I'm not even sure what to call it! I want to make a rolling cart that is substantial enough for my wife to use as a cutting board, and to place heavy items she needs to move around the house. Making the cart is easy enough. My problem is finding something that will allow her to lock the wheels. She's in a wheelchair and not able to work a normal locking wheel that has a lever on the wheel itself. What I want is something that attaches to the upper portion of the cart that can be used to lock the cart in place. Appreciate any help or advice.
Thanks.
