The Socket Roll Metric Pro is made in the U.S.A. with double-layered nylon with PVC backed base fabric. With plastic straps behind the socket rows, high-grade military woven elastic, and patented locking stitch technology to keep sockets firmly secured, the Socket Roll Metric Pro is ideal for separating tools for job-specific tasks. It measures 14” by 14.5” rolled out flat and includes individual 1/4”, 3/8”, and 1/2” drives that are numbered to give users easy access to the deep and standard sockets they need quickly, with the 1/4” drive adding an additional 10” extension sleeve for those hard-to-reach places. Each Socket Roll Metric Pro features a convenient handle and hook/loop straps.
