The Scanstrut ROKK Midi RLARM is the adjustable body and rail mount base component of the modular ROKK Midi mounting system. Designed for installing fishfinders, chartplotters, and other small electronics at the helm, RIB console, nav station, or fishing boat dashboard, it provides a multi-position, fully adjustable platform that holds devices securely in any on-water condition.
This listing is for the adjustable body and rail mount base only. A complete ROKK Midi installation requires two components: a body with mount (this item) and a compatible top plate or clamp, ordered separately.
Rail Mount Base
The RLARM mounts directly to standard round rails, making it well-suited for helm rails, T-tops, hardtops, and console rails on powerboats, RIBs, and centre consoles. No drilling into the helm surface required — the rail clamp provides a secure, removable attachment point.
Multi-Position Adjustable Body
The articulating body allows the mounted device to be tilted, swivelled, and locked into virtually any viewing angle. Adjust once for your preferred helm position and lock down — the mount holds its position under vibration and wave action without creeping or shifting.
Built for Larger Devices
The ROKK Midi platform is sized for fishfinders, chartplotters, and larger tablets — devices that require a more robust mounting body than the compact ROKK Mini system. If you’re mounting a smartphone or small device, the ROKK Mini system may be a better fit.
ROKK Mini Top Plate Compatible
All ROKK Midi top plates are cross-compatible with the ROKK Mini system, and ROKK Mini top plates fit the ROKK Midi body — giving you flexibility to mix components across both platforms as your electronics setup evolves.
Parts Desk Insights
- Best Use Case: Ideal for powerboat and RIB owners who want a secure, rail-mounted position for a fishfinder or chartplotter at the helm or console without drilling into the dash. Particularly effective on centre consoles and RIBs where a stainless or aluminum helm rail is already present and provides a natural, accessible mounting point.
- System Build — What Else You Need: This body and rail mount must be paired with a compatible ROKK Midi top plate or clamp to complete the installation. Top plates are device-specific — select the correct plate for your fishfinder or chartplotter model. Top plates are sold separately and not included with this item.
- Rail Diameter: Confirm your rail diameter is within the RLARM’s clamp range before ordering. The rail clamp is designed for standard marine rail diameters — refer to Scanstrut’s specification sheet for the exact range.
- Deck Mount Alternative: If your preferred mounting location is a flat deck or helm surface rather than a rail, see the ROKK Midi Adjustable Body with Deck Mount for a surface-mount version of the same body.
- ROKK Mini Cross-Compatibility: ROKK Mini top plates — including the ROKK Mini Phone Clamp and ROKK Mini Tablet Clamp — are compatible with this ROKK Midi body, allowing you to use a smaller clamp on the larger, more adjustable Midi body if needed.
