    PRODUCT OVERVIEW
    A 3U rack case built for a single power amplifier and processor — with rails that adjust from 13.78″ to 18.7″ (350–475 mm), so shallow wireless gear and full-size amps both fit. The round- and square-hole rails ship with a screw adapter kit; the trolley handle and caster board (with trolley) are sold separately.
    INSIDE MEASUREMENTS
    WHO IT'S FOR
    • Independent engineers and one-amp rigs — one case that adapts as your gear changes, from a wireless rack today to an amp rack next season.
    • Solo and duo touring acts — the whole PA in a case that fits a hatchback, with rails you can re-set when a new processor arrives.
    • AV and IT field technicians — 3U of switches, encoders or a short-depth server, with round- and square-hole rails that match whatever mounting hardware the job calls for.
    • Backline and rehearsal rooms — a permanent home for the amp that never leaves the room, but still survives being moved twice a month.
    FEATURES
    • Adjustable Rails, 13.78″ to 18.7″ — The feature that defines this case. Front and rear rails slide across a full 5-inch range (350–475 mm), so shallow wireless gear and deep power amplifiers both mount correctly in the same shell. No other molded rack case offers this — fixed-depth cases force you to buy twice.
    • Round-Hole + Square-Hole Rails, Adapters Included — One rail is drilled with round threaded holes, the other with square holes that take cage nuts. The included screw adapter kit lets you switch mounting style on either rail, so the screws that came with your specific gear always have a home.
    • One Amp, One Processor, One Box — Three rack spaces laid out the way a single-amp rig actually gets built: a full-size 2U power amplifier with a 1U signal processor, wireless receiver or power conditioner above it. No wasted U, no oversized box to move.
    •  21″ Body, 18.7″ Rail-to-Rail Depth — Deep enough for a 15–17″ amplifier plus rear heat sinks, handles and connector tails, yet only 3U tall, so the footprint stays small enough for a single tech to handle alone.
    • Modular, Detachable Trolley Handle (Optional) — Add or remove the handle yourself, without tools. Buy the standard case now and retrofit the handle later — no need to purchase a separate wheeled case when your rig grows. Shop the detachable trolley handle.
    • Stacks Loaded, Locks Together — Interlocking molded grooves let fully loaded cases stack without sliding apart in a van or backstage, and the shell carries the weight of a packed rack on top.
    • Matching Trolley Board (Optional) — A companion board with a telescoping handle: push a stack like a dolly, or extend the handle and pull it behind you. One board, every way you need to move. Shop the trolley caster board.
    • Dual-Wall Molded PE Shell + Watertight Gasket — A reinforced polyethylene body with molded corner protection that shrugs off loading-dock knocks, and a gasket seal that keeps rain, dust and grit off the gear inside.
    • 19″ EIA-310, IT and AV Ready — The same rails accept rack servers, network switches, AV encoders and broadcast hardware, so the case is not locked into audio.
