[ Top | Short | Return to Racks ]
This is a standard length rack of classical design. This rack was designed to accept standard carabiner brake bars (in those days, carabiners had standard sizes, and so did racks). I bought this rack with hollow steel bars, but replaced the second bar with a worn SMC brake bar to help keep the rope centered. The steel bars are somewhat faster than aluminum bars. They don't leave a black aluminum oxide streak on the rope (in those days, PMI rope was white), but so what? The oxide does not appreciably affect the strength of the rope, nor does it appreciably cause the rope to wear out any sooner.

PMI also made a shorter Version Designed for five bars. This is more compact, but has decreases the available range of friction.
