JMI Wheeley Bar Accessories collection — tie-down brackets, battery pack holders, wheel upgrades and motor drive for telescope dollies

JMI Wheeley Bar Accessories

Every JMI Wheeley Bar can be upgraded to suit your site and setup. This collection covers the full range of official Wheeley Bar accessories — tie-down safety hardware, battery mounting, wheel and terrain upgrades, leveling hardware, tow handles, and the motorized drive.

What's in this collection

Universal-style upgrades — tie-downs, battery holders, 5″ and 10″ wheels, soft-ground feet, leveling screws, tow handles, and the motor drive — plus Triangle-Style Dobsonian upgrades (leveling and caster kits). Most wheel and leveling accessories come in 5/8″ and 1/2″ versions, so match your bar's leveling-screw diameter before ordering.

Choosing the right accessory

  • Terrain: 5″ polyurethane wheels for cracked or seamed hard surfaces; 10″ pneumatic wheels for grass, dirt, and gravel.
  • Leveling-screw size: 5/8″ for current HD bars; 1/2″ for Standard Medium and older HD models.
  • Safety: the Tie-Down Bracket Kit is recommended for every setup — use the Half Kit on the HD Shorty.

Not sure which version fits your bar? Measure your leveling-screw diameter, or contact us before ordering.
