"When I opened the magnetic case, I was just so amazed at how beautiful this trolley is! Picking it up, I could feel the quality immediately. I am a recreational tree climber who understands hardware quality. Being able to remove the trolley easily from the cable is a big plus. We live near salt water and know certain metals react to salty air, so this stainless steel is a game-changer. Accommodates both my 225 lb husband AND our grandkids seamlessly!"

"I ordered a cheaper aluminum trolley previously. After the first few uses, flecks of aluminum started shaving off the wheels from friction against the cable. I ordered the CTSC stainless steel trolley to replace it. This one never flecked any metal at all and showed zero wear after full days of continuous riding. Extremely rugged piece of equipment."

"This trolley is a piece of stainless steel art and built like a rock. I picked it over aluminum because durability is essential and I love that it uses bolts with nylock nuts rather than pressed axle pins. The included locking carabiner is rated at 5,600 lbs and is top-notch quality on its own. Highly recommend this setup!"

"Performs exactly as it should. It's substantial stainless steel rather than thin aluminum, so it feels incredibly solid. Glides effortlessly down the line with minimal resistance."
