Nowadays, many tripod top mounting plates are equipped with a reversible stud which has both 3/8"-16 and 1/4"-20 threads, one at each side.
On the other hand, there are some older and a lot of contemporary professional tripods that have only a 3/8"-16 stud on their top mounting plate.
Take for example all flat top tripods without center column, like Gitzo's and Feisol's, as well as most of the Manfrotto's. There comes the need for a 3/8" to 1/4" reducer in order to attach equipment with only an 1/4" socket. And Desmond DTR-1 does exactly that!
|Base Diameter:||59 mm (2.3")|
|Height:||20 mm (0.79")|
|Top Mounting stud:||1/4"-20 UNC|
|Bottom mounting thread:||3/8"-16 UNC|
|Its diameter of 59mm fits on most tripod top mounting plates and is wide enough to hold a big number of gear with an 1/4"-20 bottom hole.|
Used as a spacer
Despite its original purpose as a reducer, DTR-1 may also play the role of a spacer in situations that a flat top tripod would restrict the functionality of a low profile ball head.
Having in mind some comments I read, in a few reviews recently, I found that DTR-1 would be the solution for the owners of Gitzo® systematic or Feisol® tripods (without a center column) who would like to use a low profile ball head like the Sunwayfoto XB-44
|Just by adding a 1/4'-20 to 3/8"-16 conversion bushing on top of DTR-1 you may have a nice spacer...|
|...that will allow full tilting of the head clamp in any direction. Without fearing the bubble level hitting on the tripod mounting plate.|
|While it would also permit full side tilting of a camera in portrait orientation, once again avoiding to hit on the tripod large top mounting plate as the ones found on Gitzo's and Feisol's among others.|
Excellent machining and finishing.
Excellent structural strength.
Very good price.
A very nice and low priced solution for anyone in need of a thread reducer or even more of a sturdy and vibration free spacer.
