4011-689 Pull Side Closer

Model 4011 is part of LCN's 4010 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: 4012, 4013, 4014, 4015, 4016.  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 4011.

Mounting

Model 4011 is designed to mount on the PULL side of the door only.  This special design limits your mounting options, but gives you a closer that maximizes performance.  Model 4011 is often used on heavier doors, or very high traffic doors.

It is common to see a mix of LCN models in a large building such as a hospital.  Standard doors will take the more 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.

Being a specialized closer, this model is handed.  Use the Images tab to view a handing diagram.
