Cisco Compatible 4PT-KIT-T2
4 Point Type 1 rack mount kit 3650/3850/9300 Series
Product Highlights
Deploying Catalyst switches in four-post racks without proper rear support risks chassis sag, poor airflow, and potential equipment damage. The 4PT-KIT-T2 is a Cisco compatible 4-point rack mount kit engineered to solve exactly that problem for your Catalyst 3650, 3850, and 9300 series switches.
This kit includes extension rails and mounting brackets that attach to the rear of the switch chassis and extend to the rear rack posts, providing secure four-point support in standard 19-inch equipment racks. The sliding rear brackets accommodate varying rack depths, making the kit versatile across different cabinet and open-frame rack configurations.
Whether you're building out a new campus access-layer closet, refreshing an existing data center rack, or meeting NEBS installation requirements, the 4PT-KIT-T2 delivers the structural integrity your deployment demands. As a Cisco compatible replacement, it provides OEM-equivalent fit and function — giving IT teams a cost-effective alternative without sacrificing quality or reliability. Ideal for network engineers and procurement teams looking to standardize four-post mounting across Catalyst switch deployments.
Features & Benefits
Four-Point Rack Stability
The 4PT-KIT-T2 secures your switch at all four rack posts — front and rear — distributing weight evenly and eliminating the chassis flex that can occur with front-only (two-post) mounting. This is especially critical in environments subject to vibration or seismic requirements.
Adjustable Sliding Rails
The rear-mount brackets feature a sliding rail design that accommodates varying rack depths. This flexibility means you can deploy the kit across different rack and cabinet models without worrying about incompatible post-to-post distances.
Broad Catalyst Series Compatibility
Designed to fit the Cisco Catalyst 3650, 3850, and 9300 series switch chassis. A single kit SKU covers multiple switch generations, simplifying procurement and reducing spare-parts inventory for teams managing mixed-generation environments.
Cost-Effective Cisco Compatible Design
As a Cisco compatible third-party replacement, the 4PT-KIT-T2 delivers the same form factor and mounting-hole alignment as the OEM kit at a more accessible price point — helping IT budgets stretch further without compromising on fit or durability.
Deployment Scenarios
Enterprise Campus IDF / Access-Layer Closets
When deploying Catalyst 9300 or 3850 switches in four-post relay racks inside intermediate distribution frames (IDFs), the 4PT-KIT-T2 provides the rear support needed to keep switches secure and properly ventilated in space-constrained wiring closets.
Data Center Top-of-Rack Deployments
In data center cabinets where equipment density and vibration are concerns, four-point mounting ensures the switch chassis remains stable and properly aligned, protecting both the switch and connected cabling over time.
NEBS-Compliant or Seismic-Zone Installations
Facilities that must meet NEBS or seismic bracing requirements typically mandate four-point rack mounting. The 4PT-KIT-T2 satisfies this requirement for supported Catalyst switch models, helping you pass compliance audits.
