Desmond DLVC-50 Skeleton Lever Release Clamp Preview

Desmond DLVC-50 Lever Release Skeleton QR Clamp
I don't know how they manage to do it at Desmond, but they keep on releasing good quality and innovative products at astonishingly low prices.

This time they came out with a hot product, an Arca-Swiss® compatible Quick Release clamp with an adjustable Lever-Release just below $30 !

And that's only part of the story, as the new Desmond DLVC-50 design is based on the successful DAC-X1 Skeleton QR clamp reviewed last October, weighing only 70gr (2.5oz) !!

The clamp
Manufacturer Specification:
Height:14.0 mm (0.55 ")
Jaw Length:50.0 mm (1.97 ")
Metal Converter:3/8"-16 to 1/4"-20
Weight w/ Bubble Level:70 gr (2.50 oz)

Desmond DLVC-50 Skeleton QR Clamp - Lever Release positions
Much like the DAC-X1, the DLVC-50 is made totally out of Aluminium with no rubber parts. A very elaborate design with curved beams instead of the usual flat surfaces, two safety-screw relief openings on the sides and a countersunk hole in the center which is also threaded 3/8"-16.
Both clamp jaws feature laser engraved decimal scales with short lines in 1mm increments. Longer lines with digits are set in 5mm increments. Zero (0) defines the center of the clamp and numbering increases from the center, outwards.
The clamp is equipped with a quite large removable bubble level held in place with two M3 screws.
The Lever Release has three rest positions: closed, half open permitting lateral adjustments and fully open which enables inserting or removing an Arca compatible plate or rail from top.

The bottom is indicative of the carving performed on this clamp in order to minimize weight. Whatever could not be removed completely it was hollowed out. Across the center hole exist cross type alignment/anti-twist grooves. With this type of anti-twist grooves the clamp may be easily re-oriented by 90° increments on certain heads especially monopod heads and some multipurpose rails with matching anti-twist bosses.

Innovation comes with the Lever Release design. The clamp jaws are user adjustable with a provided Allen hex key via a hex socket screw in order to meet the widths of any Arca style dovetail while the screw is captive safeguarding from accidental complete unscrewing and loss of parts. Further, the release Lever may be easily re-oriented for left / right hand use. And furthermore but very important, the Lever itself is designed cleverly, its rounded edges and shape embrace the clamp's side, in this way any straps etc will slip off rather than catch on it and open the clamp accidentally. On the other hand the large hole gives ample grip for easy opening / closing of the clamp even wearing gloves.

The DLVC-50 is accompanied by two Allen hex keys appropriate for the Lever-Release adjustment and the bubble level screws and a metal 3/8"-16 to 1/4"-20 conversion bushing.

Desmond DLVC-50 is proof that innovation can be affordable from everybody. As soon as I have a production sample I shall try to elaborate more and evaluate its functionality. So stay tuned.

I hope you found the information useful, thank you for viewing.

  1. Why is this clamp not sold anymore? is there a better replacement?

    1. Desmond who had originally introduced this clamp, was forced to withdraw it from the market, due to legal action by RRS who consider that any lever release design infringes their lever release clamp patent.
      Unfortunately, even if not true, the sum required to bring the case in court is enormous compared to the profits ever to be made from a QR clamp or similar items. Therefore, it would be unwise to continue.
      For the same reason, you won't be seeing any lever release clamps introduced in the US market until RRS patents expire.
      Anyhow, if you are still interested I have updated the availability links in the post above, where you can find some on eBay.
