Question: Is this a single pulley or two pulleys?  The package quantity says 1 item and it seems like a pulley system should have 2.
Document: The seller shipped my order quickly and at a good price. This cable pully from Ben-Mor Cables Inc. is 6.5" diameter, rather than 6.5', as stated. The hanging stand is an aluminum alloy and the pulley is mounted on a stud as the axyl and seems to be well designed as pulleys for clotheslines go. I like it for my squirrel proof bird feeder hanger/mover.
We couldn't find any of these heavy duty pulleys to replace the ones on our clothesline. These are great and work so much better than what we had before. Rolls so smooth and easy. Great pulleys.
works great and really strong. my wife hangs large loads of laundry on our line so we needed a really strong pulley
I ordered this assuming that it would handle at least a 500 pound load when used with the appropriate rope. I will keep the pulley for light duty use. My advice is don't trust it for 500 pounds. The center pin for the pulley is also aluminum and appears to be very weak.My original intention was to use the pulley to lift a 400 pound Ingersoll-Rand compressor. I changed my mind after seeing the pulley and made other arrangements to do the lift.Beware - its a clothesline pulley only!
happy with the construction, lightweight but strong enough to do the job - not flimsy at all. I think they are pot aluminium? ?
This product should last longer than the plastic ones I had previously. It is reasonably priced and as far as I can tell after a short use, well made.
Kinda low quality, but for minimal use it work fine
Decently cast, attractive (for what it is) and excellent quality. Works well, sturdy, and unlikely to break anytime soon.Reccomended !
Answer: no
