Lowe's (not Home Depot) sells some suitable pulleys in their rope section. I have two of the larger ones that I've used with 7/16" and 1/2" rope as a snatch block and/or block-and-tackle. Around $40 each. They have a snap hook attached. Mike N2MG >I have some 3/8 inch rope=20 need a few strong PULLEYS for tower project - any recommendations? need to attach to Rohn 45
