RACKIT is an iPhone-only tool that lets you verify — to the millimeter — whether a network device will fit your server rack before you mount it. Built for data center engineers, network integrators, server room administrators, and site-survey technicians. ■ Be certain before you slide it in. Enter the rack's usable depth, front rail position, rear rail position, device depth, front protrusion, and rear protrusion. RACKIT instantly calculates front and rear clearance and delivers a three-tier verdict: OK / Caution / NG. ■ Depth-Aware Rack Visualization More than a flat diagram — a 3D-style cross-section that conveys real depth. Rail positions, equipment placement, and clearance relationships are intuitive at a glance. OK zones render in green, caution in amber, NG in red — persuasive enough to drop straight into a site report. ■ Rail Position Simulator Drag the rail sliders and everything updates live: overall verdict, individual clearance values, and on-screen labels. The equipment depth itself stays locked; you fine-tune only the rails. Find the sweet spot with your fingertip. ■ Cable Bend Radius Checker • Power cables are visualized on the rack's rear panel side • Fiber / DAC / AOC are visualized on the front panel side True to real-world cabling conventions, including effective protrusion introduced by bend radius — so your go / no-go decision reflects reality. ■ Equipment Library Save the devices you use most with vendor, model, and every dimension. Search to recall instantly, apply to the checker in one tap, and add new entries on site using the floating add button. ■ Safety Margin Presets Switch between 0 / 5 / 10 / 20 mm in one tap. Match internal standards or per-project requirements without retyping. ■ Save & Share Results Name and save calculations. Export the full 3D-style diagram as an image to drop into reports, reviews, or chat threads. ■ Instant JP / EN Toggle Switch between Japanese and English in one tap — ideal for global vendor calls and multinational teams. ■ Built For • Data center install and operations engineers • Network integrators and pre-sales engineers • Server room and comms-room administrators • Rack layout designers • Site-survey technicians ■ Privacy Rack specs, equipment library, and saved results all live locally on your iPhone. Nothing is sent to external servers. Works fully offline. Stop discovering interference when the chassis hits the door. Know before you mount — with RACKIT.
