CLOSERPLUS
GENERAL INFORMATION
Application
Norton CloserPlus Door Controls offerthe middle ground
between simple friction hold-open arms available with most closers, and the sophisticated
control provided by Norton Unitrol® Door Controls. Norton CloserPlus provides the control
of a full feature door closer plus a positive door stop, with or without a manual
engage/disengage hold-open feature.
CloserPlus Door controls are available with a wide choice
of Norton Door Closers, This includes conventional-size door closers and adjustable
multi-size door closers in either ANSI size 2 thru 6 power range or A.D.A. Accessibility
Code power range (low resistance sizes 1 thru 4).
Norton CloserPlus Door Controls are ideal for high traffic
areas where a door stop is desired and where hold-open should be engaged on an elective
basis. The Norton CloserPlus is an excellent door control for schools, auditoriums,
churches and other facilities with periodic high traffic.
