Middle Atlantic SR28-IVCMF-40 Internal Vertical Finger Cable Manager, 40 RU
Overview
The Middle Atlantic SR28-IVCMF-40 is an internal vertical finger cable manager designed specifically for SR28-series racks at 40 rack units of capacity. If you're running structured cabling inside a deep rack — security NVRs, PoE switches, patch panels, UPS units — cable discipline is the difference between a maintainable system and a spaghetti pull that costs hours every service call. This manager routes and retains cables vertically along the interior of the rack, keeping horizontal run lanes clear and making individual cable traces possible without disturbing adjacent gear. The SR28-IVCMF-40 (often searched as SR28 IVCMF 40) ships at 5 lbs, which is consistent with a full-height finger assembly built to handle real cable loads rather than token dress clips.
Key Features
- 40 RU Internal Vertical Run Capacity: spans the full usable height of a 40 RU SR28 enclosure, so every panel, switch, and recorder in the rack has a dedicated vertical path to route to — no mid-rack dead zones where cables bunch and pull on ports.
- SR28 Series-Specific Fit: designed for the SR28 rack family, meaning the mounting geometry, finger depth, and spacing align to Middle Atlantic's own interior dimensions. Drop-in installation without cutting, shimming, or improvising brackets.
- ETL Listed: independently verified to applicable safety standards. For commercial integrations and enterprise deployments where the AHJ or facility team requires listed components, this clears that box without extra documentation requests.
- 5 lb Shipping Weight: the assembly is light enough for a single installer to handle and position during rack buildout, no staging lift required — practical when you're commissioning racks in an IDF closet or equipment room with limited swing space.
Integration & Compatibility
The SR28-IVCMF-40 is engineered for Middle Atlantic SR28-series racks and should be confirmed against your specific SR28 enclosure model before ordering. If you're building out a complete rack infrastructure for a security or AV installation, pairing this cable manager with proper patch panel organization and a rack power distribution unit gives you a fully serviceable equipment bay. Consult Middle Atlantic's cable management lineup for horizontal managers and lacing bars that complement this vertical assembly.
Frequently Asked Questions
Q: What rack series is the SR28-IVCMF-40 compatible with?
A: The SR28-IVCMF-40 is designed for Middle Atlantic's SR28 rack series. Confirm compatibility with your specific SR28 enclosure model before ordering.
Q: How tall is the SR28-IVCMF-40?
A: It is rated for 40 rack units (40 RU), covering the full interior height of a 40 RU SR28-series enclosure.
Q: Is the SR28-IVCMF-40 ETL listed?
A: Yes, the SR28-IVCMF-40 carries an ETL listing, confirming it has been independently tested to applicable safety standards.
Q: What does the SR28-IVCMF-40 weigh?
A: The shipping weight is 5 lbs (2.3 kg).
Q: Can the SR28-IVCMF-40 be used with non-Middle Atlantic racks?
A: This manager is designed specifically for the SR28 rack family. Fit and mounting geometry are SR28-specific; it is not intended as a universal rack accessory.
The SR28-IVCMF-40 is a purpose-built internal vertical finger manager for the SR28 rack family at 40 RU — and that specificity matters. At 5 lbs for a full 40 RU span, the assembly is substantial enough to handle realistic cable bundles without flexing, but light enough that one person can stage and mount it during rack buildout before gear goes in.
Technical Highlights:
- 40 RU Coverage: a single assembly covers the complete interior height of a 40 RU SR28 enclosure — no stacking shorter managers or dealing with coverage gaps mid-rack where cables tend to migrate.
- ETL Listing: independently tested to applicable safety standards, which matters on commercial and government installations where the facility or AHJ requires listed rack components — saves the back-and-forth with compliance documentation.
- SR28-Specific Geometry: designed to the SR28 interior dimensions, so you get consistent finger depth and spacing without shimming or field-modifying the manager to fit — install time is measured in minutes, not hours.
Deployment Considerations:
- Install the SR28-IVCMF-40 before populating the rack — routing cables after gear is installed significantly increases labor and risks stress on ports. Stage the manager first, dress cables as each device is mounted.
- This manager is SR28-specific. If your enclosure model is outside the SR28 family, verify before ordering — Middle Atlantic's rack lineup includes multiple series and a mismatch means the mounting geometry will not align.
The SR28-IVCMF-40 is the right call for security operations centers, IDF closets, and equipment rooms where an SR28 rack is already specified and cable serviceability needs to survive repeated adds and changes over a multi-year deployment lifecycle.
