JMI Triangle-Style Wheeley Bar — Dobsonian Dolly for 8″, 10″ & 12″ Telescopes

The JMI Triangle-Style Wheeley Bar is a three-wheeled Dobsonian dolly designed specifically for 8-inch, 10-inch, and 12-inch Dobsonian telescopes. Its triangular wheel layout provides stable, easy rolling on flat surfaces at an accessible price point. Made in California, USA.

Product Overview

The Triangle-Style Wheeley Bar uses a three-point triangular wheel configuration — one wheel at each point — rather than the rectangular frame used by the Sky Trekker and Universal series. It fits Dobsonians in the 8-inch to 12-inch class and provides a stable rolling platform for storage and transport on hard flat surfaces. Ships with 5″ locking caster wheels.

Who Is This Product Best For?

Owners of 8-inch, 10-inch, and 12-inch Dobsonians who want a simple, affordable rolling dolly for hard surface use. A practical entry-level option for Dob owners who want easy roll-in, roll-out storage without the larger investment of a Sky Trekker model.

Why Choose This Product?

• Three-wheel triangle design: Stable, lightweight, low-profile rolling platform.
• 5″ locking caster wheels: Included standard — suitable for garage floors, driveways, and patios.
• Fits 8″, 10″, and 12″ Dobs: Covers the most popular aperture range for Dobsonians.
• Accessible price point: More affordable than the Sky Trekker models.
• USA-made by JMI.

Important Limitations

• For Dobsonian telescopes only — not for tripod-mounted scopes
• Currently out of stock — contact us for availability
• Designed for hard flat surfaces
• Not for very large Dobs — for 14-inch and above, use a Sky Trekker model

Our Recommendation

A solid, practical choice for 8-inch to 12-inch Dob owners who want a simple rolling dolly at an accessible price. For heavier or larger Dobsonians, step up to the Sky Trekker line.
