Hubbell Premise Wiring SF35GFFOW 3.5mm Keystone Coupler

Product Description

The HUBBELL PREMISE WIRING SF35GFFOW is a snap-fit keystone coupler designed to join two 3.5mm audio connections in a female-to-female configuration. This low-profile insert snaps directly into standard keystone wall plates, patch panels, and surface-mount boxes without tools, providing a clean in-wall or structured-wiring termination point for 3.5mm audio circuits. Electricians and low-voltage technicians use this fitting when routing audio signals through permanent panel or plate installations. The snap-fit retention mechanism locks the coupler securely in place once seated, maintaining a reliable connection point in both residential and light commercial environments.

This keystone coupler is suited for structured wiring installations where 3.5mm audio lines need a fixed, panel-mounted pass-through point. Typical applications include conference rooms, classrooms, home theater systems, and any installation where a permanent 3.5mm audio jack location is needed at a wall plate or patch panel. It accepts standard 3.5mm plugs on both faces, allowing a cable run from a source device on one side to a destination device on the other without exposed inline adapters.

Key Features

• Snap-fit design seats into any standard keystone opening without tools or adhesives
• Female-to-female 3.5mm configuration provides a clean pass-through at wall plates or patch panels
• Compatible with keystone wall plates, patch panels, and surface-mount enclosures
• Sold individually, allowing flexible quantity purchasing for multi-port installations
• Low-profile keystone form factor keeps finished plate appearance consistent with other keystone inserts

Compatibility

Designed as an OEM-style snap-fit insert for standard keystone wall plates, patch panels, and surface-mount boxes accepting keystone modules.

Installation Notes

Installation is performed by low-voltage technicians or electricians rough-finishing structured wiring systems. No tools are required to seat the coupler into a keystone opening — press firmly until the retention tabs click into place. Verify the host plate or panel opening conforms to standard keystone module dimensions before installation. De-energize any adjacent powered outlets or low-voltage wiring in the same enclosure before handling nearby terminations per applicable NEC low-voltage wiring practices.
