I acquired my Proverti CD 201 from Ondřej Belica in 2015.
The Proverti CD 201 is 134 mm. tall, 84 mm. wide, 30 mm. thick, and weighs 219 g. The body is milled from aluminum alloy and then soft anodized. There are two pear-shaped attachment holes. The lower hole is 23 mm. by 18 mm., with the long axis tilted about 45°. The upper hole is larger, 27 mm. by 21 mm., tilted downward so one side is horizontal.
The cam is a skeletonized casting. The cam radius, measured
from the pivot, increases from 36 to 56 mm. over an angle of 45°, giving a 31° cam angle. The cam has number of small conical teeth, all
of which have their axes approximately parallel to the upper surface
of the cam. The teeth are fairly dull compared to those
of other toothed ascenders. In between the teeth rows are four oval holes which
open to the central vacancy of the cam. The holes and teeth both
decrease in size towards the toe of the ascender. The tooth/hole
pattern is (3)(4.H)^2(3.H)^2(3.2.2). A spring-loaded
manual safety bar is mounted on the bottom of the cam with a steel semi-tubular rivet. The normal action of the spring holds
the safety against the cam. When the cam is opened, the shell
interferes with the safety bar, thus preventing opening the cam.
If the safety bar is moved away from the cam (opposing the spring),
it will clear the shell and the cam will open. At full open the
safety can be released and the spring will hold the safety against
the back of the shell. This provides a means of locking the cam
open. The lower portion of the safety is bent outward to form a thumb tab to assist in operating
the safety mechanism.
The cam channel is tilted about 45°, allowing the cam to open farther than a vertical channel would. In the locked open position, the upper surface of the cam is vertical. The rope channel is 16 mm. wide.
The back of the ascender is printed with "PROVERTI," a hollow arrow containing the words "UP" and "ASCENSION," "CD 201," "ROPE O9<Ø<13," the UIAA logo, "EN 567," a book-with-an-"i" icon, "CE0082," a rigging illustration, and "www.proverti.com."
This is a nicely made, rugged ascender, but rather heavy. I would have milled away some of the material behind the cam to reduce weight. Opening the ascender with one had is very difficult. The tab on the safety is rather small, allowing one’s thumb to slip off rather easily.
The cam appears to be copied from the cam on the Kong Cam-Clean.

Technical DetailsI acquired my Proverti CD 202 from Ondřej Belica in 2015.
The Proverti CD 202 is 134 mm. tall, 84 mm. wide, 30 mm. thick, and weighs 219 g. The rope channel is 16 mm. wide. The cam radius increases from 36 to 56 mm. over an angle of 42°, giving a 31° cam angle. The tooth pattern is (3)(4.H)^2(3.H)^2(3.2.2).
The markings on the CD 202 are the same as on the CD 201 except "CD 202" replaces "CD 201," and the positions of the markings are rearranged.
The CD 202 is a right-hand ascender, essentially a mirror image of the CD 201.

Hundreds of cell phone users complained and asked me to for a simpler, mobile friendly site. In particular, they wanted me to limit each page to a small number of pictures and minimize my use of text. This new site provides what they asked for.
