Beware DONOT buy the ALUMINIUM WHEEL pully for steel cable ZIPLINEthe cable will eat or burr the pully wheels. For some reason the Q&A and marketing description makes it seem that the lighter aluminum pully is ok for zip line usage it is NOT.ONLY use ALUMINUM on rope i.e non steel cable.

Aucune certification. Aucun papier de mode d'emploi . Pas de roulement métallique comme indiqué simplement des bagues en plastiques. Livrer dans un simple papier bulle. Ce produit est potentiellement dangereux .

I guess we hoped to use this for our zip-line. It's not a ball bearing based trolley. It does not run super fast with weight on it. It works, just not the way we need it to.

Using these to replace a much heavier model pulley on flying trapeze Rig. I have done light testing and so far so good.They need to to be packed & shipped properly in a box , not a padded envelope. The first two were damaged but they replaced them very quickly.

I haven't had a chance to use this product yet but it seems to be of good quality, I'm using it to create a Polley system tho, so more of a special use-case I guess. I like how it looks and seems to be adequate for my needs
