FOREARM BARS

There are plenty of execises such as towel chin-ups, farmers walks and rope climbs that will do the job much better and won't cost you anything.

Unless a specific rehab situation calls for it, there really is no need for writst flexion/extension isolation work.

Any Video demonstrations ? Especially the
farmers walk. Just to make sure I'm on the same page. It looks like a good device and has good reviews. We've used the wrist rollers but I thought this was more intense. I like the rope climbing and towel work idea.

Just viewed a farmers walk. Can we use heavy dumbells or walking with 2 bars with weights on both ends to make it harder for balance.

I personally like two barbells with weights on end. Makes for a great challenge.

Do you best to secure a thick climbing rope. Yes, the same one that used to be in every HS gym just a few decades ago. That will make the monster bar look like the thigh master

How thick for the rope ? Any sources for this rope. I searched some sights but it was only half inch thick.

check this link, they offer up to 3 inch diam. that should be more then thinck enough, huh?

Great link Dan. Just don't go too thick at first as it will provide too much of a challenge. If the budget allows buy 1 1/5 and 3 inch for when your players adapt.

You certainly do not need 600 feet. Typically 15-20 feet work well, depending on what you secure to.
