Pass-Through RJ45 Modular Plugs for Cat6/6a UTP - Red Tint, 100 pcs

In this review the Simply45 S45-1700P is evaluated as a bulk solution for technicians and installers who need reliable pass-through RJ45 modular plugs for unshielded Cat6 and Cat6a UTP cables. The bottom line: it is a straightforward, commercial-rated connector pack that saves time on terminations and improves identification on dense jobsites thanks to its light red tint and integrated Cap45 safety cap. For anyone terminating 23AWG solid LAN cable at scale, the plug design and gold-plated 3-prong pins make it a sensible choice.

Key Features

• Single-piece pass-through: The single-piece construction eliminates the need for a separate load bar, simplifying terminations and reducing parts to manage on site.
• 24ct gold-plated 3-prong pins: The three-prong contact design improves contact reliability over common 2-prong designs, helping maintain signal integrity for Cat6/6a runs.
• Color-tinted identification: The light red tint makes it quick to identify these plugs among other colors during batch terminations or labeling workflows.
• Cap45 safety cap: Each plug uses the Cap45 cap to fully cover exposed conductor ends, removing electrical risk from pass-through wires and fitting standard RJ45 sockets.
• Commercial rating: With UL94 V0 (IEC 60695-11-10) rating, these plugs are suitable for CMP Plenum, CMR, CM and LSZH up to B2ca-rated cables in commercial installs.

Who It's For

The S45-1700P is aimed at network installers, data center technicians and contractors who terminate large quantities of Cat6 or Cat6a unshielded (UTP) solid 23AWG cable and want a time-saving pass-through option. It is particularly useful where cable identification and safety are priorities, such as multi-cable installations or plenum spaces that require commercial-rated components.

It is less appropriate for shielded cable (STP/FTP) or very thin stranded patch cables, since the plugs are specified for 23AWG solid conductors and unshielded cable. Hobbyist users who only terminate occasional patch cables may prefer a smaller pack or a plug designed for stranded conductors.

Pros & Cons

Pros

• Single-piece pass-through design speeds up terminations and reduces fiddly parts.
• 24ct gold-plated 3-prong pins provide reliable contact and better durability than many 2-prong alternatives.
• Color-tinted plugs make visual sorting and inventory control faster on crowded jobsites.
• Cap45 design removes exposed conductor risk and fits standard RJ45 sockets for safe installations.

Cons

• Designed for 23AWG solid UTP only, so it is not suitable for shielded or stranded cable applications.
