Replacement Rung Lock for TecTake Telescope Ladder and identical Productsby
Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:1686847.
The original rung lock of the ladder has a constructional issue causing a predefined breakpoint at the begin of the lock tongues. So a lot of these locks breaks over the time and can't be bought separate. The new designed part does not have this problem and can be used instead of buying a complete new ladder.
