Adapter Keystone double white Legrand SUNO 721145 — dual keystone insert, white

Legrand SUNO Adapter Keystone double (white) is a compact mounting insert that accepts two keystone modules and fits standard wall plates and surface boxes. Designed for modular cabling, this double keystone adapter provides a tidy termination point for network, audio/video and telecommunication jacks, allowing individual modules to be installed or replaced without altering the surrounding plate or box. The product is finished in white to match common interior fittings and support discreet installation in residential or commercial environments.

Advantages

The double keystone adapter offers a simple, tool-friendly method to mount two keystone modules in a single opening, ensuring consistent alignment and a secure snap-in fit. Its modular design reduces downtime when changing connectors and simplifies upgrades or maintenance of cabling systems. The white finish helps maintain a uniform look with standard wall plates, and the adapter’s compact form factor conserves faceplate space while accommodating two connectors side by side.

Suitable for

• Home and office network outlets for RJ45 Ethernet modules
• Audio/video wall plate installations using RCA, HDMI or coax keystone modules
• Telephony and structured cabling points requiring modular keystone jacks
• Retrofit and renovation projects where clean, replaceable connectors are needed

How to use

Insert appropriate keystone modules into the two openings until they click into place, then align the adapter with the wall plate or surface box opening and press until it snaps securely.
