Slotted J-Bolt Battery Hold-Down Bar
A ribbed top bar that clamps a 12 V battery into its tray using the tray's two existing M6 or 1/4 in J-bolts. It replaces the snapped or corroded OEM hold-down. The bar is 170 × 28 mm with ribs 17 mm tall. The 6.8 mm slots at each end take any bolt spacing from 110 to 160 mm, which covers the U1 mower and garden-tractor batteries and the small ATV and motorcycle batteries whose trays leave them rattling. For engine-bay heat, order it in PETG or ASA.
