• Very little or no hardware projecting beyond the frame face, when in closed position, in most situations

Top Jamb

• For efficiency purposes, this application provides the best alternative to the regular arm
• Requires a top rail on the door of just 2-1/8" (54mm)
• Provides the best control for doors in exterior walls that swing out of a building

Low Profile, Regular Arm

• Reduced height elbow joint and straight main arm
• Allows closer to be installed where there is as little as 1" of frame face or ceiling clearance

CloserPlus® Arm

• Arm incorporates a stop at the arm's soffit plate to dead stop the door at a predetermined degree of door swing between 85° and 110°, in 5° increments
• Prior to dead stop the door closer's backcheck feature slows the door speed to reduce the impact of the stop action
• Intended for use where an auxiliary door stop cannot be used and no more than moderate abuse is anticipated

CloserPlus Ramp™ Arm

• Ramp and plunger design that easily slides into place reducing wear
• Ideal for applications where the door will constantly be pulled out of hold open

CloserPlus Spring™ Arm

• Arm incorporates a stop at the arm's soffit plate to dead stop the door at a predetermined degree of door swing between 85° and 110°, in 5° increments
