Technical Details

I acquired my S.E.Peak SA-207L & SA-207R from Amazon.com in 2023

Each S.E.Peak is 47 mm. tall, 73 mm. wide, 28 mm. thick, and weighs 101 g bare and 142 g. including the supplied harness. The body is stamped from aluminum alloy. The stamping is bent to form a 16 mm. rope channel at the heel side and a cam channel at the toe side. Four slots on the rear and two slots on a tab at the bottom provide secure attachment for the supplied harness. A 13 mm. hole below the cam serve no apparent purpose, as it is blocked by the cam safety.

The cam is cast steel. The cam radius increases from 37 to 54 mm. over an angle of 38°, giving a 30° cam angle. The tooth pattern is (3.4)(1S1)^2(2S2)(1S1)^3(2.3.2.2.3).There is a spring-loaded plastic safety catch riveted below the cam.

Each S.E.Peak comes with a harness made from 20x1.6 mm. webbing webbing. One piece of webbing circles the ankle, another goes under the instep. A two-piece buckle allows adjusting the strap around the ankle. The strap under the foot is adjusted at the ascender slots.

The front of the rope channel is printed with the S.E.Peak logo with "S.E.Peak," "EN567:2013," a hollow up-pointing arrow with "UP" inside, and "Ø8-13mm." The front of the cam channel is printed with "SA-207L for the left and "SA-207R" for the right ascender.

Comments

Connecting the harness directly to the shell saves weight, but the cam can drag on webbing, possibly causing the cam to stick.

Foot ascenders such as this don't fit into the climbing systems that I commonly use, although I have met froggers that seem to like them (but they also like the frog).
