First of all thank you for a rapid delivery - about 3 days only.
I wanted this pulley to hoist an old (and absolutely huge) CRT monitor into the loft for storage. It weighed a ton and I slipped a disc a couple of years ago, so must be careful what I lift and how etc.
The pulley is basic but in fairness it does the job nicely, and is robust enough for most home purposes, but is not very heavy duty or professional quality.
My task involved some extremely careful fixing of hooks plus extra ropes and attachement cords to make sure everything was strong and secure. Next I climbed into the loft and slowly and steadily started hoisting. All went well but the polypropolene cords did tend to twist round for no apparent reason ! I was able to hold the pulley rope with one hand and pull the monitor towards me with another when it was high enough though. The 6:1 mechanical advantage seemed about right.
Job done after no more than ten minutes and much care and forethought. You cannot lose your concentration ! Previous reviewers are right - wear thick gloves.
A worthy addition to anyone's garage, boat or storeroom. Good to know you have it even if you only use it quite seldom.
