重量片升級套件：選擇式滑輪高位下拉與低位划船機（4000/5000系列）

Took me an afternoon to bolt on, but once it was mounted, the low row station feels rock-solid—no wobble even at heavy stacks. Love that I can switch from pulldowns to rows without leaving my rack.

The pin selector moves so smoothly between weights that I actually look forward to switching plates now, and the low row attachment feels rock solid against the rack frame. Took about an hour to bolt everything on, but the cable path is clean with zero binding through the full range of motion.

Adding a selectorized stack to my lat pulldown was a game changer—the low row attachment glides so smoothly I actually look forward to leg day. It took about 20 minutes to install, and now switching between exercises takes just a second.
