Middle Atlantic PET-K-D/EWR Protective Earth Terminal Kit for EWR and DWR Wall Mount Racks

The Middle Atlantic PET-K-D/EWR is a purpose-built protective earth terminal kit designed to properly ground conductive surfaces on Middle Atlantic EWR and DWR Series wall mount racks. At a compact 9.5" x 7.0" x 0.5" and weighing just 0.1 lbs, this kit ships ready to install — no hunting for compatible hardware, no improvised grounding solutions that may not satisfy inspection. If you're commissioning a wall-mounted rack installation in a commercial or enterprise environment where bonding to earth is required by code or site standards, the PET-K-D/EWR is the factory-matched answer for the EWR and DWR Series.

Key Features

• Purpose-Matched Grounding: Engineered specifically for the EWR and DWR Series Wall Mount Rack families — not a universal adapter. That specificity matters on inspected installations where "close enough" hardware can trigger a rework. The PET-K-D/EWR integrates without modification, preserving the rack's mechanical and electrical integrity as designed.
• Protective Earth Terminal Function: Grounds conductive rack surfaces to protective earth, which is a code requirement in many commercial and industrial deployments. Proper bonding reduces risk of electric shock from chassis faults and suppresses noise that can degrade sensitive network switching and security equipment housed in the rack.
• Compact, Low-Profile Form Factor: At 9.5" x 7.0" x 0.5" and 0.1 lbs, the kit doesn't add meaningful depth or weight to the rack assembly — relevant in wall-mount scenarios where wall clearance and load rating are already constrained.
• Part of the PET-K Series: The PET-K-D/EWR (sometimes searched as PET K D/EWR) belongs to Middle Atlantic's PET-K Series of protective earth terminal kits, meaning replacement hardware and documentation follow a consistent family structure across Middle Atlantic rack product lines.
• Eliminates Field Improvisation: Sourcing generic grounding terminals and adapting them to EWR/DWR mounting geometry wastes commissioning time and risks a non-conforming result. This kit is the correct part — install it and move on.
• Wall and Rack Mount Compatibility: Designed for wall mount rack deployments, which aligns with the EWR and DWR Series' primary installation context — server rooms, telecom closets, security head-end enclosures, and structured wiring installations where rack space is limited and racks mount directly to the wall.

Integration and Compatibility

The PET-K-D/EWR is compatible exclusively with the DWR and EWR Series Wall Mount Racks from Middle Atlantic. If your installation uses a different Middle Atlantic rack series — such as a freestanding or two-post open-frame configuration — verify the correct PET-K variant for that series before ordering. Mixing PET-K kits across incompatible rack families can result in misfit hardware and an unbonded chassis.

For integrators building out complete rack-based physical security infrastructure — NVRs, PoE switches, access control panels, video management appliances — a properly grounded wall mount rack is a baseline requirement, not an afterthought. The PET-K-D/EWR closes that loop for EWR and DWR Series deployments without requiring field engineering time.

If you're specifying a full wall-mount rack system, review the rack accessories catalog to pair the PET-K-D/EWR with appropriate cable management, blanking panels, and mounting hardware for a complete, inspection-ready enclosure build.

Frequently Asked Questions

Q: Which rack series is the PET-K-D/EWR compatible with?

A: The PET-K-D/EWR is designed specifically for Middle Atlantic DWR and EWR Series Wall Mount Racks. It is not a universal grounding kit — verify your rack series before ordering.

Q: What does the PET-K-D/EWR actually do?

A: It provides a protective earth terminal for grounding the conductive surfaces of EWR and DWR Series wall mount racks. Proper rack grounding is required by electrical codes in most commercial installations and reduces shock risk and electrical noise.

Q: What are the dimensions and weight of the PET-K-D/EWR?

A: The kit measures 9.5 inches x 7.0 inches x 0.5 inches and weighs 0.1 lbs — minimal footprint that won't affect rack depth or wall clearance calculations.

Q: Can I use the PET-K-D/EWR on a freestanding or open-frame Middle Atlantic rack?

A: No — this kit is rated for DWR and EWR Series Wall Mount Racks specifically. Middle Atlantic offers other PET-K Series variants for different rack families. Confirm compatibility against your rack model before purchasing.

Q: Is any modification required to install the PET-K-D/EWR?

A: The kit is factory-matched to the EWR and DWR Series and installs without modification. It is the OEM-specified grounding solution for those rack families.

James Everett

The PET-K-D/EWR is one of those parts that experienced integrators order at the same time as the rack itself — not as an afterthought during final punch-out when the inspector is already on-site. At 0.1 lbs and 9.5" x 7.0" x 0.5", it adds nothing to your rack's footprint or load, but it closes the grounding loop that commercial electrical codes require for metal enclosures in occupied buildings.

Technical Highlights:

• Series Specificity: This kit is factory-matched to the DWR and EWR Series Wall Mount Racks — not adapted, not modified. On inspected security head-end installs, that specificity matters more than it might seem at spec time.
• Form Factor: At 0.5" depth, the PET-K-D/EWR installs flat and doesn't encroach on wall clearance — relevant in tight telecom closet builds where every inch of standoff depth is accounted for.
• PET-K Series Lineage: Part of Middle Atlantic's PET-K Series means documentation, torque specs, and replacement sourcing follow a consistent family structure across their rack line — useful when you're managing a multi-site deployment with standardized rack configs.

Deployment Considerations:

• Confirm your rack model is DWR or EWR Series before ordering — Middle Atlantic makes multiple wall mount and freestanding rack lines, each with its own PET-K variant. A wrong-series kit won't mount correctly.
• Order this at the same time as the rack. Tracking down a single grounding kit after the rack is already installed and cabled is a disproportionate nuisance relative to its $0.1 lb footprint.

The PET-K-D/EWR is the right call for any EWR or DWR Series wall mount rack installation in a commercial security or IT environment where bonding to protective earth is part of the commissioning checklist — enterprise telecom rooms, access control head-ends, and multi-camera NVR enclosures where rack integrity is non-negotiable.
