Adjustable Spring Power – Size 1–6

The 86 Series provides adjustable closing force from:

Size 1 through Size 6

This allows the installer to tune the closer for a wide variety of commercial door sizes, weights, and operating conditions.

Adjustable spring power makes the same closer suitable for applications ranging from lighter interior doors to heavier commercial entrance doors.

Tri-Pack Mounting

The Prime 86 Series is supplied in a versatile Tri-Pack configuration, allowing three common mounting styles from one closer package.

Regular Arm

Mounted on the pull side of the door.

This is one of the most common commercial closer installations and provides efficient mechanical operation.

Top Jamb

Mounted on the frame header on the push side of the opening.

Ideal where door-face mounting space or installation conditions make a standard regular-arm application impractical.

Parallel Arm

Mounted on the push side of the door with the arm positioned parallel to the door when closed.

Parallel-arm installation provides a cleaner appearance and helps reduce arm projection into the opening.

Adjustable Sweep Speed

The sweep-speed valve controls the primary closing portion of the door's travel.

This adjustment allows the installer to regulate how quickly the door moves through the main closing cycle.

Adjustable Latch Speed

The latch-speed adjustment controls the final portion of the closing cycle.

Proper adjustment helps provide enough closing force to:

• Engage the latch

• Overcome weatherstripping

• Close against air pressure

• Secure the opening consistently

while maintaining controlled door movement.

Adjustable Backcheck

Backcheck helps slow the door as it approaches the fully open position.

This can help reduce excessive opening force caused by:

• Heavy pedestrian traffic

• Wind

• Aggressive door operation

• Carts and equipment

• Sudden manual opening

Backcheck is designed to cushion the opening cycle, not serve as a mechanical door stop.

A proper wall or floor stop should still be used where required.

The final installation method depends on the door handing and selected mounting style.
