Alesis Tiedown Clamp

Alesis 37.5 mm Electronic Drum Rack Tie-Down Clamp

Secure your electronic drum kit for transport without crushing or marking the rack tubing.

This heavy-duty tie-down clamp is designed specifically to fit 37.5 mm OD drum rack rails, as used on many Alesis electronic drum kits. It provides a strong, reusable anchor point so you can strap your kit down safely on a trailer or ute tray.

Features

• ✔ Designed for 37.5 mm round rack tubing (Alesis standard)
• ✔ Integrated side eyelet for ratchet strap hook or soft shackle
• ✔ Split-clamp design with three bolt locations for even clamping force
• ✔ Large surface contact area to reduce point loading on the tube
• ✔ Compact profile – won’t interfere with existing rack hardware
• ✔ Optimised for FDM 3D printing

Use Case

Ideal for:

• Transporting your drum kit fully assembled
• Trailer, ute tray, or van tie-down
• Securing practice kits between gigs
• Preventing rack movement during relocation

The clamp mounts directly to a vertical rack post and provides a solid tie-down point without relying on cymbal arms or crossbars.

Printing Recommendations

Material:

• PETG (recommended for impact and heat resistance)
• ASA/ABS (ABS-GF shown)for high-temperature environments
• PLA only for light duty / indoor transport

Suggested Settings:

• 4–6 perimeters
• 40–60% infill (gyroid or cubic)
• 0.2 mm layer height
• Print with the clamp bore vertical for maximum hoop strength

Hardware Required

• 3 × M5 × 15 mm bolts
• 3 × M5 nyloc nuts

Notes

• Designed for 37.5 mm OD tubing only. Measure your rack before printing.
• Not intended for overhead lifting or dynamic load applications.
• Inspect printed parts regularly for cracks or fatigue if used frequently.

If adapted for other rack diameters, feel free to remix and adjust the bore size accordingly.
