Rack frame Rittal 3286.700 — metallic rack accessory for server and network enclosures

The Rittal 3286.700 rack frame is a metallic accessory engineered to mount and reinforce server and network enclosures. With a metallic finish and a listed weight of 6.2 kg, this frame provides a stable mounting interface for cooling units, equipment rails and other enclosure-mounted components. The design enables quick installation and removal of compatible roof-mounted cooling units using a two-part quick-change frame: the lower section is screw-fastened to the enclosure together with a seal, while the upper section remains attached to the cooling unit and is engaged or released with quick-release fasteners.

Advantages

The quick-change concept reduces servicing time by allowing the cooling unit to be detached and reattached rapidly without disturbing the sealed lower frame. An integrated drainage trough protects the interior of the enclosure from oil ingress in oily atmospheres, improving equipment reliability. The metallic construction delivers mechanical reinforcement for cabinets and racks and supports additional accessories such as equipment rails or auxiliary fans.

Suitable for

• Data center server cabinets that require roof-mounted cooling units or reinforced mounting points
• Telecommunications cabinets in exchanges and base station sites
• Industrial racks where protection against oily contaminant ingress is needed
• Applications where reduced maintenance downtime for cooling units is important

When it may not be suitable

This rack frame is designed specifically for enclosures that accept a quick-change roof-mounted cooling arrangement. It may not be compatible with enclosures that use non-standard roof geometries or proprietary mounting systems. For applications where corrosion resistance beyond a standard metallic finish is required (for example, highly corrosive outdoor environments), an alternative surface treatment or a different material may be preferable.

Key specifications

• Material: metallic frame construction
• Weight: approximately 6.2 kg
• Finish: metallic surface
• Design: two-part quick-change frame with lower screw-fastened section and upper quick-release section
• Feature: integrated drainage trough to protect against oil ingress
• Primary use: mounting and reinforcement for roof-mounted cooling units and enclosure accessories

How to use

Secure the lower section of the rack frame to the enclosure roof using the provided screw points and ensure the seal is correctly positioned to maintain enclosure integrity. Mount the upper section to the cooling unit with the quick-release fasteners. To install the cooling unit, engage the upper section with the fixed lower frame until the quick-release fasteners lock; to remove the cooling unit, release the quick-release fasteners and lift the unit away while the lower frame and seal remain in place. Confirm the drainage trough is unobstructed and perform routine inspections of fasteners and sealing elements during maintenance.

What to consider before purchase

• Verify physical compatibility with your enclosure roof geometry and mounting hole pattern
• Confirm that the cooling unit intended for use supports the quick-change upper-frame mounting method
• Assess environmental conditions to determine if the standard metallic finish provides sufficient corrosion resistance
• Ensure load-bearing capacity meets the weight of installed cooling units and accessories

Usage recommendations

Install the lower frame and seal as a permanent part of the enclosure roof to allow quick, safe exchange of cooling units; regularly check the drainage trough and seals for contamination to maintain protection against oil ingress and to extend service life.
