Selective Hold-Open (SHO)
Factory-installed on 27 & 28 Series closers. Hold-open may be turned on/off.
Automatic Hold-Open (AHO)
Available on certain series closers with or without dead stop. Preset at factory for specific degree of hold-open. Degree of hold-open cannot be changed, nor can closer be made into non hold-open.
Delayed Action (DA) Provided on barrier-free installations. Permits door to remain ajar (at 70°) for up to 30 seconds. Operates by separate valve and can be shut off if not needed.
Not available on closers furnished with cold weather fluid, and not recommended for exterior applications because of weather factors. (27 & 28 series only)
Physically Handicapped (PH)
To comply with guidelines established in the American With Disabilities Act, lighter opening forces are met if closers are ordered with a PH prefix. If 5 pounds of opening on interior doors is needed, simply order PH. If 8.5# of force is needed, specify Prefix PH and suffix 8.5#. Be advised that lower opening forces mean lower closer forces. PH products should not be ordered for exterior doors or fire rated openings. Fire/Lifesafety openings take precedence over the convenience of ADA. Securing a building is also a major concern and a lighter closer may not be strong enough to secure a latch bolt in a strike. Use care when specifying PH products.
Cold Weather Fluid (CWF)
Should be considered in installations where ground temperature is constantly below +15°F.May be used in temperatures as low as -35°F.
Sealed Closer (SC)
Used where water contact may occur. Provides gasketing and a cover plate that are epoxied around the case with the closer inside.Not available for replacement closers unless cement case is also replaced.
(F) Used on labeled fire door requiring steel base pivot. PH with 3 pounds of opening force may not be used on fire doors.
