Vector 4.5" Ball Bearing NRP ETW4 Hinge

4-1/2" x 4-1/2" | Ball Bearing | Non-Removable Pin | ETW4 4-Wire Power Transfer | US32D, US26D or US10B

Combine smooth commercial door operation, enhanced security, and concealed electrical power transfer with the Vector Hinge Co. 4-1/2" x 4-1/2" Ball Bearing NRP ETW4 Hinge.

Designed for electrified commercial openings, this hinge features an integrated ETW4 four-conductor through-wire system that transfers power and control wiring from the frame into the door without an exposed surface-mounted door loop.

The Non-Removable Pin (NRP) provides added security for outswinging and secured openings, while the ball-bearing construction helps reduce friction and wear in high-traffic commercial applications.

ETW4 Concealed Power Transfer

The integrated ETW4 system provides four conductors through the hinge, creating a concealed electrical pathway between the door frame and electrified hardware installed in the door.

Typical applications include:

• Electrified Locksets

• Electrified Exit Devices

• Request-to-Exit Hardware

• Door Monitoring

• Access-Control Hardware

• Other Compatible Low-Voltage Door Equipment

Because the wiring passes directly through the hinge, the installation maintains a clean appearance without an exposed armored door loop.

Non-Removable Pin – NRP

The NRP feature helps prevent removal of the hinge pin while the door is closed.

This is particularly useful for:

• Exterior outswinging doors

• Secure entrances

• Controlled-access openings

• Commercial service doors

• Institutional facilities

Ball-Bearing Construction

Ball bearings reduce friction between the hinge knuckles, helping provide:

• Smooth door movement

• Reduced hinge wear

• Quiet operation

• Improved performance on frequently used doors

• Longer service life compared with basic plain-bearing hinges
