Panduit PSL-DCJB-BL RJ45 Jack Block-Out Device, Black 10-Pack

Overview

The Panduit PSL-DCJB-BL is a polycarbonate RJ45 jack block-out device designed to physically secure unused network ports against unauthorized patch-ins, dust ingress, and foreign-object damage. Each pack ships with 10 black devices and one dedicated removal tool — everything needed to lock down an entire patch panel row or wall-plate run in a single step. At 0.46 in. wide and 0.4 in. tall, the PSL-DCJB-BL seats flush in standard RJ45 openings without protruding into adjacent port clearance.

For data centers, telecom rooms, and enterprise wiring closets where physical port security is a compliance or audit requirement, these block-out devices provide a fast, tool-assisted deterrent that is removable only with the included key tool — not by casual hand-pulling. Panduit's copper-systems physical security line is purpose-built for structured cabling environments where access control extends all the way to the port level.

Key Features

• Polycarbonate construction: polycarbonate resists cracking and deformation under repeated insertion cycles, so devices stay seated securely rather than loosening over time in high-traffic patch panels — relevant in co-location and hot-aisle/cold-aisle rows where ports are touched frequently.
• Fits most standard RJ45 openings: the 0.46 in. (11.6 mm) width and 0.4 in. (10.1 mm) height are sized to the RJ45 module footprint common across keystone jacks, patch panels, and modular faceplates — one SKU handles the majority of your installed base without per-vendor variants.
• Removal tool included: the pack ships with one dedicated removal tool, meaning access requires the correct instrument rather than a fingernail or improvised probe. For compliance audits requiring documented port-access control, this qualifies as a physical deterrent layer — faster and cheaper than port-disable policies enforced entirely in software.
• 10 devices per pack: a single PSL-DCJB-BL covers a half-row of a 24-port patch panel or a full quad wall plate. For larger rollouts, carton quantity is 20 units (two 10-packs), keeping bulk purchasing straightforward.
• Black color coding: black devices stand out visually against the beige or grey faceplates common in structured cabling, making it immediately apparent at a glance which ports are locked — useful during moves, adds, and changes when technicians need to spot available versus restricted ports quickly.
• Dust and debris protection: beyond security, a seated block-out device keeps RJ45 jack contacts clean in environments with elevated particulate (raised-floor data centers, manufacturing-adjacent wiring rooms, warehouse IT closets) — reducing connector oxidation and intermittent link faults that are difficult to trace.
• Low-profile form factor: at 0.51 in. overall length and 0.4 in. height, the device does not interfere with cable management fingers or adjacent port access in 1U patch panels where horizontal clearance is tight.

Integration & Compatibility

The PSL-DCJB-BL is compatible with most standard RJ45 jack module openings, including Panduit's own keystone jacks and patch panels as well as third-party modules conforming to standard RJ45 footprint dimensions. If you are standardizing on physical port security accessories across a multi-vendor structured cabling infrastructure, verify opening dimensions against the 0.46 in. width and 0.4 in. height spec before committing to large quantities — non-standard jacks with recessed or oversized openings may not retain the device reliably.

For installations requiring color-coded port management across multiple zones or access tiers, Panduit offers block-out devices in additional colors within the same product family — pairing color assignments with access-level policies (e.g., black = restricted, yellow = guest VLAN) is a common structured-cabling practice in enterprise environments. Pair with a structured cabling patch panel or modular wall plate for a complete port-security solution.

Frequently Asked Questions

Q: What jack types does the PSL-DCJB-BL fit?

A: The PSL-DCJB-BL is designed for most standard RJ45 jack module openings. It measures 0.46 in. (11.6 mm) wide and 0.4 in. (10.1 mm) tall. Verify your jack's opening dimensions before bulk ordering if you are working with non-standard or proprietary modular jacks.

Q: How many devices and tools come in one pack?

A: Each pack includes 10 black block-out devices and 1 removal tool. Carton quantity is 20 units (two packs). The removal tool is required to extract a seated device — it cannot be removed by hand.

Q: Can the PSL-DCJB-BL be removed without the tool?

A: No. The block-out device is designed to require the included removal tool for extraction. This is intentional — it provides a physical access deterrent so that unauthorized users cannot simply pull the device out by hand.

Q: What material is the PSL-DCJB-BL made from?

A: The device is constructed from polycarbonate, which provides durability and resistance to cracking under repeated insertion and removal cycles in active patch environments.

Q: Is the PSL-DCJB-BL available in other colors?

A: This listing covers the black (BL) variant. Panduit offers block-out devices in multiple colors within the same product family, which supports color-coded port access policies across different network zones or security tiers.

Q: Does this product help with physical port security compliance?

A: Yes. For frameworks that require documented physical access controls at the network port level (such as PCI-DSS physical security requirements or internal IT security policies), the PSL-DCJB-BL provides a tool-required deterrent that prevents unauthorized RJ45 patch-ins on unused jacks without relying solely on switch-level port-disable configurations.
