Ives 5BB1 5-Knuckle Ball Bearing Hinge, Standard Weight - 4.5" x 4.5" with Electrification Options
Gemini said
The Ives 5BB1 4.5" x 4.5" is an industry-standard, commercial-grade ball bearing hinge designed for medium-weight doors or doors requiring low-frequency service. When specified with Electrification Options, it becomes a critical component of an access control system, allowing power to be transferred from the frame to the door for hardware like electric strikes, exit devices, or electrified locks.
Product Specifications
-
Model: 5BB1 (5-Knuckle, Ball Bearing)
-
Size: 4.5" x 4.5" (The standard size for 1-3/4" thick commercial doors)
-

Electrification Options
When used in security applications, the 5BB1 can be modified with several power-transfer technologies:
-
EPT (Electric Power Transfer) Prep: The hinge is prepared to work in conjunction with a separate power transfer unit.
-
TWP (Through-Wire): The hinge barrel is modified to allow low-voltage wires to pass through.
-
TW4: 4-wire configuration.
-
TW8: 8-wire configuration.
-
TW12: 12-wire configuration.
-
-
CON (Allegion Connect): Features a "plug-and-play" Molex-style connector. This eliminates the need for wire nutting and reduces installation time and errors when connecting to other Allegion electrified hardware (like Von Duprin exit devices or Schlage locks).
-
MON (Monitor Switch): Includes an internal switch that signals whether the door is open or closed to a security console.
