4U 100MM Swing Frame Collar

4U 100MM Swing Frame Collar for Cabinets and Racks

The 4U 100MM Swing Frame Collar is a rack accessory from the Networking range, grouped under Cabinets & Racks. It is designed to help you make the most of your rack-mounted equipment setup, keeping your networking hardware organised within a 4U rack space.

The product name points to a 4U height, which is four rack units, and a 100 mm dimension. Rack units are the standard vertical measure used for mounting servers, switches, patch panels and other rack equipment. Because the collar is listed as a swing frame accessory, it is intended for use with swing frame style racks or enclosures.

Network installers and IT teams often need neat, well-managed rack spaces where cables and devices can be installed and maintained without clutter. A collar of this type suits anyone building or extending a networking rack who wants a dependable accessory matched to their existing 4U layout.

Before ordering, check that the collar fits your rack or swing frame system, including the mounting style and the 100 mm measurement, so it works with the equipment you already have. If you are unsure about compatibility, compare the dimensions with your rack documentation before purchase.

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.
