The large opening of the ascender above the handle is big enough to enable the use of reinforced gloves. Manufactured of aluminum, the Anthron fits ropes 8mm - 1/2" in diameter.

The Bloquer may be used as a chest or small ascender. It attaches to the harness with flat webbing or carabiner. Features an auxilliary hole into which a second carabiner can be inserted, preventing the rope from falling out of the groove during climbing.

Handle with ergonomic grip for comfort and thermal insulation. Trigger cam with teeth and cleaning slot: works even on dirty or icy ropes. Ergonomic spring-loaded catch is easy to use even when wearing gloves.
