Ridgid currently only makes the aluminum end pipe wrench up to a size 24 inch wrench. You do not make a 12 inch wrench, that is the most popular that plumbers use in conjunction with the 14 inch wrench. These are the most popular sizes that a professional plumber uses on a daily basis. However a 36 inch end wrench would be a great choice to make. As a professional that uses these tools every day the end wrenches work much more eficiently then a straight wrench and the steel end wrench at 36 inches is very heavy to use high up on a ladder. Please add a 36 inch aluminum end wrench to your lineup.
