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.
1/4 3/8 1/2 in Ratchet Drive Wall Dock
A 140 x 46 mm screw-on wall plate with three bosses that stick out from the wall. Each boss has a square pocket for a ratchet's drive: 1/4 in (6.35 mm), 3/8 in (9.525 mm) and 1/2 in (12.7 mm). The pockets are 0.35 mm oversize so the drive's detent ball holds the ratchet, breaker bar or torque wrench with the handle hanging down. Gussets brace each boss, the pocket mouths are chamfered so the drive lines up as you push it in, and two countersunk holes take #8 wood screws.
