These slip-on foam palm grips are great for hand tools from small crescent wrenches, 14" pipe wrenches, and screwdrivers, up to 18” and 24” steel and aluminum pipe wrenches and larger tools. These slide over the handles of hand tools and dramatically improve the ergonomics by reducing the hard surface contact with the palm of your hand, reducing the gripping force you need, making it easier to torque or twist the tool, and keeping your hands away from the cold metal during outdoor use in the winter. Heavy winter gloves increase the gripping force necessary to securely hold hard faced tools, so this is a great way to reduce hand forces, fatigue, and risk of injury.
The grips are made out of an open cell polymer material that looks like it will last. It’s washable, but it doesn’t retain water like a sponge. The material gets a little stiffer at freezing temperatures, but it still works fine. To put them on just wet the surfaces with water or rubbing alcohol, slide it on, and let it dry.
There are three sizes: Small, Medium and Large to fit a wide range of hand tools. The Small has the contoured shape for easier gripping of small tools and the Medium and Larger sizes are designed so 18” and 24” aluminum pipe wrenches still fit inside my aluminum handle extenders. I should mention that the jury is still out on whether we really need the large size or we can get by with just the Medium. I've got all three sizes out to several utilities now and I hope to get their feedback by the end of March. As these are only $2 each I suggest you try all three sizes and see what fits.
