INTRODUCTION / SPECIFICATIONS
Introduction
Yale's high security closers are designed for use in
prisons, correctional facilities, government buildings, schools, financial institutions,
or any installation where vandalism, abuse, escape, personal injury, or damage to doors,
walls, and hardware are major concerns.
The Yale Series SSCR/SCP-400/4400 Security Closers offer
the ultimate in extra heavy duty security. They feature Yale's top-of-the line heavy duty
400/4000 Series door closers with a variety of rigid arm options for regular arm and
parallel arm installation including Holder-Stop with hold-open. Fixed-link arm assemblies
are utilized on all mounts. Joints are permanent. Orbital riveted elbows and arm
shoe/soffit plate joints prevent disassembly.
Only the extruded heavy duty metal cover is handed. The arm
attaches to the frame with TORX screws, and a 4 -point security TORX fastening system
resists tampering with the cover and closer body. These closer series are especially
useful in high security correctional facilities.
Yale's 3000 Series Door Closers are offered with the same
arm options as the 400/4400 Series, but without the security cover. TORX screws are
provided as standard for tamper resistance. These closers are utilized in school and
industrial environments where heavy abuse and vandalism may occur.
The Yale Series 4500 Overhead Concealed Closer is installed
in the header of hollow metal, aluminum, or wood frames. It is highly tamper resistant and
completely concealed when the door is closed. The Series 4500DPS version features a door
position switch which is designed to communicate a "door open'' and/or ''door
closed'' situation to remote locations. 1/4'' movement of the door causes a lever arm to
actuate a switch. Movement may be adjusted. The cover plate attaches with TORX
screws. The closer is especially useful in detention facilities, warehouses, or other
controlled access environments. It may also be used to activate security cameras and
alarms.
