Technical details

I acquired my Anthron DSD 30+25 new on eBay from Bret Auernig in 2008.

The Anthron DSD 30+25 is 191 mm tall, 79 mm wide, and 27 mm thick. Mine weighs 334 g. It is essentially the same descender as the Antec Double Stop; ANTEC being a former name that Anthron used. The following description is modified from the Antec Double Stop description, with differences shown in black.

The Antec Double Stop consists of a control handle/upper bollard assembly and a lower bollard casting, each pivoting between two 3 mm. stamped aluminum side plates. The side plates have raised portions in their lower half to provide some rigidity. Each plate has a 15.3 by 18.2 mm. pear-shaped hole at the base for attaching to one's harness. The two plates are compressed toward each other at the lower side of the hole. The control handle pivots from a rivet near the top of the side plates. The upper bollard is a 32 mm. aluminum turning mounted on the same rivet as the control handle. The pivoting bollard assembly is a steel casting with integral lower bollard, upper bollard and guide pin. It mounts midway on the frame with a rivet that passes through the approximate center of the lower bollard.

One side plate is printed with the ANTHRON logo, "CE0123", "ANTHRON", "DSD 30+25", "0208-081", a figure showing the normal rigging, "30-150kg", "max 200m,", "EN 341 CLASS A ROPE * 11mm" and "* 10<Ø<12 mm" where the * represents a dot inside a circle). The other plate is stamped with a page icon with an explanation mark beside it, "PROPER TRAINING IS ESSENTIAL BEFORE USE", another figure showing the normal rigging (a mirror of the other side - one is looking at the reverse), and "PATENTED."

Comments

The comments that I made for the Antec Double Stop apply to the ANTHRON DSD30+25 as well.
