4U 100MM Swing Frame Collar

The 4U 100MM Swing Frame Collar is a networking accessory for cabinets and racks. It is part of the Networking range and sits in the Cabinets & Racks category, making it a practical choice for IT professionals and installers who work with rack-based infrastructure.
Racks are the backbone of many server rooms, comms cupboards and network closets. Accessories such as collars and frame components help keep equipment aligned, supported and easy to manage. This collar is described for use within a 4U space and is specified at 100 mm, which are the two key figures to confirm against your installation.

Typical uses
The collar is intended for installers who need to complete or adapt a 4U rack arrangement. Typical uses include supporting equipment in a swing frame cabinet, tidying a networking rack layout, and preparing space for switches, servers or patch panels that occupy four rack units.
Choosing the right fit
Because rack accessories must match the frame and equipment they are used with, it is worth checking the supplied dimensions against your rack specification before ordering. Confirm the mounting arrangement, the available rack space and any other equipment already installed. This helps avoid compatibility issues and ensures a clean, secure installation.
Why choose this accessory
Good rack management improves airflow, simplifies maintenance and makes future changes easier. A dedicated 4U collar gives you a defined, standard-height solution that fits well into organised networking environments, from small office comms rooms to larger data installations.
Installation considerations
Plan your rack layout before fitting the collar. Measure the available space, note the position of existing equipment, and keep cable routes clear. Handle the component carefully during installation and follow the guidance supplied with your rack system.
