Does anyone know the measurements of all the vendors pulleys? For instance, I thought I had a 6lb pulley from Metco, and I matched it up to REM's 4lber that my friend has an its the same. It measures at about 9.25". Anyone know the sizes of 4lb 6lb and 8lber's of all the different vendors? Thanks

The LFP/Metco pulleys were a bit smaller before, but the new ones are the correct size.

 

Any ideas of the size of the newer Metco pulley's?

not sure, just know that they are the correct "standard" size for 4#, 6#, 8#'s etc
