Yale UNI3501 Door Closer with Full Cover and UNI Stop Arm | Yale 3000 Series Door Closer, Grade 1

UNI STOP ARM

Can be used for either parallel arm or top jamb applications. UNI Stop arms combine the features of a double lever arm overhead door stop/holder with the backcheck feature of the door closer to reduce door stopping shock loads to a minimum. This arm uses a compression spring buffer at the soffit plate/arm shoe that absorbs 30 lbf. of force, 5° prior to the door’s dead stop. The UNI Stop arm, coupled with the door closer's backcheck feature, proves the most controlled stop available with a surface door closer. For parallel arm applications there are three different length arm assemblies. Each length is designed for a specific range of door widths, to provide precise door control. This further lessens the dead stop impact on the door’s hinges/ pivots.

DELAYED ACTION

Adjustable Delayed Action Closing

An optional hydraulic feature that adds a third speed range to the closing cycle. This feature becomes effective when the door is opened and released at any point beyond 70°. The amount of time delay depends upon the combination of the angle of door release and valve adjustment. The valve can be adjusted with a 1/8" (3mm) hex key from no delay time up to maximum delay times of:
