Adjustable Stroke
Provides variable reduction of the retract stroke
and serves as a positive stop for the cylinder
piston. Consists of a threaded stud located in

on the end of the adjustment stud allow for
simple yet precise positioning to accommodate
varying retract stroke requirements.
TO ORDER: Enter option code A(_).
Specify adjustable stroke length.
Adjustable Stroke with Piston
Provides variable reduction of the retract
stroke and serves as a positive stop for the
cylinder piston. Consists of an adjustable stop
piston attached to a threaded stud located in
the cap end of the cylinder. Milled wrench flats
on the end of the adjustment stud allow for
simple yet precise positioning of the stop
piston to accommodate varying retract stroke requirements.
TO ORDER: Enter option code AA(_). Specify adjustable stroke length.
Cushion Adjust Screw
Optional Locations
Option code N(– –)
