Took me under an hour to bolt onto my rack and the range of motion on the high pulley feels comparable to gym equipment I've used, just without the monthly fee. The steel frame is rock-solid during heavy lat pulldowns, zero wobble. Makes the rack feel like a proper full station now.
Assembly took about an hour, but once it was bolted to the rack, the lat bar feels rock-solid with zero wobble even during heavy sets. The high-pulley range is generous, so I can do full stretch pulldowns without hitting the top frame.
The pulleys glide so smoothly it honestly feels like I added a whole new machine to my setup, not just an attachment. Bolted it to the rack in about 15 minutes and lat pulldowns now feel rock solid with zero wobble.
