Spindle Extensions
Spindle extensions are available in lengths from 1/2"
to 2" increments to lengthen the spindle to meet different frame requirements. The
spindle extension fits over the closer spindle and attaches with an alien keyed screw. To
use a spindle extension the closer must be factory modified to accept the spindle
extension.
Finishes
The 4900 concealed closer cover plates are available in
both painted and plated finishes. If the arm is exposed it will be painted to either match
or complement the painted or plated cover plate.
To order, specify the finish of the cover plate. The arm
will be painted to either match or complement finish specified.
