I was repairing my old Keller 3520 ladder that needed repairs; Pulley, rope, flaps and side protection above. I considered finding another pulley for less than $15 or just a metal pulley as only the plastic pulley on my ladder was damaged, but this got good reviews and I knew it would work. My original ladder roll didn't have a rivet on it and I never realized this was a problem. I really didn't feel like drilling the whole stair and I don't have a riveting tool. It's good that they include the rivets you need if you want to use one, but I ended up putting a zip tie on either side and it works great for keeping the pulley centered. In general it works great.
