Micro U-Rack

Single Rope Technique is becoming mainstream in tree work both for canopy access and utilizing hybrid systems that allow work to be conducted on a single line. Seattle Manufacturing Corporation (SMC) has built extremely high quality gear for all high angle disciplines for 45 years. The new Micro Rack is the best choice for descending trees in the 125' to 300' range. There is no better device for long rappels than a rack.

The U-Rack utilizes Hyper bars which makes it easy to add friction or lock off the device. The rack dissipates heat excellently while still giving the needed amount of friction for long rappels. SMC tests their equipment in the user configuration which gives very accurate ratings. This rack is designed to run on ropes from 7-12.5mm and has a MBS range of 8kN to 22kN which corresponds with ropes you would use it with. At 9” x 3’ it is the most compact rack from SMC.

Rated: Good Review by: Scott A.

“ The staff at Wesspur recommended this rack for rappeling. I am on a wildlife snag creation project for U.S.F.S. and have used this rack for rappeling down from 50+ feet over 100 times in the last year. It shows no sign of wear on the bars. I have used it mostly with 3/8ths line. With chainsaw and gear, I weigh over 250lbs. It provides just the right friction with one wrap over the top ear. Easy to wrap the ears and tie off when needed. My only complaint is that the bottom bar is tough to unsnap from the u-rack. This might be a designed safety feature to ensure the bar stays in place if slack gets thrown into your rappel line from below. This product is well made. Would recommend.”
