Twin Pipe-Clamp Cross Bar — Rail-Mount Bar for Modular Kits (Parametric, 3D Print)

🔖 Art. ML3D_0053

Twin pipe-clamp cross bar by MarineLab3D — a flat bar with a 2-piece pipe clamp at each end (from the Pipe Wall Clamp ML3D_0047), so you can mount it across two parallel tubes, rails or guardrails with no drilling. Each clamp sits on a saddle seat with a 4.1 mm stand-off, bolted to grip the tube. Set the collar bore and the bar length (centre-to-centre of the two tubes) and receive your STL files. 🔧 Two 2-piece clamps, perpendicular to the bar, on the wide face — clamp to rails/tubes, no holes in the structure. 📏 Fully adjustable: collar inner Ø and bar length (centre-to-centre). 🧱 Saddle seat + 4.1 mm stand-off = solid, precise clamp-to-bar joint. 🔩 Hardware: M5 bolts to close each clamp around the tube. 🔄 **Move your modules where you need them.** Want to relocate a holder for a passage — e.g. take the cabin VHF module outside while under way, or move the Garmin/chartplotter to the helm? Clamp this bar onto a rail or guardrail and hook your module on, no tools on the structure, no drilling. Take it off when you're done. 📐 **Bar length = centre of one collar to centre of the other** (i.e. the spacing between the two tubes/rails you clamp to). 🧩 **Optional rail-mount bar for these MarineLab3D modular kits** — use it instead of the screw-on wall rail to hang the kits on tubes/guardrails: - Modular Jar Kit — Wall Rail + 1–3 Square Jars (ML3D_0041) - Modular Rail Device Holder Kit — 1–3 Holders (ML3D_0042) - Modular Cylinder Holder Kit — Can · Bottle · Pens · Cup (ML3D_0052) 🧵 Print: PETG or ASA, 0.2 mm layers, 3+ perimeters. Prints flat, no supports. You receive a ZIP: bar + 2 fixed half-clamps in one piece, plus the 2 free half-clamps. Use "Customize" to set the collar Ø and the bar length.
