BTW: I'm done with my POP-LOCK - the PL5300 - Worst lock I have ever had on my Taco. I have removed it and gone back to the factory fitted handle. The pop-lock would not open all the time, it would work for a while then stop working for no reason. I re installed it, it then worked for a week then stopped working. I'm done with it.
If anyone wants to buy mine feel free to make me a decent offer. I have all the pieces screws and everything packaged nicely back in the factory packaging sitting in my garage.
