Hubbell Incorporated HPW89D Standoff Bracket 2.48in W 1.50in H telephone accessory

Telephone Standoff Bracket

The Hubbell Incorporated HPW89D is a white standoff bracket designed for structured cabling installations. It provides a secure mounting surface for 110 punchdown termination blocks, specifically the 89B type. The bracket includes mounting screws for immediate installation onto a suitable surface. It is intended for technicians and installers managing copper distribution frames.

Build Integration and Cable Management

This accessory fits into a build by creating a dedicated standoff space for termination hardware on a backboard or rack. It requires a flat mounting surface and basic tools to drive the supplied screws into place. Once installed, it frees up board space by holding the 89B block away from the surface. Integrated cable routing spools help dress distribution cables and jumper wires neatly.

Thermal Noise and Power Characteristics

As a passive metal bracket, the HPW89D draws no electrical power and generates no heat during operation. It produces zero acoustic noise because it contains no moving parts, fans, or active electronic components. The unit simply provides physical support and cable pathway management for the connected punchdown system.
