Simple Setup in Under 30 Seconds

Instantly Fix Your Swing. Here's How:

Slide it on, cinch it down, swing. Hitters see a better swing in their first practice.

  1. Step 1: Slide on Top Hand


    Slide the loop onto your top hand over a batting glove or bare hand, with the leather facing outward.

  2. Step 2: Lock in your grip


    Hold the bat in your normal grip with both hands. Release your bottom hand, un-velcro the strap, and pull it down toward the knob.

  3. Step 3: Hit more bombs


    The pressure from your bottom hand will cinch the top hand downward, creating a secure connection and keep you in the zone longer.

Same Swing. More Connection. Better Result.

Left: without the strap. Right: with 9 STRAP. Watch the arms stay connected all the way through contact.

I thought it was just gonna be another gimmick, but this truly works. My 10-year-old ain't crossing his hands over no more and he is hitting dingers — two home runs and two triples since using it. He was losing a lot of power crossing those hands over. This product works. I've seen it firsthand.

It works. I promise. I bought this to help my son stop rolling his hands when batting. Not only has that stopped, but he hits so much more powerfully. I expected little and got a lot.

This fixes so many problems in your player's swing. If they let go of the bat mid-swing — fixed. If they roll over — fixed. It took my son from grounders to line drives in 2 games.

My son has been using this for a few days and I can see the difference in his swing already. Went from rolling over to hitting line drives.

So yes, it worked for me. I would roll over 2/3 of the time. I just used it this weekend and went 3-for-4 — the outfielder caught one or I would've gone a perfect 4-for-4. Highly recommend it.

I was skeptical spending the money, but it worked really well. My 12-year-old was rolling over in batting practice and hitting more grounders than he liked. He put the strap on and was instantly squaring up the ball. It's not a cure-all, but it made a real difference.
