The SARHW04 rack rails are built for touring professionals, venue techs, and mobile DJs who need reliable replacement hardware for their rack cases. When road cases take a beating and rails get damaged or stripped, these heavy-duty steel rails get your gear rack back in service fast.

Each pair provides full 12-space (12U) mounting capability with precision 10-32 threaded holes every 0.625 inches. The 11-gauge cold-rolled steel construction handles the weight of power amps, processors, and wireless systems without flexing, while the black powder coat finish resists chipping and corrosion from constant handling.

At 21 inches long, these rails fit standard PA rack cases, road cases, and ATA flight cases. The 1.55" x 0.68" cross-section provides the strength needed for heavy amplifier loads during transport and setup. Full-hole design gives you maximum mounting flexibility for any rack gear configuration.

Professional audio techs use these rails to repair damaged tour cases, upgrade lightweight consumer racks, or build custom rack solutions for permanent installations. Mobile DJs rely on them to keep multi-amp systems secure during frequent load-ins. Church sound teams often stock extras for quick repairs to sanctuary rack systems.

Installation requires standard 10-32 machine screws (not included). Each pair includes left and right rails with pre-drilled mounting holes for easy case installation. Seismic Audio backs these rails with professional-grade construction and fast shipping to keep your shows running.

Technical Specifications

Frequently Asked Questions

What rack cases are compatible with these 21-inch rails?

These rails fit any standard 12-space PA rack case, road case, or ATA flight case with 21-inch depth. They're designed as universal replacements for damaged or worn rails in touring cases, permanent installation racks, and mobile DJ setups. The 11-gauge steel construction handles heavy amplifiers and processors commonly mounted in professional audio racks.

Do these rails come with mounting screws?

No, mounting hardware is not included. You'll need 10-32 machine screws to attach the rails to your case. Most hardware stores carry these screws, or you can order them separately. The rails have pre-drilled holes that align with standard rack case mounting points for straightforward installation.

How much weight can these rails support when fully loaded?

The 11-gauge cold-rolled steel construction easily handles typical rack loads including multiple power amplifiers, wireless receivers, and signal processors. The full 12-space capacity allows mounting of heavy gear like Crown or QSC amplifiers without flexing. Professional touring companies rely on this gauge steel for flight cases carrying thousands of dollars in equipment.

Can I use these to build a custom rack from scratch?

Yes, these rails work well for custom rack builds when paired with appropriate case materials. Many venues and churches use them to create permanent installation racks or upgrade lightweight consumer cases. You'll need to drill mounting holes in your case material to match the rail mounting points and use proper 10-32 hardware.

What's the difference between full-hole and half-hole rack rails?

Full-hole rails like these have threaded mounting holes every 0.625 inches (every half rack space), giving you maximum flexibility for positioning equipment. Half-hole rails only have holes at full rack space intervals. Full-hole design is preferred for professional applications where you need precise positioning of processors, wireless systems, and other 1U gear.
