Turn to Unlock — Lock Direction Indicator Plates

A pair of small, screw-mounted indicator plates that show which way to turn a knob, latch, or thumb-turn lock to unlock it.  Engraved text and an arrow for clean two-colour prints (or post-paint), plus countersunk holes so flat-head screws sit flush.

Dimensions

• Plate: 50 mm × 30 mm × 2.4 mm
• Corner radius: 3 mm (rounded, snag-free corners)
• Screw holes: Ø3 mm through-holes, 4 mm in from each side, vertically centred
• Countersinks: Ø6 mm at the surface, 1.2 mm deep — accepts standard M2.5–M3 flat-head / countersunk screws so they finish flush with the plate
• Engraving depth: 0.6 mm (arrow and text are recessed into the plate's top face)
