Offset Spindles Center Hung Offset Extended Spindle Insert
NOTE: Closer and arm must be installed per template for
door clearances shown to be valid.

Closers with extended spindle inserts are used with thresholds, carpeted floors, or terrazzo pans or in cases where
more clearance between door and floor is required. All spindles are zinc plated.
Spindles are available with a 3° offset for additional pressure to hold door in the closed position. Normally, this is only necessary for center-pivoted single acting
applications. However, they can also be used with other applications to compensate
for templating errors. Specify hand of offset spindle when ordering.
Cover Plate
Universal cover plate 7510, suitable for left hand/right hand, 3/4" offset, 1-1/2" offset and center pivoted doors. Material is stainless steel or brass depending on the plated finish specified.
