Self Lock Measuring Tape Hack
This is a quick modification to self lock tape measures to prevent them from creeping back into the housing.
Disassemble
Remove the screws and detach one side of the housing.
Tabs
Look at the shape of the tape measure lock wedge. If it is a scalene triangle we will need to modify it.
Cut
Cut the tabs off one edge of the wedge to create an isosceles triangle shape.
Reassemble
Reassemble the housing.
Test
Test the tape measure to be sure the retraction issue is resolved.
