💡 How do I stop my workshop cart from drifting on sloped surfaces?
Solving rolling drift takes proper stem sizing and quality tread compounds. Here is how you keep your setup handy:
- Match the steel stem thread length to your cart base thickness for solid grip
- Pick sealed radial bearings to keep grit out during heavy shift operations
- Bolt down the quad pack layout to spread peak load capacity evenly
- Slam the toe locks tight whenever you park rolling tools or parts bins
