Heavy duty weldable dump trailer door hinges four pack

✅ Built in lubrication channel pairs with external zerk fitting for easy greasing
✅ Max travel limits at 240 degrees to clear side rails on flatbed trucks
✅ Weld on strap architecture allows direct fusion to trailer chassis frames
✅ Ships as a complete four pack assembly finished with matte black powder coat

💡 How often should truckers pump grease into tailgate pivot brackets to keep heavy gear humming in winter?
Stick to a monthly service run to flush out road salt and stop metal seizing quick. These handy habits will save you cash on replacements.
- Squirt waterproof bearing grease straight into the nipple until fresh lubricant pushes the old sludge out
- Scrape off dried mud and grit from the strike plate before it grinds down the mounting surface
- Give the anchor bolts a solid crank after the first cold snap to kill frame rattling and misalignment
