Keystone Triple CAT6A Outlet Module Synergy21 S216327/S216380, Keystone Short with Cable Clamp, Pure White

The Keystone Triple CAT6A Outlet Module Synergy21 S216327/S216380, Keystone Short with Cable Clamp, Pure White provides three RJ45 keystone ports in a compact short-depth housing designed for installation in standard flush boxes and compatible faceplates. Engineered for CAT6A cabling, the module offers shielded or unshielded network connectivity depending on the jacks used, and the integrated cable clamp provides strain relief to maintain reliable terminations and reduce mechanical stress on cable pairs. The pure white finish matches common office and residential wiring accessories for a discreet, low-profile installation.

Advantages

The triple keystone format consolidates three data/voice outlets into a single module, saving faceplate space and simplifying wiring runs. The short-depth design makes the module suitable for shallow flush boxes and backbox-constrained installations while still supporting CAT6A performance. The built-in cable clamp secures the incoming cable, reducing the risk of pair movement after termination and improving long-term connection stability. The neutral pure white color is widely compatible with standard wall plates and interior décors.

Suitable for

• Office workstations requiring multiple Ethernet ports in one faceplate position
• Residential home network outlets where several RJ45 connections are needed (e.g., router, VoIP, media)
• Patch panels or structured cabling endpoints that use keystone-compatible faceplates
• Installations with limited backbox depth where a short keystone module is necessary

When it may not be suitable

This keystone module is intended for use with CAT6A-rated cabling and compatible keystone jacks; it is not a complete cable termination solution by itself and requires appropriate RJ45 keystone inserts and a matching faceplate. For environments that demand integrated shielding across the faceplate or specialized industrial connectors, additional components or different module types may be required. Very high-density installations that require more than three ports per opening may be better served by multi-port panels or larger faceplates.

Key specifications

• Port count: 3 RJ45 keystone ports
• Compatibility: Designed for CAT6A cabling and keystone-format jacks
• Form factor: Short-depth keystone module for flush box installations
• Cable strain relief: Integrated cable clamp for secure termination
• Finish: Pure white
• Mounting: Fits standard keystone faceplates and flush wall boxes

How to use

Install the module by inserting it into a compatible keystone faceplate or directly into a flush wall box, ensuring the short-depth orientation matches the available backbox space. Terminate each CAT6A cable pair to the chosen RJ45 keystone jacks following the jack manufacturer’s wiring color code and punch-down or IDC instructions. Use the integrated cable clamp to secure the cable jacket before finalizing terminations to reduce strain on the connectors. Once jacks are inserted and secured, attach the faceplate to the wall box and verify network connectivity with appropriate test equipment.

What to consider before purchase

• Ensure compatibility of the keystone jacks you plan to install with CAT6A performance requirements
• Confirm faceplate and flush box dimensions to accommodate a short-depth module
• Decide whether shielded jacks or additional grounding are required for your environment
• Plan for cable routing to make effective use of the integrated cable clamp and maintain bend radius

Usage recommendations

For consistent CAT6A performance, use certified CAT6A keystone jacks installed according to manufacturer termination procedures, secure the cable with the clamp to prevent movement, and test each port with a suitable network tester after installation to validate wiring and performance.
