Product Overview
The DMMADAPT is a 7-inch adapter plate that mates to any of Losmandy's DUP dovetail plates to create a male-to-male dovetail. Bolted to a plate you already own, it turns a plate with a flat underside into one with a dovetail on both faces.
Who It's For
This is the economical route to a male-to-male dovetail if there is already a DUP plate in the accessory box. Rather than buying a dedicated DMM bar, this piece bolts to the DUP and produces the same arrangement — useful for side-by-side work, or for mounting something that came with a saddle instead of a plate.
Key Features & Design
- 7-inch adapter plate that creates a male-to-male dovetail.
- Mates to any Losmandy DUP dovetail plate.
- Machined aluminium, to the D-series profile.
Recommended Uses
Converting a DUP plate you already own into a male-to-male dovetail. Side-by-side builds where one face needs to clamp into a second saddle. Mounting secondary equipment that arrived with a saddle rather than a plate.
Compatibility and Accessory Notes
- Plates: any Losmandy DUP plate — the 14", 19" or 24".
- Ready-made alternative: the DMM7 and DMM14 are single-piece male-to-male bars, if you would rather not stack two parts.
- Saddles: the resulting dovetail clamps into any Losmandy D-series saddle, including both saddles on the DVSBS and the AZ8.
Good to Know Before You Order
- It needs a DUP plate to work. On its own it is half of an assembly — if you do not own a DUP, a one-piece DMM bar is the simpler purchase.
- Losmandy publishes no weight for this part. It is a small piece; our listed shipping weight is our own figure rather than a Losmandy specification.
- A stacked assembly is slightly taller than a one-piece male-to-male bar, which shifts the balance point of whatever sits on top.
- Specifications are Losmandy's published figures.
Frequently Asked Questions
Is it difficult to set up?
No. It bolts to the DUP plate, and the assembly then clamps into a saddle at either face.
What does it actually do?
It gives a DUP plate a second dovetail face, so the plate can clamp into a saddle on both sides instead of bolting to rings on one.
Which plates does it fit?
Losmandy states any of the DUP dovetail plates.
Why not just buy a DMM bar?
If you do not already own a DUP plate, that is usually the better answer. This part exists for people who do.
Can I use it for side-by-side mounting?
Yes — that is one of the common reasons to need a male-to-male dovetail.
Bottom Line
In short: a 7-inch adapter that bolts to any Losmandy DUP plate and turns it into a male-to-male dovetail — the cheaper route when the DUP is already yours.
