istarusa WOS-990 Open Rack Frame — 4-Post 19" Open Frame with Casters

Compact yet capable, the istarusa WOS-990 Open Rack Frame is a versatile 19" open-frame rack designed for mobility, accessibility, and value. Available in 600mm and 900mm depths, this four-post frame supports standard rack-mount equipment while offering easy front-to-back access, excellent airflow, and simple relocation across rooms or labs. Built with a durable aluminum/steel construction, it balances strength with lighter weight for convenient handling in dynamic IT spaces.

• Robust 19" open-frame design for flexible rack-mounting — The WOS-990 uses a four-post open frame that delivers a sturdy platform for servers, switches, storage enclosures, and other 19" equipment. The open architecture makes front and rear access seamless, which simplifies maintenance, upgrades, and hot-swapping of gear. With a focus on ventilation and visibility, this design helps keep equipment cooler and easier to service, reducing downtime and improving uptime for critical systems. Whether deployed in small lab environments or larger data centers, the 19" standard ensures broad compatibility with a wide range of devices from different vendors.
• Two depth options (600mm and 900mm) for versatile deployments — Choose the depth that best fits your gear profile and space requirements. The 600mm version is ideal for compact rooms, test benches, and edge installations where floor space is at a premium, while the 900mm option accommodates deeper servers, PDUs, and larger storage arrays. Both depths maintain the universal 19" mounting width, ensuring compatibility with common rack-mount equipment and making it easy to mix and match components as your infrastructure evolves. The open-frame design promotes efficient airflow across devices and across cables for easy cooling management.
• Mobility with casters for effortless reconfiguration — Equipped with casters, this open rack frame can be rolled between locations with minimal effort, making it perfect for dynamic IT environments, training rooms, or temporary deployments. Mobility helps you reconfigure data centers, labs, or classrooms without heavy lifting or dedicated downtime. The ability to move equipment quickly also supports proactive maintenance windows, site migrations, and rapid responses to changing rack layouts as needs shift. The casters contribute to a flexible, scalable solution that adapts to evolving workflows while preserving stability when parked in place.
• Lightweight, durable aluminum/steel construction — A thoughtful blend of aluminum and steel delivers a balance of strength and manageable weight. This combination supports heavy, rack-mount gear while remaining easier to transport and install than fully enclosed metal cabinets. The frame’s construction enables confident mounting of devices, reliable support over time, and a long service life in demanding environments such as data centers, laboratories, broadcast suites, and IT closets. The mix of metals also contributes to a modern, professional aesthetic that fits well in contemporary IT spaces.
• Cost-effective, open-frame solution with easy maintenance — The WOS-990 is designed to minimize total cost of ownership by eliminating the need for heavy doors and panels while delivering essential protection, airflow, and accessibility. Its open-frame profile reduces material costs and weight, easing installation and relocation. Maintenance is straightforward: remove or rearrange equipment with simple front-access mounting, route cables behind devices, and perform quick inspections of rails and fasteners. This practical design provides reliable performance without unnecessary complexity or added expense.
