Middle Atlantic SP-5-43 Removable Steel Side Panel

Introducing the Middle Atlantic SP-5-43 Removable Steel Side Panel — a purpose-built accessory designed to elevate the performance and aesthetics of your rack or cabinet system. Built for professionals who demand both durability and ease of service, these Slim 5 side panels are engineered to stay strong under daily use while offering rapid access when you need to service gear or reconfigure your setup. Each panel is designed to add a precise 5/8" to the cabinet’s overall width, preserving the footprint of your enclosure while giving you essential flexibility for mounting, ventilation, and upgrades. Sold in pairs, they provide a balanced, finished look on both sides of your cabinet, ensuring symmetry and professional presentation in any environment.

Crafted for rugged reliability, the SP-5-43 panels are manufactured from 16-gauge steel, a gauge that resists bending, denting, and impact during routine handling, relocation, or reconfiguration. The panels are finished in a durable black powder coat, delivering a clean, modern appearance that complements a wide range of cabinet designs while protecting against scratches, moisture, and wear. The combination of robust steel and a protective finish means these panels maintain their appearance even in busy studios, data centers, control rooms, or industrial settings. Ventilation is thoughtfully integrated with vents at the top and bottom, promoting airflow around enclosed electronics and helping to manage heat buildup — a critical consideration for preserving equipment longevity and performance in enclosed racks. Recessed lift handles provide a secure grip for smooth insertion and removal, while internal locking clips add an extra layer of security to keep the panels in place during operation and transport. By offering this secure yet accessible solution in pairs, Middle Atlantic makes it straightforward to upgrade or replace both sides of your cabinet for a balanced, professional look and reliable service access.

For installers and end-users, the SP-5-43 represents a practical fusion of form and function. The 16-gauge steel construction communicates durability and stability, ensuring panels retain their shape even after repeated removals and reattachments. The black powder coat finish not only looks primed for professional settings but also provides resistance to corrosion and scuffs that can occur with frequent handling. The venting design supports continuous air circulation around internal equipment, which is particularly important in high-density racks housing power supplies, AV processors, and other heat-emitting gear. The recessed lift handles simplify handling in tight spaces, letting technicians grip and remove panels without snagging on nearby cables or components. Internal locking clips are a small but meaningful addition, offering confidence that panels remain securely seated during normal use and accidental bumps. Finally, the precise width addition of 5/8" means you can plan rack configurations with accuracy, ensuring proper fit and alignment in your enclosure’s overall footprint. Together, these features translate into faster service, less downtime, and a more organized, professional rack presentation that supports efficient workflows and reliable performance.

• Rugged 16-gauge steel construction: The SP-5-43 is built from heavy-duty 16-gauge steel to withstand the rigors of daily rack use, transportation, and reconfigurations. This robust construction minimizes flex and deformation, preserving panel integrity and protecting internal components. The steel base also lends stability to stored equipment, reducing wobble and ensuring a solid, professional installation that stands up to demanding environments like broadcast studios, control rooms, and data centers.
• Ventilated top and bottom design: Ventilation is integrated at both the top and bottom of the panel, promoting airflow around enclosed devices. This feature helps dissipate heat more effectively, supporting cooler operation, reducing the risk of thermal throttling, and extending the life of sensitive electronics. Whether you’re housing power supplies, amplifiers, or network gear, the vented design contributes to a healthier environmental profile inside your cabinet.
• Recessed lift handles for easy removal: Each panel includes recessed lift handles that enable secure, low-profile gripping. This design minimizes snag hazards and allows technicians to remove or insert panels quickly, even in tight installations or crowded racks. The ergonomic placement also reduces strain during frequent servicing, making maintenance smoother and faster without compromising safety or control of the panel.
• Internal locking clips for secure engagement: The SP-5-43 panels incorporate internal locking clips that secure the panel in place within the cabinet. This feature provides peace of mind during transport, vibration, or routine handling, ensuring panels stay properly seated and aligned. Secure panels also help prevent accidental gaps that could allow dust intrusion or cable snagging, contributing to a cleaner, safer enclosure.
• Precise width addition of 5/8" and available in pairs: The panels add a precise 5/8" to the cabinet’s overall width, preserving your kitchen-table footprint and maintaining the intended rack dimensions. Sold in pairs, they ensure both sides match for a balanced appearance and consistent airflow, enabling a seamless upgrade or replacement that looks as good as it performs. This pairing also simplifies ordering and installation, letting you outfit the entire cabinet quickly without mismatched parts.
