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.
