    Super easy

    We use this block for rigging and pulling. Super user friendly with the quarter turn locking mechanism. We used to use a pulley that was a full 3+ turn locking. Was time consuming and annoying. We've had no issues with this pulley.

    Go 2 Block

    This block has been my go 2 for a while now that I've bought 2. Super compact and is super smooth. You can trust this block in any rigging scenario.

    faveorite small block

    This is my favorite as far as the small blocks go. The CMI rigging bock is quick to open and close, built to last, easy to see. my go to when I need more than a basic pully but don't expect to be dropping the real big wood into it.

    You’re going to love this block

    This is a fantastic rigging block or redirect for rope up to 3/4”. Not only is it light and runs well, but it’s even easy to open and close without looking and with or without gloves.

    My #1 block

    This block is excellent and I use it for most of the negative rigging I do. It’s really small, really strong and easy to use. I don’t know of a better, more versatile block for the weight. A few little modifications and lube make the CMI rigging block even better and super smooth.
