LCN Door Closers and Automatic Operators in Indianapolis, IN.

Commercial Door Closers

Door closers control closing speed and help return a door to the latched position after use. LCN offers surface-mounted, overhead-concealed and other specialized closer configurations for different architectural and performance needs.

Surface-mounted closers are common because they are accessible for adjustment and available with multiple arm and mounting options. Concealed closers may be selected when appearance or limited surface hardware is a priority, but the door and frame must be designed to accommodate them.

The closer must have enough power to control the door without making it unnecessarily difficult to open. Adjustment should account for sweep speed, latch speed, backcheck and delayed action where those features are available and appropriate.

Fire and Life-Safety Door Control

Closers are critical components on many fire-rated doors because the opening must return to a closed and latched position. LCN offers products for fire and smoke barrier applications, including closer and holder systems in approved configurations.

Propping open a rated door with an unapproved wedge or stop can prevent it from performing as intended. Where a door needs to remain open during normal use, a listed hold-open system connected to the required release controls may be necessary.

LCN Automatic Door Operators

Automatic operators can help make entrances and interior doors easier to use for people with disabilities, older adults, employees moving equipment and visitors carrying items. LCN offers electromechanical, electrohydraulic and pneumatic operator options for different traffic levels, mounting conditions and use patterns.

Low-energy operators are commonly activated by a push plate, wave switch or compatible access-control signal. Some products are designed primarily for manual use with occasional automatic opening, while others support openings that operate automatically more frequently.

Accessibility and Touchless Operation

An automatic operator alone does not make an entire entrance accessible. Clear opening width, threshold height, maneuvering clearance, hardware operation, activation location, closing timing and approach conditions must all be considered.

Touchless activation can also help users move through an opening without contacting a handle or push plate. The activation method, safety controls and sequence of operation should be selected according to the building and expected users.

Choosing the Correct LCN Product

Closer and operator selection begins with accurate opening information. Useful details include the door width, height, thickness, weight, material, handing, hinge or pivot type, frame construction, interior or exterior location, expected traffic and available power.

Exterior doors in Indianapolis may need additional closing force because of wind and building pressure, but excessive force can create accessibility or usability problems. The opening should be evaluated as a system, including weather seals, latch, hinges, threshold and air pressure.
