Description

The JMI Astro-Physics Pier Mount Wheeley Bars are a purpose-built mobility solution designed specifically for Astro-Physics pier mounts. Roll your fully assembled pier-mounted telescope from storage to your observing position without disturbing setup, cables, or alignment. Built by JMI on heavy welded steel with 5″ locking caster wheels. Made in California, USA.

Product Overview

Unlike the Universal Wheeley Bar series — which fits adjustable-leg tripods — this model is custom-engineered for the Astro-Physics pier mount base. If you own an Astro-Physics pier and want to move your complete setup between storage and observing positions, this is the correct Wheeley Bar for your system.

Who Is This Product Best For?

Owners of Astro-Physics pier mounts — particularly those who store their pier-mounted AP mount in a garage or building and roll it outside to an observing pad for each session.

Why Choose This Product?

Custom fit for Astro-Physics pier mounts: Designed to match the specific base geometry of AP piers — no universal adjustment needed.
5″ locking wheels: Smooth, stable roll on concrete, driveways, and patios.
Heavy welded steel construction: Built to support the substantial combined weight of an AP pier and mount.
Session integrity: Keep your alignment, cabling, and counterweight position intact between sessions.
USA-made: Welded steel frame with powder-coat finish.

Important Limitations

Designed specifically for Astro-Physics pier mounts — not for standard tripods
Verify compatibility with your specific AP pier model before ordering

Our Recommendation

If you own an Astro-Physics pier mount and want to roll your setup in and out of storage without rebuilding, this is the only JMI Wheeley Bar purpose-built for your system. Confirm your AP pier model is compatible before ordering.
