DMM Catch


Sorry this item is currently out of stock. Please contact us if you have any questions


We have been using this for a few years now and really like it! A bit delicate at first but once you get used to it we find it really nice. Rated for use with a cow's tail on a sit harness, so about the only thing designed and tested for how most setters work. Also rated for rescue loads.


The Catch is a towable rope adjustment device conforming to
EN 12841:2006 Type A.

The device features non-aggressive stainless steel cams which are spring loaded allowing it to be positioned on the rope while the user is working.

The towable release mechanism (patent applications EP2641635, GB2500483) allows the user to tow the device while simultaneously descending.
