Hi,

I purchased these aluminium extension ladders just over a year ago from Bunnings. However, when I came to use them last weekend I had terrible trouble opening them up. On closer inspection of the mechanism I noticed that it appeared the aluminium had picked between two of the surfaces:(( (see attachments). So this arvo I stripped the ladders apart and deburred the holes and cleaned up the surfaces as well as I could. I then put it back together and it is working a treat:). However, I know from past experience more than often it will happen again and I will have to go through the same process again.

I was wondering if I should just leave the surfaces clean and occassionaly blow any muck out with the aid of my compressor, or is there something I could use that will prevent some possible friction happening that will result in the material picking up again?

Thank you to those you are kind enough to reply.

Cheers
MH

I'd spray the mating surfaces with CRC Drylube (Teflon) before reassembly
