If allowed to slam, it destroys itself and the frame. If too weak, it fails to latch, compromising security and fire safety. We engineer the perfect closing curve.

1

Sweep Speed

Controls the main closing swing. Fast enough to close, slow enough for safety.

2

Latch Speed

The final few inches. Gentle deceleration to engage the latch silently without impact.

3

Backcheck

Hydraulic braking when opening to prevent the door from slamming into the wall behind it.

Professional Door Closer Installation That Prevents Damage and Meets Code

Commercial door closers do more than close doors - they control closing speed to prevent damage, ensure fire doors latch during emergencies, meet ADA accessibility requirements, save energy by ensuring positive closure, and extend door hardware lifespan.

South Austin Locksmith provides professional installation of top brands like LCN, Norton, and Yale.

Why Professional Installation Matters

The Risks of Improper Adjustment

Safety & Code Violations

Closers that slam can crush fingers and damage frames. Leaking closers create slip hazards. Excessive opening force violates ADA (~$50k+ fines).

Benefits of Professional Service

🛡️

Fire Compliance

We ensure fire doors latch positively from any open position (NFPA 80 requirement).

Secure
🛡️

ADA Accessible

We adjust opening force to ≤5 lbs so your building is accessible to everyone.

🛡️

Energy Savings

Proper latching prevents AC loss and drafts, lowering utility bills.

Door Closer Types

Overhead Regular Arm

  • Best For: Most standard commercial doors.
  • Features: Durable, easy to service, cost-effective.

Concealed Overhead

  • Best For: Upscale offices, aluminum storefronts.
  • Features: Hidden in header for clean look.

Automatic Operators

  • Best For: Handicap accessibility.

Our Installation & Adjustment Process

1

Sizing & Selection

We measure door weight and wind load to select the correct closer size (1-6).

2

Precision Mounting

We use through-bolts on hollow metal doors to prevent screws stripping out over time.

3

Hydraulic Tuning

We adjust Sweep Speed (closing), Latch Speed (final 10°), and Back-check (opening cushion).

4

Force Verification

We test opening force with a gauge to ensure ADA compliance.

Common Applications

Frequently Asked Questions

How do I know if my door closer is properly adjusted?
A properly adjusted closer closes the door at controlled speed (3-5 seconds from 90° to latch), positively latches without slamming, operates with ≤5 lbs force (ADA requirement), and has back-check to prevent the door from slamming into walls when opened quickly. Test: Open door to 90°, release - it should close smoothly without stopping mid-swing, latch positively, and not slam. If door doesn't latch (stops before closing), closes too fast (slams), or requires excessive force to open, adjustment is needed. Fire doors must close and latch from any position - test from fully open position.
What's the difference between overhead and floor-spring closers?
Overhead closers mount on the door or frame above the door, use hydraulic fluid in a visible cylinder. Advantages: easier service, lower cost ($180-$550), more models available. Floor-spring closers install in a pocket cut into floor below door pivot, completely concealed except for small cover plate. Advantages: invisible for clean aesthetic ($650-$1,200), better for heavy glass doors, preferred for upscale commercial entrances, can support door weight (center-hung pivots). Floor-springs cost more due to floor cutting, waterproofing, and installation complexity. Use overhead for most applications, floor-spring when appearance justifies premium cost or door construction requires it.
Can automatic door operators be added to existing doors?
Yes, most existing commercial doors can be retrofitted with automatic operators. Requirements: Door must be in good condition with proper closing force, adequate header space for operator mounting (6-8 inches clearance), electrical power near door (120V), ADA-compliant activation (push button, motion sensor, touchless), safety sensors to prevent entrapment. Two types: Low-energy operators open doors slowly (ADA compliant for power-assist), full-power operators open doors quickly (require safety sensors per ANSI A156.10). Typical installation costs $1,800-$2,800 including operator, activation device, power wiring, and programming. Building permit often required.
How often do commercial door closers need maintenance?
Maintenance frequency depends on traffic level and environment: High-traffic (100+ cycles/day): Quarterly inspection and adjustment. Medium-traffic (30-100 cycles/day): Semi-annual service. Low-traffic (<30 cycles/day): Annual maintenance. Exterior doors: More frequent (weather exposure accelerates wear). Fire doors: Annual inspection required by NFPA 80, documentation mandatory. Signs needing immediate service: Door doesn't latch, closes too slowly/quickly, leaking hydraulic fluid, requires excessive opening force, grinding/squealing noises. Regular maintenance ($120-$180 per closer) prevents failures and extends closer life to 15-20 years. Neglect reduces lifespan to 5-7 years.
Why does my door slam or won't close all the way?
Door slamming: Sweep speed valve too fast - hydraulic fluid flows through sweep circuit without enough restriction, door slams at end of swing. Fix: Adjust sweep valve clockwise to slow final 15° of closing. Takes 2-3 minutes. Won't close/latch: (1) Latch speed valve too slow - door closes to 3 inches then stops, doesn't overcome latch friction. Fix: Turn latch speed valve counter-clockwise slightly. (2) Closer power too low - door closes partially but lacks force to latch. Fix: Increase spring tension (turn power adjustment clockwise). (3) Misaligned strike or latch - mechanical binding. Fix: Adjust strike position. (4) Low hydraulic fluid - internal leak. Fix: Closer replacement needed (can't refill closers). Proper adjustment: Sweep speed 3-5 seconds, latch speed 1-1.5 seconds, positive latching without slam.
What type of closer do I need for a fire-rated door?
Fire-rated doors require UL-listed closers rated for the door's fire rating: 20-minute, 45-minute, 90-minute, 3-hour. Critical requirements: (1) Closer must be UL listed for fire assembly. (2) No hold-open feature unless connected to automatic fire alarm release (magnetic hold-open allowed with smoke detector release). (3) Must close door from any open position - self-closing from fully open. (4) Positive latching required - door must latch without assistance. (5) Fusible link hold-open prohibited (outdated, no longer code-compliant). (6) Adjustable back-check acceptable if closer UL listed with it. Common violations: Non-fire-rated closer on fire door, hold-open with doorstop (prevents closing during fire), improper adjustment (won't latch), damaged closer still in use. Fire marshal inspections verify these. Use LCN 4040/4110 series, Norton 8000 series, or Yale 3400 series for fire doors.
