The Yale Grade 1 Door closers 3000 Series architectural door closers offer the perfect combination of reliability, appearance, and durability in today's market. With features such as staked valves, self-drilling, and tapping screws, rack and pinion design, precise valve adjustment, and a complete range of arm and cover options, the Yale 3000 can meet virtually any application challenge. Two popular Yale closers are the 3301 and 3501. Both are excellent for different applications.
Yale Locks 3301 Closer
Regular Arm
This is the only pull side application where a double lever arm is used. It is the most power-efficient application for a door closer. Sufficient frame, door and/or ceiling clearance must be considered.
Top Jamb
For efficiency reasons, this application provides the best alternative to the regular arm application. There must be sufficient frame face and/or ceiling clearance for this application. It requires a top rail on the door of just 2-1/4"
(57mm). This application provides the best door control for doors in exterior walls that swing out of a building.
Parallel Arm
This application provides the most appealing design appearance for a surface-mounted door closer having a double lever arm. This also makes it beneficial in vandalism-prone areas. It is on the push side of the door and the arm assembly extends almost parallel to the door. In the closed position, there is very little or no hardware projecting beyond the frame face in most situations.
Yale Locks 3501 Closer
Regular Arm
Since the arm assembly projects directly out from the
frame, this application may present an aesthetics issue or
be prone to vandalism.
Jamb Arm
The entire door closer and arm assembly project from
the frame, similar to the regular arm application, where
matters of appearance and malicious abuse can be of
concern. Consideration must be given to depth of reveal.
Parallel Arm
Due to the geometry of the arm, it is approximately 25% less power-efficient than a regular arm application. The entire closer and arm assembly are mounted below the frame stop. Top rail clearance dimensions will vary based on the type of cover used.
