4041-691 Universal Closer

Model 4041 is part of LCN's 4040 series.

The last digit of the model number indicates spring size.  When the digit is a ''1'', it means the closer contains a universal spring, sized 2-6.

You can also order specific spring sizes: 4042, 4043, 4044, 4045, 4046.  But this is rarely done anymore since the ''1'' spring spans all the other sizes and is fully adjustable in the field.  This is why we only stock model 4041.

Bolt Holes

The easiest method for determining a closer model number is to measure the bolt hole pattern.

Mounting

Model 4041 is designed to mount on either side of the door.  The parallel arm bracket is included in the box, which is also called a Tri-Pak Mounting Kit.  Tri designating three methods of mounting the closer.

It is common to see a mix of LCN models in a large building such as a hospital.  Standard doors will take the universal model 4041 closer.  High traffic doors with closers mounting PULL side use model 4011.  If a high traffic door has a PUSH side mount, then model 4111 is used.

Using the mix of the 3 closer models allows for the best combination of ease of installation and long life.

Options:

Closers are available with the ''H'' hold open arm, but can only be used on non-fire rated doors.

DA closers are Delayed Action closers that contain an extra valve.  This valve holds the door open temporarily, allowing handicapped people more time to pass through the opening.  The DA valve is fully adjustable.

Handing:

Model 4041 is non-handed.

Arms:

Optional arms are available.
