CMC 3D Rack



SKU: CMC-300880 Category:


Our new 3D locking-bar descender delivers the ultimate in safety,
control and performance, in one compact and lightweight device.
The 3D features two sliding bars for optimum friction control and
efficiency. The horn design works well with 13mm rope and smaller,
making it easy to add or subtract friction as needed throughout
the evolution. The frame dimensions allow for larger rescue-sized
carabiners to be used without any contact or friction with the rope.
The descender can be loaded or unloaded while connected to
your harness for rappelling or to an anchor for one- or two-person
rescue lowers.

About CMC Rescue’s Super Black Finish

Our 3D, Rescue Rack and Rescue 8 products feature an exceptionally
long-wear proprietary finish because typical hard or soft anodizing
on aluminum descenders eventually wears through. The finish
also prevents transfer of material to the rope, common with bare
aluminum components. After years of heavy use, our products and
test samples with our Super Black Finish continue to be used in CMC
Rescue School classes without showing any indication of the surface
wearing through.
