Bending over to carry sheet goods in an uncomfortable position is less of an issue with a Stanley panel carry and Amazon has them in stock for $5.00 now. It’s one of those little things that make a big difference.
You have full control over the balance of the load and better visibility along the way. Add to that the strain you’re not putting on your back anymore from crouching over and trying to fit under a doorframe during the carry and it adds up to a bunch of saved hassle.
If you carry a bunch of sheet goods or are planning a big job five bucks will prevent a lot of pain.
