1/4 3/8 1/2 in Drive Extension Bar Stand
A three-tier bench stand that holds socket extension bars, wobble extensions and adapters upright. You drop each bar's male square drive into a square port. There are eight 1/4 in ports (6.75 mm, for the 6.35 mm drive), six 3/8 in ports (10.0 mm, for 9.525 mm) and five 1/2 in ports (13.15 mm, for 12.7 mm). Each port has a chamfered lead-in. The rows step up from 12 to 16 to 20 mm toward the back, so the taller bars stand behind the short ones. The footprint is 136 x 80 mm.
