Do you have one for 1.25 inch rope?
1 Answer
The largest pulley/arborist block we have is for 1" rope (link below).  You may need to switch to a larger snatch block for rigging.  Feel free to call us @ 541-344-6249 and we can help you further.

Can the pin be removed to use on an existing 1/2" aircraft steel wire cable?
1 Answer
The pin can be removed from the RP144, but when the nut on the end is taken off it will not retain the locking function so you will need to put a new lock nut on.  Please note that modifying the product in any way from its original design will shift liability from the manufacturer to you.

Does it come in 3/8"?
1 Answer
No, this pulley only comes in the one size, but you should be able to run 3/8" rope over this small sheave.
