Farpoint 7 Inch Metric Universal Dovetail Plate

Product Overview

The Farpoint FMDUPS is a 7″ D-size (Losmandy-compatible) dovetail bar drilled on metric centres: 60mm wide hole spacing, which is the pattern used by William Optics and most Asian-made clamshell rings. That spacing lets those rings bolt straight to the bar without adapter plates or re-drilling. The bar is machined from sturdy aluminum, carries a distinctive blue anodized finish, is CNC-machined in the USA, and weighs 1.375 lb.

Who It's For

This is a good match if you…

• own William Optics rings, or Asian-made clamshell rings, whose mounting holes sit 60mm apart.
• run a mount with a D-size (Losmandy-style) saddle and want the rings to bolt directly to the bar.
• have been working around a mismatch with adapter plates and would rather have the spacing built into the bar.
• are mounting a short refractor or a compact tube where 7″ of bar covers the ring footprint.

Key Features & Design

• 60mm metric hole spacing: matched to William Optics and most Asian-made clamshell rings, so those rings bolt on directly.
• 7″ D-size bar: the Losmandy-compatible profile, the wider of the two common dovetail standards.
• Blue anodized aluminum: the anodize colour distinguishes the metric bars from the imperial universal bars at a glance.
• CNC-machined in the USA: the dovetail angles and hole pattern are cut on CNC equipment at Farpoint's own shop.
• 1.375 lb: a modest addition to the payload on a mid-size mount.

Recommended Uses

• Mounting a William Optics refractor in its supplied clamshell ring on a Losmandy-saddle mount.
• Fitting an Asian-made clamshell-ring scope to a D-size saddle without machining new holes.
• Carrying a guide scope or imaging assembly whose ring spacing is already metric.
• Standardising a rig on 60mm centres so rings and bars interchange between tubes.

Compatibility and Accessory Notes

The bar seats in any mount saddle cut for D-size (Losmandy-style) hardware. Mounts fitted only with a small Vixen-style (V-size) saddle take a V-size bar or a D-size saddle conversion instead. On the ring side, the defining figure is the 60mm wide hole spacing: rings with holes on 60mm centres — William Optics and most Asian-made clamshell rings — bolt straight on. Rings drilled on imperial centres pair with Farpoint's imperial universal bars, which carry a different variety of hole options. Farpoint publishes a customer drawing for the FMDUPS showing every hole option and its measurement. Send us your ring or scope model and we will check the spacing for you.

Good to Know Before You Order

• Metric refers to the hole pattern, not the dovetail. The dovetail profile is the standard D-size Losmandy shape; only the mounting holes are on 60mm metric centres.
• The bar ships on its own. Rings, tube screws, and saddle hardware are separate items.
• Imperial rings need a different bar. Rings drilled on imperial centres pair with the 7″ or 14″ imperial universal bars rather than this one.
• 7″ is the shortest metric length. Farpoint also makes the same 60mm pattern in 10″ and 14″ bars for longer tubes or wider ring separation.
• Bare aluminum dovetail edge. Saddles that clamp with a set screw bear on the anodized edge; saddles with a clamping bar spread the load across the face.

Frequently Asked Questions

What makes this bar metric?

The hole spacing. It is 60mm wide, matching William Optics and most Asian-made clamshell rings, so those rings mount with no adapter plates and no re-drilling. The imperial universal 7″ bar carries a different variety of hole options instead.

Will my rings bolt to it?

Rings with 60mm-wide hole spacing will, which covers William Optics and most Asian-made clamshell rings. The Farpoint customer drawing lists the hole options against which your rings can be checked, and we are happy to check it with you.

What mounts does it work with?

Any mount with a D-size (Losmandy-style) saddle. Mounts with a small Vixen saddle can take a D-size saddle conversion.

Is it difficult to install?

Installation is bolting the rings to the bar through the 60mm holes and sliding the assembly into the saddle. It calls for hand tools and no modification to the bar.

Why is it blue?

The blue anodize marks the metric bars apart from Farpoint's black anodized imperial bars, which is useful when a rig carries both.

Bottom Line

In short: a 7″ blue anodized D-size Losmandy dovetail bar at 1.375 lb, CNC-machined in the USA and drilled on 60mm metric centres so William Optics and most Asian-made clamshell rings bolt directly to it.
