Gibbs ascenders provide excellent
performance under the most adverse
conditions, even with muddy or iced
ropes. They are widely used by rescue
teams as mechanical Prusiks in
systems and rappels. The spring-loaded
model will support its own weight when
there is no load on the cam. Gibbs
ascenders feature a high-quality forged
cam, which provides a product with
no cast parts. The 1/2" ascenders have
undergone several rescue
performance improving
changes. The shell
bottom has been
modified creating a
curved interface,
which improves the
holding power. Also,
the shell thickness has
been increased by 50%.
