Panduit SRBM19BLY Strain Relief Bar with Hook & Loop Cable Ties

Overview

The Panduit SRBM19BLY is a 19-inch, 1U rack-mount strain relief bar engineered for structured cabling environments where patch panel cable management directly affects port accessibility and long-term serviceability. Built from cold-rolled steel (CRS) and finished in black, this bar ships with six Tak-Ty™ hook-and-loop cable ties pre-included — no hunting for tie-wraps when you're mid-installation. Its elevated cable tie attachment points and quick-release mounting mechanism make it a practical choice for high-density patch fields in telecom rooms, data centers, and network closets.

At 19 inches wide (482.6 mm) and 1.96 inches tall (49.8 mm), the SRBM19BLY occupies a single rack unit directly below or above the patch panel it serves, keeping cable dressing tight without consuming additional RU in already-crowded enclosures.

Key Features

• Supports up to 72 cable terminations: The elevated tie-down attachment points create enough vertical separation to bundle and route dense copper runs without crushing jacket insulation — relevant on high-pair-count Cat6A bundles where bend radius compliance is non-negotiable.
• Six Tak-Ty™ hook-and-loop ties included: Reusable hook-and-loop fasteners mean future moves, adds, and changes don't require cutting and replacing standard zip ties. On a live patch panel, that distinction matters — no snip risk near active pairs.
• Quick-release mounting mechanism: The tool-assisted quick-release feature lets you drop the bar away from the panel face without disturbing the cable bundle, which is the practical way to access patch panel ports during a high-density re-termination or troubleshooting session.
• Cold-rolled steel (CRS) construction: CRS provides the structural rigidity to support the weight of up to 72 bundled cables across a 19-inch span without bow or deflection over time — a meaningful durability point in permanent installations where the bar won't be revisited for years.
• 19-inch rack-standard width (482.6 mm): Drop-fits standard EIA-310 two-post and four-post open-frame racks as well as enclosed rack cabinets without modification. No custom drilling, no adapter plates.
• 1U height profile (49.8 mm / 1.96 in): Single-rack-unit footprint keeps the cable management overhead proportional to the patch panel it supports — you're not surrendering 2U to manage one panel's worth of horizontal runs.
• RoHS-compliant materials: Meets RoHS requirements, which matters for installations in EU-destination projects or enterprise procurement programs with environmental compliance mandates.
• Designed for use with patch panels: The geometry and attachment point spacing are optimized for horizontal cable dressing immediately behind or below a copper patch panel — not a generic bar repurposed for this application.

Integration & Compatibility

The SRBM19BLY is specified for use with patch panels in copper structured cabling systems. Panduit lists competitor cross-references 41150-019 and WM-3A for integrators migrating from other brands' strain relief hardware. The bar mounts in any standard 19-inch rack rail set and pairs naturally with Panduit's Panduit copper patch panel lineup, though the 19-inch EIA-310 standard makes it physically compatible with third-party panels as well. For rack cable management deployments, pair this bar with horizontal cable managers above and below the patch panel run to complete a dress-and-route solution. If you're planning a full structured cabling build-out, review the network cabling planning guide for patch panel density and cable management ratio recommendations. For power distribution and PDU runs in the same rack, rack-mount PDUs benefit from the same horizontal dressing discipline this bar enforces on data cabling.

Frequently Asked Questions

Q: How many cables can the SRBM19BLY manage?

A: Panduit rates the SRBM19BLY to carry and route up to 72 cables. The elevated attachment points distribute bundle weight and maintain bend radius compliance across the full 19-inch span.

Q: Does the SRBM19BLY include cable ties, or do I need to order them separately?

A: Six Tak-Ty™ hook-and-loop cable ties are included in the package. These are reusable fasteners, so no additional ties are required to get started.

Q: What rack form factor does the SRBM19BLY fit?

A: The bar is 19 inches wide (482.6 mm) and mounts in standard EIA-310 19-inch rack rails — compatible with two-post open-frame racks, four-post open-frame racks, and enclosed rack cabinets without modification.

Q: Is the SRBM19BLY RoHS compliant?

A: Yes. The SRBM19BLY meets RoHS compliance requirements, per Panduit's published standards data for this SKU.

Q: How much rack space does the SRBM19BLY consume?

A: It occupies 1U (1.96 inches / 49.8 mm in height), keeping the overhead proportional to a single patch panel directly adjacent to it.

Q: What is the SRBM19BLY made of?

A: The bar body is cold-rolled steel (CRS), finished in black. CRS construction provides the rigidity needed to support a full 72-cable bundle across the 19-inch span without deflection.

The SRBM19BLY is one of those parts that doesn't get specified early enough in a rack build — and you feel it the first time you need to repatch a dense panel without it. The quick-release mount is what makes this bar worth calling out specifically: you can drop the bar clear of the panel face to access rear-port terminations without disturbing the dressed cable bundle, which is exactly what you need in a live environment where pulling a cable tie means re-dressing 72 runs.

Technical Highlights:

• 72-cable capacity: Elevated tie-down points keep bundle geometry intact at full load across the 19-inch span — at high cable counts, a bar without vertical clearance just flattens the bundle against the panel and defeats the purpose.
• Six Tak-Ty hook-and-loop ties included: Hook-and-loop is the right fastener choice for a patch environment. A zip tie you have to cut is a liability in a high-change-rate MDF or IDF; these reusable ties eliminate that risk entirely.
• CRS construction, 1U profile: Cold-rolled steel at 49.8 mm tall holds its shape under load and doesn't flex when the bundle weight shifts — relevant on 24-port panels where all ports are populated with Cat6A, which runs heavier per-foot than Cat5e or Cat6.

Deployment Considerations:

• Mount the SRBM19BLY directly below the patch panel it serves — cable drop from panel ports to the tie-down points should be as short as possible to keep the dress clean and prevent excess slack from migrating toward adjacent patch panels.
• Watch the 1U clearance above and below: in fully populated 42U racks, a 1U strain relief bar for each 1U patch panel doubles your cable management RU consumption — plan rack layout with this ratio in mind before you start ordering panels.

The SRBM19BLY is the right call for any copper patch panel row in a telecom room or IDF closet where structured cabling density is high enough to make re-patching a regular event — enterprise campuses, co-location installations, and high-density security system head-end racks where camera feeds terminate on patch panels before hitting the NVR or switch fabric.
