Parametric TUBE/RAIL MOUNT DEVICE HOLDER by MarineLab3D — clamps to a rail, guard-rail, pushpit/pulpit, pole or pipe (no drilling) and holds your gear: tablet, phone/smartphone, Leatherman & multitools, Garmin GPS/chartplotter & handhelds, VHF/remotes, torches and more.

📦 The ZIP contains 4 parts:
• Box/cradle — holds the device, parametric to your size
• M10 nut — locks the joint

🧭 Adjustable SIDE TILT: the box (M10 male) screws into the collar; rotate to the angle you want and lock it with the M10 nut.
📐 Fully parametric box (internal sizes): height, width, depth — set it to fit your device.
